Small AC Gear Reducer Motor 250W

List of motor characteristics

6RK AC reduction motor (120~250W) (100mm)

• Parameters in above table refer to motor alone,without any load device.
• Permissible change in rated speed and rated current of the motor is within the range of±5%.

Allowable load for the gear motor

• 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.

Product Overview

The Small AC Gear Reducer Motor 250W is the highest-power standard model in the 6RK series on a heavy-duty 100 mm frame. It delivers rated torque from 740 to 1840 mN·m at 1350–1550 r/min at the top of the 120–250W power family. This 250W gear reducer motor provides the maximum output available in the 100 mm frame, delivering the strongest continuous rotation in the small AC gear reducer motor line.

Key Features

• Heavy-duty 100 mm frame with maximum-capacity windings
• Reversible 30-minute rated duty for forward and reverse operation
• Single-phase 110V/220V and three-phase 380V options at 50/60Hz
• Rated torque 740–1840 mN·m at 1350–1550 r/min
• Gear ratios from 3:1 to 500:1, maximum allowable load up to 43 N·m (440 kg·cm)
• Top torque capacity in the small AC gear motor family

Applications

This 250W gear reducer motor is chosen for the most demanding compact drives: heavy conveyors, industrial mixers, auger feeders, lifting and hoisting mechanisms, and large automation systems. When full output from the 100 mm frame is required, this is the unit to specify.
