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.

Summary

Installation

Location

Allow enough clearance for installing accessories and motor servicing when selecting a location.

Mounting

Adapter Bracket

The 220738A Adapter Bracket, positioned between the motor and the equipment, raises motor shaft height by 0.75 in. (19 mm).

Damper Linkages

The motor does not include a crank arm. Order the crank arm, included in the Q605 Linkage, separately.

Valve Linkages

The Q100 Linkage requires the 220738A Adapter Bracket for all valve applications.

Junction Box

When used with liquid-tight conduit connectors, the junction box provides NEMA 3 weather protection for the motor.

Settings and Adjustments

Auxiliary Switches

Adjustable cams actuate the auxiliary switches. These cams can be set to actuate the switches at any angle within the stroke.

Replacement

Damper Application

Turn off power and remove wiring from the old motor. Remove the crank arm from shaft of old motor.

Valve Application

When replacing a motor in a valve application, the linkage determines the necessity of the 220738A Adapter Bracket.
