1. INTRODUCTION

This and the following instruction address the more common situations encountered in motor installation, operation and maintenance. For the TWMC motor warranty to be and to remain in effect, the motor must be installed and operated in strict accordance with the outline drawing, motor nameplates and these instructions and must not be altered or modified in any unauthorized manner.

During the installation and operation of motors in heavy industrial applications there is a danger of live electrical parts and rotating parts. Therefore to prevent injury and/or damage the basic planning work for installation, transportation, assembly, operation, etc... needs to be done and checked by authorized and competent personnel only.

Since these instructions cannot cover every installation, operation, and maintenance the following points should be considered and checked.

The technical data and information on permissible use such as assembly, connection, ambient and operating conditions given in the related catalogue, operating instructions, nameplates and other production documentation.

The general erection and safety regulations.

The local and plant-specific specifications and requirements.

The proper use of transport, lifting devices and tools.

The use of personal protective equipment.

Following indications should be observed when reading these instructions.

Safety instructions are marked as follows:

Warning of electric hazards for personnel.

Warning of dangers for personnel.

ATTENTION!

Warning of damage for the motor or installation.

2. ACCEPTING, INSPECTION, STORAGE, TRANSPORTATION

2.1 Inspection upon receipt

Check the following points upon receipt:

•Are the nameplate ratings identical with what you ordered?

•Are dimensions and color in compliance with your specifications?

•Are the nameplate ratings for space heater, thermal protector, temperature detector, etc. identical with what you ordered?

•Is there any damage?

•Are all accessories and accompanying instruction manuals in good order?

•Please ensure that the arrow head indicator really indicates direction of rotation.

•If there is any specific requirements, please ensure they are in conformity with your specifications.

2.2.1 Storage

When motors are not in operation, the following precautionary measures should be undertaken to assure best performance.

2.2.2 Place

(a)High and dry, well ventilated without direct sun, dust or corrosive gas.

(b)Not located near a boiler or freezer.

(c)Entirely free from vibration and easy movement.

(d)Motors should be put on pallets to prevent moisture.

2.2.3

Motors should be well-shielded form dust, but under well-ventilated circumstances.

2.2.4 Moisture prevention

Since moisture can be very detrimental to electrical components, the motor temperature should be maintained about 3ºC above the dew point temperature by providing either external or internal heat. If the motor is equipped with space heaters, they should be energized at the voltage shown by the space heater nameplate attached to the motor. Incandescent light bulbs can be placed within the motor to provide heat. However, if used, they must not be allowed to come in contact with any parts of the motor because of the concentrated hot spot that could result.

2.2.5

Even during storage, the insulation resistance should be kept above the specified values.

(a)For measurement of insulation resistance and acceptable standard values, please refer to measures stated in 4.1.2 “Measurement of insulation resistance”.

(b)Insulation resistance test should be performed once every three months.

2.2.6

If the motor is not in operation for a long period (one week and above) after installation or has been in operation but stopped for a period of time, the following precautions must be taken.

(a)Protect the motor as measures stated in 2.2.4.

(b)Insulation resistance test should be performed as stated in 2.2.5.

2.2.7Bearing protection

(a)If the motor has been provided with a shaft shipping brace to prevent shaft movement during transit, it must be removed before operating the motor. It is very important that this brace be re-installed exactly as it was originally, before the motor is moved from storage or any time when the motor is being transported. This prevents axial rotor movement that might damage the bearings.

(b)Motors equipped with sleeve bearings are shipped from the factory with the bearing oil reservoirs drained. In storage, the oil reservoirs should be properly filled to the center of the oil level gauge with a good grade of rust inhibiting oil. This will keep the bearing journals well oiled to prevent rusting. The motor shaft should be rotated several revolutions every month ensuring the shaft does not come to rest in its original position. While the shaft is rotating, it should be pushed to both extremes of the endplay.

