KL-LM bevel servo geared motor without encoder

Features of KL-LM bevel servo gearmotor

  • Compact and highly dynamic thanks to direct mounting of the gearbox to the servo motor, without adapter or coupling.
  • Standard backlash 16–20 arcmin.
  • High precision: fractional gear ratio ensures no positioning errors.
  • Maintenance-free: no oil changes or servicing required.
  • Low-noise operation with helical bevel gears.
  • Continuous operation without additional cooling.
  • Radial shaft sealing: FKM on the input / NBR on the output.
  • Rigid output bearing due to preload.
  • Ambient temperature from 0°C to 40°C (other ranges available on request).
  • Maximum gearbox housing temperature ≤ 80°C.
  • Protection class IP65.
  • Ideal replacement for asynchronous motors.
  • Higher energy efficiency compared to comparable IE4 asynchronous motors.
  • Energy efficiency class IE5 in accordance with IEC/TS 60034-30-2.
  • Significantly lighter and more compact than comparable asynchronous motors.
  • Higher acceleration capability than asynchronous motors.
  • Robust design due to elimination of the encoder.
  • Resistant to vibration and shock.
  • Full control of speed and torque at low speeds and at standstill.
  • Only a standard power cable required, no encoder cables or shielding.
  • Wiring limited to the power supply connection cable only.
  • Freely rotatable power plug connector with quick-lock.
  • No cooling required at low rotational speeds.
  • Speed deviation less than 1%.
  • Compatible with SB6, SC6, and SI6 motor controllers (servo drives).

Positioning accuracy

  • ±1° without encoder.

Motor and compliance
