The HSM1 is characterized by a high and constant starting torque from zero speed. From a speed of 3’600 rpm, the motor offers continuous power up to maximum speed. It is therefore ideally suited for electric vehicles that need to achieve high initial acceleration as well as high final speeds without a manual gearbox.


  • High power density
  • Minimal torque ripple
  • Minimal drag losses
  • Constant power and high efficiency over a wide speed range
  • Intrinsically safe (induced voltage at max. speed and passive inverter < 500 VDC)
  • Low short circuit torque
  • The HSM1-6.17.12 is optionally available with different gearbox types

The HSM1-6.17.12 is in B-sample status
