Unimotor fm is a high performance brushless AC servo motor range with frames from 075 mm to 250 mm, matched for use with Control Techniques servo drives. The ‘fm’ stands for Flexible Motor and is designed to accommodate a wide range of applications. The motors are available in seven frame sizes with various mounting arrangements and motor lengths.
Unimotor fm provides high-precision over an extended duration requiring lower acceleration and deceleration rates. The motor is optimized for high stability in precision profiling applications including:
Unimotor fm motors are a perfect match to Unidrive M and Digitax ST servo drives.
Unimotor fm offers the widest torque range, from 1.4 Nm – 136 Nm
Flexibility of the Unimotor range ensures the best fit for your application, options include:
Unimotor is suitable for a wide range of industrial applications, due to its extensive range of features:

Cables are an important part of a servo system installation. Not only must the noise immunity and integrity of the cabling and connectors be correct, but also SAFETY and EMC regulations must be complied with to ensure successful, reliable and fail safe operation. One of the most frequent problems experienced by motion systems engineers is incorrect connections of the motor to the drive.
Control Techniques ready made cables mean system installers can avoid the intricate, time consuming assembly normally associated with connecting servo systems. Installation and set-up time are greatly reduced - there is no fiddling with wire connections and crimp tools, and no fault finding.
The cables are available in lengths from 3m to 50m/100m (custom lengths available).

A passive wound device consisting of a stator and rotor elements excited from an external source, such as an SM-Resolver, the resolver produces two output signals that correspond to the sine and cosine angle of the motor shaft. This is a robust absolute device of low accuracy, capable of withstanding high temperature and high levels of vibration. Positional information is absolute within one turn - i.e. position is not lost when the drive is powered down.
An electronic device using an optical disc. The position is determined by counting steps or pulses. Two sequences of pulses in quadrature are used so the direction sensing may be determined and 4 x (pulses per rev) may be used for resolution in the drive. A marker pulse occurs once per revolution and is used to zero the position count. The encoder also provides commutation signals, which are required to determine the absolute position during the motor phasing test. This device is available in 4096, 2048 and 1024 ppr version. Positional information is non absolute - i.e. position is lost when the drive is powered down.
Types available are: Optical or Inductive - which can be single or multi-turn.
As previous but with extra gear wheels included so that the output is unique for each shaft position and the encoder has the additional ability to count complete turns of the motor shaft up to 4096 revolutions.
Available on both these types of encoders, and allows quick set-up times as the motor information is stored on board the encoder (075-250 motor only)
