The Unimotor HD is a high dynamic brushless electronically commutated servo motor, designed for use in pulse duty applicaions where rapid acceleration and deceleration are required. With an extremely low range this motor is made for long-term, battery-operated applications that require small, accurate motion and dependability.

  • Connector variants, flying leads & 90° rotatable
  • Thermal protection by a KTY84.130 sensor
  • Torque range from 0.64 Nm to 10.2 Nm
  • Low winding voltages of 24 Vdc to 50 Vdc
  • Rated speeds from 1,000 to 6,000 rpm
  • Variety of flange possibilities (IEC/NEMA)
  • IP65 conformance, sealing against water spray & dust when mounted & connected with optional connectors (reduced to IP50 with flying leads)

t= 100°C winding 40°C maximum ambient. All data subject to +/-10% tolerance.
Stall torque, rated torque and power relate to maximum continuous operation tested in a 20°C ambient at 12kHz drive switching frequency.
All other figures relate to a 20°C motor temperature.
Maximum intermittent winding temperature is 140°C
