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:

  • Printing
  • Winding
  • Labeling

Unimotor fm motors are a perfect match to Unidrive M and Digitax ST servo drives.

Wide torque range

Unimotor fm offers the widest torque range, from 1.4 Nm – 136 Nm

Maximum flexibility

Flexibility of the Unimotor range ensures the best fit for your application, options include:

  • Various feedback devices to be used. As standard an incremental encoder is fitted as this offers an optimum balance of cost and performance. SinCos, EnDAT and Hiperface can be selected for increased resolution and Resolver feedback is available for increased reliability in extreme environments.
  • High inertia versions are available to allow the motor inertia to be more closely matched to the load inertia for increased performance and stability.
  • Motor brakes may be integrated within the motor.
  • Type of connectors fitted.
  • Various voltage and speed ranges are available.
Unimotor is suitable for a wide range of industrial applications, due to its extensive range of features

  • Torque range: from 1.4 Nm to 136 Nm.
  • Standard 24 V parking brake option.
  • Numerous connector variants, e.g. vertical, 90° low profile, 90° rotatable and hybrid box on frame size 190 and 250.
  • Variety of flange possibilities (IEC/NEMA).
  • Various shaft diameters; keyed or plain.
  • IP65 conformance; sealed against water spray and dust when mounted and connected.
  • Low inertia for high dynamic performance; high inertia option available.
  • World class performance.
  • Supported by rigorous testing for performance and reliability.
  • Optional high peak torque motors; up to 5 times stall torque.
  • Winding voltages of 460 V and 230 V.
  • Rated speeds include 1500 rpm, 2000 rpm, 3000 rpm, 4000 rpm, 6000 rpm and others available.
  • IP65 environmental protection is standard.

Cables

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).

Cable range for motor-drive combination

  • Unimotor fm E3/U3 to Unidrive M and Digitax ST
  • E3 to Epsilon or EP

Power cable variants

  • Phase conductors 1.0mm² (10A) to 16mm² (70A)
  • With and without brake wire pairs
  • Motor end connector
  • Motor end Ferrules for Hybrid box
  • Drive end is tailored to suit the drive and can be Ferrules or Ring terminals

Cable features

  • For dynamic performance PUR outer sheath for oil resistance and dynamic performance. The PUR jacket has excellent abrasion, chemical and ozone resistance, low smoke, low halogen flame retardant construction suitable for internal and external industrial environments.
  • Complies with DESINA coding – Orange for power, Green for signal
  • Power cable and plugs UL recognized
  • Optimum noise immunity
  • Encoder cable has low volt drop for long cable lengths and separately screened thermistor wires.
  • No need for crimp and insertion / removal tools
  • Production build gives quality and price benefits
  • Braided screen for greater flexibility and wear
  • Power cables with and without brake wires
  • Cable assembly type identification label
  • Brake wires are separately shielded within the power cable

Fan Box (field fitted)

  • Available for 075 to 190.
  • One fan box per frame size.
  • Easy assembly onto fm motors using two screws per side fitting into existing Unimotor fm housing slots.
  • Fan blown models available with higher performance (E5/U5 models).

Feedback

Resolver

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.

Incremental Encoder

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.

SinCos/Absolute Encoders

Types available are: Optical or Inductive – which can be single or multi-turn.

  • Optical: An electronic device using an optical disc. An absolute encoder with high resolution that employs a combination of absolute information, transmitted via a serial link, and sine/cosine signals with incremental techniques.
  • Inductive: An electronic device using inductively coupled PCB’s. An absolute encoder with medium resolution that employs a combination of absolute information, transmitted via a serial link, and sine/cosine signals with incremental techniques. This encoder can be operated with the drive using either sine/cosine or absolute (serial) values only. Positional information is absolute within 4096 turns – i.e. position is not lost when the drive is powered down.

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.

Electronic nameplating

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).
