Small AC Gear Reducer Motor 250W

The 6RK series AC gear motor (120–250W) is built with a durable 100mm frame and engineered for high-torque, heavy-duty industrial applications. It delivers powerful output, stable speed performance, and excellent reliability under continuous operation. With flexible single-phase and three-phase configurations, this motor is ideal for conveyors, automated production lines, and high-load mechanical systems.

  • Output Power: 120W – 250W
  • Voltage: 110V / 220V / 380V (Single-phase & Three-phase options)
  • Rated Speed: 1350 – 1550 r/min
  • Rated Torque: 740 – 1840 mN·m

  • The speed is based on the synchronous motor speed reduction ratio as a benchmark calculated by dividing the value of.Actual speed will vary the size of the load changes in less than the values shown in2~15%.
  • Hope to the table of the reduction ratio is greater than the further reduction,it would be installed between the motor and the reducer reduction ratiio of 10 the middle of the reducer.
  • When the load torque exceeds the maximum allowable load torque gear motor,and a locked rotor situation exists,please slow down box at the junction of the output shaft and load torque limit device installed to ensure the normal operation gearbox.
