Small AC Gear Reducer Motor 40W

List of motor characteristics

5RK AC deceleration motor (40/60W) (90mm)

• 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%.

• 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 40W belongs to the 5RK series and is built on a robust 90 mm frame. It pairs a reversible AC induction motor with a matched reduction gearbox to deliver rated torque from 246 to 670 mN·m at 1300–1550 r/min. This 40W geared motor shares the same frame and transmission family as the 60W model, which makes it a convenient drop-in option when your machine needs moderate torque with flexible single-phase or three-phase supply.

Key Features

• Sturdy 90 mm frame rated for continuous industrial service
• Reversible 30-minute rated duty for forward and reverse operation
• Single-phase 110V/220V and three-phase 220V options at 50/60Hz
• Rated torque 246–670 mN·m at 1300–1550 r/min
• Gear ratios from 3:1 to 500:1, maximum allowable load up to 9.81 N·m (100 kg·cm)
• Matched motor-and-gearbox design simplifies mounting and alignment

Applications

This 40W AC gear reducer motor suits medium-duty machinery such as small conveyors, packaging and filling equipment, mixing paddles, rotary turntables, and automated assembly stations. Its reversible rating also suits gates, doors, and positioning mechanisms. For loads at the upper end of this frame size, explore the full small AC gear reducer motor range.

How to Choose the Right Gear Motor

Check the required output torque and speed against the allowable load table, then confirm voltage, frequency, and duty cycle. Read our gear motor selection guide for a step-by-step method, or contact Tenchuan with your application data.