(c)Motors with anti-friction bearings are properly lubricated with the correct grade of grease at the factory and no further greasing is required in storage. The shaft should be rotated several revolutions every month to maintain proper distribution of the grease within the bearings.

(d)Tilt-pad bearings are a type of sleeve bearing used in special design applications. Due to the nature of this bearing, a loose oil ring for delivering lubricant cannot be provided. Therefore, during the storage internal, oil must be periodically manually introduced into the pads and housing to prevent the occurrence of oxidation of the precision machined components.

(1)Remove the pipe plug from the bearing cap located above the tilt-bearing shell.

(2)Pour in approximately one cup of oil every month and rotate the shaft a few revolutions about every two (2) weeks.

(3)For long periods of storage, the oil that accumulates in the housing should be removed.

2.2.8

ATTENTION!

Care should be taken to keep parts such as fitting surfaces, key, shaft extension and axial central hole from any collision with foreign matter. Grease should also be generously applied to prevent rusting.

2.2.9 Transportation

To keep the rotating parts of motors from moving, thus preventing damage and scratching during transportation, they should be held securely with a locking device. Remove all transit clamps before operating the motor. It is very important that this device be reinstalled exactly as it was originally, before the motor is moved from storage or any time when the motor is being transported. The vertical mounting type motors should be transported in the vertical position.

Do not use the hoisting hook/eyebolts to lift more than the motor itself. They are designed to support the motor only. Make sure the hoisting hook is correctly attached to the eyebolt(s)/lug(s) and that they are fully screwed in before hoisting. Also note such parts as fan cover, ventilation box, bracket, slip-ring, etc. may have their own hoisting lugs which can only carry their own weight. Nothing extra should be attached while hoisting.

Do not twist the steel wires and make sure the eyebolts have been firmly screwed and the sling angle is correct.

3 INSTALLATION

Motor installation – site and environment 3.1.1

Standard environment and site conditions for the installation of motors are usually set as follows:

(a)Ambient temperature: -10~40ºC

(b)Humidity: Relative humidity below 90%RH for totally enclosed types, and below 80%RH for semi-enclosed types.

(c)Elevation: below 1000 meters or 3300 feet.

(d)Harmful gases, liquids, dusts, high moisture should be absent.

(e)Foundations should be strong and free of vibration.

If there are any special environmental conditions, please inform TWMC prior ordering.

3.1.2Ventilation and space

(a)Installation area should be well ventilated.

(b)The installation space should be large enough to facilitate heat dissipation and maintenance.

3.2 Foundation 3.2.1

Use rigid and solid sole plate or common bed as foundation.

For best motor performance, it is advisable to use a sole plate or common bed, particularly when using a shaft coupling.

3.2.2Installation

(a)Select an appropriate foundation surface for the sole plate or common bed, which will be, considered the ultimate level.

(b)Align the position of the common bed with reference to that level.

(c)Align the level accuracy at least at four points such as bearing mounting, shaft extension etc. The accuracy should be within 0.04mm or .0015 inches

(d)Sole plate or common bed should be embedded in concrete foundation as illustrated in Fig.

3.Stiff pads should also be installed beneath the wedges, which are welded together at various spots about 400-500mm (15.75-1 9.70 inches) apart. This will enable the foundation to evenly carry the weight of the whole motor.

(e)The base should be sturdy and rigid to keep it flat and level.

(f)Make sure the mortar and concrete are completely dry, and the precision of the level is acceptable, and then set the motor on the mounting foundation.

(g)Accurately install shaft couplings, belt sheaves

etc., then weld the wedges solid to prevent any change in position.

3.2.3 The foundation of vertical induction motors: (Also the foundation of pump)

(a)Foundation of motor/pump must be rigid and secure to provide adequate support. There must be no vibration, twisting, misalignment etc. due to inadequate foundations.

(b)A massive concrete foundation is preferred in order to minimize vibration. Rigidity and stability are enhanced by prop plate and foundation bolt. As shown in Fig. 4.
