Series 90 
Modutrol IV

 Motors

APPLICATION

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.

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.
