Safety Notice Continued

WARNING:	Use proper care and procedures that are safe during handling, lifting, installing, operating and
	maintaining operations. Improper methods may cause muscle strain or other harm.
WARNING:	Pacemaker danger − Magnetic and electromagnetic fields in the vicinity of current carrying
	carrying conductors and permanent magnet motors can result result in a serious health hazard to
	persons with cardiac pacemakers, metal implants, and hearing aids. To avoid risk, stay way from
	the area surrounding a permanent magnet motor.
WARNING:	Before performing any motor maintenance procedure, be sure that the equipment connected to
	the motor shaft cannot cause shaft rotation. If the load can cause shaft rotation, disconnect the
	load from the motor shaft before maintenance is performed. Unexpected mechanical rotation of
	the motor parts can cause injury or motor damage.
WARNING:	Do not use non UL/CSA listed explosion proof motors in the presence of flammable or
	combustible vapors or dust. These motors are not designed for atmospheric conditions that
	require explosion proof operation.
WARNING:	Motors that are to be used in flammable and/or explosive atmospheres must display the UL label
	on the nameplate along with CSA listed logo. Specific service conditions for these motors are
	defined in NFPA 70 (NEC) Article 500.
WARNING:	Guards must be installed for rotating parts such as couplings, pulleys, external fans, and unused
	shaft extensions, should be permanently guarded to prevent accidental contact by personnel.
	Accidental contact with body parts or clothing can cause serious or fatal injury.
Caution:	To prevent premature equipment failure or damage, only qualified maintenance personnel should
	perform maintenance.
Caution:	Do not over tension belts. Excess tension may damage the motor or driven equipment.
Caution:	Do not over−lubricate motor as this may cause premature bearing failure.
Caution:	Do not lift the motor and its driven load by the motor lifting hardware. The motor lifting hardware
	is adequate for lifting only the motor. Disconnect the load (gears, pumps, compressors, or other
	driven equipment) from the motor shaft before lifting the motor.
Caution:	If eye bolts are used for lifting a motor, be sure they are securely tightened. The lifting direction
	should not exceed a 20 angle from the shank of the eye bolt or lifting lug. Excessive lifting
	angles can cause damage.
Caution:	To prevent equipment damage, be sure that the electrical service is not capable of delivering more

	information please contact your Baldor distributor or an Authorized Baldor Service Center.
Receiving	Each Baldor Electric Motor is thoroughly tested at the factory and carefully packaged for shipment. When
	you receive your motor, there are several things you should do immediately.
	1. Observe the condition of the shipping container and report any damage immediately to the
	commercial carrier that delivered your motor.
	2. Verify that the part number of the motor you received is the same as the part number listed on your
	purchase order.
Handling	The motor should be lifted using the lifting lugs or eye bolts provided.
Caution:	Do not lift the motor and its driven load by the motor lifting hardware. The motor lifting hardware
	is adequate for lifting only the motor. Disconnect the load (gears, pumps, compressors, or other
	driven equipment) from the motor shaft before lifting the motor.
	1. Use the lugs or eye bolts provided to lift the motor. Never attempt to lift the motor and additional
	equipment connected to the motor by this method. The lugs or eye bolts provided are designed to lift
	only the motor. Never lift the motor by the motor shaft or the hood of a WPII motor.

1−2 General Information

MN408

2.To avoid condensation inside the motor, do not unpack until the motor has reached room temperature. (Room temperature is the temperature of the room in which it will be installed).

The packing provides insulation from temperature changes during transportation.

3.When lifting a WPII (Weather Proof Type 2) motor, do not lift the motor by inserting lifting lugs into holes on top of the cooling hood. These lugs are to be used for hood removal only.

A spreader bar should be used to lift the motor by the cast lifting lugs located on the motor frame.

4.If the motor must be mounted to a plate with the driven equipment such as pump, compressor etc., it may not be possible to lift the motor alone. For this case, the assembly should be lifted by a sling around the mounting base. The entire assembly can be lifted as an assembly for installation.

Do not lift the assembly using the motor lugs or eye bolts provided. Lugs or eye bolts are designed to lift motor only. If the load is unbalanced (as with couplings or additional attachments) additional slings or other means must be used to prevent tipping. In any event, the load must be secure before lifting. If the load is unbalanced (as with couplings or additional attachments) additional slings or other means must be used to prevent tipping. In any event, the load must be secure before lifting.

Storage Storage requirements for motors and generators that will not be placed in service for at least six months from date of shipment.

Improper motor storage will result in seriously reduced reliability and failure. An electric motor that does not experience regular usage while being exposed to normally humid atmospheric conditions is likely to develop rust in the bearings or rust particles from surrounding surfaces may contaminate the bearings. The electrical insulation may absorb an excessive amount of moisture leading to the motor winding failure.

A wooden crate “shell” should be constructed to secure the motor during storage. This is similar to an export box but the sides & top must be secured to the wooden base with lag bolts (not nailed as export boxes are) to allow opening and reclosing many times without damage to the “shell”.

