The Series 90 Modutrol IV™ Motors are spring return and
non-spring return modulating proportional control motors. Use
these motors with controllers that provide a Series 90 output
to operate dampers or valves.

PRODUCT DATA
FEATURES
• Replaces M934A,D, M941, M944A,C,D, M945A,D,F,
M954, M965, and M975 motors.
• Integral junction box provides NEMA 3 weather
protection.
• Integral spring return returns motor to normal position
when power is interrupted.
• Motor and circuitry operate from 24 Vac. Models
available with factory installed transformer, or a field
added internal transformer.
• Quick-connect terminals are standard—screw terminal
adapter is available.
• Adapter bracket for matching shaft height of older
motors is available.
• Motors have field adjustable stroke (90° to 160°).
• Die-cast aluminum housing.
• Integral auxiliary switches are available factory
mounted, or can be field added.
• Nominal timing standard of 30 seconds (90° stroke),
and 60 seconds (160° stroke). Other timings available.
• Spring return motors can operate valve linkages form
power end or auxiliary end shafts for normally closed
or normally open valve applications.
• All models have dual shafts (slotted and tapped on
both ends).
• All models have auxiliary switch cams.
• Fixed torque throughout the entire voltage range.
• Motors are designed for either normally open or
normally closed valves and dampers.
• Field addable interface modules can be mounted in the
junction box to upgrade the motor to Series 70
(electronic) control.

a
Timings apply to all TRADELINE models. Some OEM models are available with non-standard timing/torque.
b
The torque rating for dual-ended shaft motors is the sum of the shaft torques (power-end torque plus auxiliary-end torque).
c
Breakaway torque is maximum torque available to overcome occasional large loads such as a seized damper or valve.
d
Low timing is for M9184D1005 only.
NOTE: Some 150 lb-in. and 300 lb-in. torque adjustable stroke motors have timings that are twice that of the nominal timing.
IMPORTANT
Never use a Modutrol Motor continuously at the
Breakaway Torque rating.

INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment circuitry.
Disconnect all power supplies before installation.
Motors with auxiliary switches can have more than one
disconnect.
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear train
and stroke limit contacts.
IMPORTANT
Always conduct a thorough checkout when
installation is complete.
Location
Allow enough clearance for installing accessories and motor
servicing when selecting a location (See Fig. 2). If located
outdoors, use liquid-tight conduit connectors with the junction
box to provide NEMA 3 weather protection. If mounted
outdoors in a position other than upright, install a 4074ERU
Weatherproofing Kit and liquid-tight connectors to provide
NEMA 3 protection.
Motor Damage Hazard.
Deteriorating vapors and acid fumes can damage
metal parts.
Install motor in areas free of acid fumes and other
deteriorating vapors.
In excessive salt environments, mounting base and screws
should be zinc or cadmium plated, not stainless steel or brass.
Use the 220738A Adapter Bracket for mounting on these
surfaces.
