Introducing the DutymAx motor
Years of experience of designing specialised brushless motors for Defence applications, Aerospace
and Space Satellites instrumentation has been focused on the demands of the industrial controls
market. Originally designed to be a vital element in Control Techniques own motion controls and
servo drives, these motors are now available as a standalone component. Similarly, the feedback
device, resolver, owes much to the heritage of the company and its skills in the design and
manufacture of rotating components. The company is now offering to system builders worldwide, this
range of components based on high quality and sophisticated design, coupled with ISO9001 quality
assured manufacture.
The DutymAx servo motors have excellent power to size ratio giving optimal dynamic response. This
is provided by a superior design of magnetic circuit within the motor, using high energy rare earth
magnets, and a low inertia laminated rotor and a high slot fill stator.
The shaft resolver is mounted directly onto the motor offering a robust and accurate measuring
system for speed and position signals to suit most drives and control system requirements.
The motors are available in four frame sizes, 75, 95,115 and 142 mm square body.

The brakes are intended for parking duty and engage on power de-energisation.
Refer to drive centre if your application requires dynamic braking in emergency conditions.
To provide protection to the brake control circuit it is recommended that a diode is connected
across the output terminals of the solid state or relay contacts devices. Ask for detailed
information.
Motor length is identical with or without brake.