Minimum resistance of motor winding insulation is 5 Meg ohms or the calculated minimum, which ever is greater. Minimum resistance is calculated as follows: Rm = kV + 1

where: (Rm is minimum resistance to ground in Meg−Ohms and kV is rated nameplate voltage defined as Kilo−Volts.)

Example: For a 480VAC rated motor Rm =1.48 meg−ohms (use 5 M ). For a 4160VAC rated motor Rm = 5.16 meg−ohms.

Preparation for Storage

1.Some motors have a shipping brace attached to the shaft to prevent damage during transportation. The shipping brace, if provided, must be removed and stored for future use. The brace must be reinstalled to hold the shaft firmly in place against the bearing before the motor is moved.

2.Store in a clean, dry, protected warehouse where control is maintained as follows:

a.Shock or vibration must not exceed 2 mils maximum at 60 hertz, to prevent the bearings from brinelling. If shock or vibration exceeds this limit vibration isolation pads must be used.

b.Storage temperatures of 10 C (50 F) to 49 C (120 F) must be maintained.

c.Relative humidity must not exceed 60%.

d.Motor space heaters (when present) are to be connected and energized whenever there is a possibility that the storage ambient conditions will reach the dew point. Space heaters are optional.

Note: Remove motor from containers when heaters are energized, reprotect if necessary.

3.Measure and record the resistance of the winding insulation (dielectric withstand) every 30 days of storage.

a.If motor insulation resistance decreases below the minimum resistance, contact your Baldor District office.

b.Place new desiccant inside the vapor bag and re−seal by taping it closed.

c.If a zipper−closing type bag is used instead of the heat−sealed type bag, zip the bag closed instead of taping it. Be sure to place new desiccant inside bag after each monthly inspection.

d.Place the shell over the motor and secure with lag bolts.

4.Where motors are mounted to machinery, the mounting must be such that the drains and breathers are fully operable and are at the lowest point of the motor. Vertical motors must be stored in the vertical position. Storage environment must be maintained as stated in step 2.

5.Motors with anti−friction bearings are to be greased at the time of going into extended storage with periodic service as follows:

a.Motors marked “Do Not Lubricate” on the nameplate do not need to be greased before or during storage.

b.Ball and roller bearing (anti−friction) motor shafts are to be rotated manually every 3 months and greased every 6 months in accordance with the Maintenance section of this manual.

c.Sleeve bearing (oil lube) motors are drained of oil prior to shipment.

The oil reservoirs must be refilled to the indicated level with the specified lubricant, (see Maintenance). The shaft should be rotated monthly by hand at least 10 to 15 revolutions to distribute oil to bearing surfaces.

d.“Provisions for oil mist lubrication” – These motors are packed with grease. Storage procedures are the same as paragraph 5b.

e.“Oil Mist Lubricated” – These bearings are protected for temporary storage by a corrosion inhibitor. If stored for greater than 3 months or outdoor storage is anticipated, connected to the oil mist system while in storage. If this is not possible, add the amount of grease indicated under “Standard Condition” in Section 3, then rotate the shaft 15 times by hand.

6.All breather drains are to be fully operable while in storage (drain plugs removed). The motors must be stored so that the drain is at the lowest point. All breathers and automatic “T” drains must be operable to allow breathing and draining at points other than through the bearings around the shaft. Vertical motors should be stored in a safe stable vertical position.

7.Coat all external machined surfaces with a rust preventing material. An acceptable product for this purpose is Exxon Rust Ban # 392.

8.Carbon brushes should be lifted and held in place in the holders, above the commutator, by the brush holder fingers. The commutator should be wrapped with a suitable material such as cardboard paper as a mechanical protection against damage.

Non−Regreaseable Motors

Non−regreasable motors with “Do Not Lubricate” on the nameplate should have the motor shaft rotated 15 times to redistribute the grease within the bearing every 3 months or more often.

All Other Motor Types

Before storage, the following procedure must be performed.

1.Remove the grease drain plug, if supplied, (opposite the grease fitting) on the bottom of each bracket prior to lubricating the motor.

2.The motor with regreasable bearing must be greased as instructed in Section 3 of this manual.

3.Replace the grease drain plug after greasing.

4.The motor shaft must be rotated a minimum of 15 times after greasing.

5.Motor Shafts are to be rotated at least 15 revolutions manually every 3 months and additional grease added every nine months (see Section 3) to each bearing.

6.Bearings are to be greased at the time of removal from storage.

Removal From Storage

1.Remove all packing material.

2.Measure and record the electrical resistance of the winding insulation resistance meter at the time of removal from storage. The insulation resistance must not be less than 50% from the initial reading recorded when the motor was placed into storage. A decrease in resistance indicates moisture in the windings and necessitates electrical or mechanical drying before the motor can be placed into service. If resistance is low, contact your Baldor District office.

3.Regrease the bearings as instructed in Section 3 of this manual.

4.Reinstall the original shipping brace if motor is to be moved. This will hold the shaft firmly against the bearing and prevent damage during movement.
