- 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 60W is the higher-power version of the 5RK series on a 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. Because it shares the same frame and mounting dimensions as the 40W model, the 60W gear motor is a straightforward upgrade path when your application demands more torque without changing the installation footprint.
Key Features
- Durable 90 mm frame engineered for continuous operation
- Reversible 30-minute rated duty for forward and reverse running
- 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 19.6 N·m (200 kg·cm)
- Higher torque capacity than the 40W unit with identical mounting
Applications
This 60W gear reducer motor handles a wide range of medium-duty equipment: belt and roller conveyors, packaging lines, mixing and blending devices, rotary feeders, and automated handling systems. Its higher allowable load makes it suitable for loads that start heavy or run continuously. When your drive requirements are even greater, browse the full small AC gear reducer motor range for the next power level.
How to Choose the Right Gear Motor
Confirm output speed, torque, voltage, frequency, and duty cycle against the allowable load table before ordering. For guidance, see our gear motor selection guide or contact Tenchuan with your load specifications.
FAQ
What voltages are available?
Single-phase 110V and 220V, plus a three-phase 220V version, in 50Hz and 60Hz ratings.
What is the rated torque of the 60W gear motor?
Rated torque is 246–670 mN·m depending on the model, with a maximum allowable load of 19.6 N·m at high ratios.
Can this motor run in reverse?
Yes, the reversible 30-minute rated models support forward and reverse operation.
Is the 60W model compatible with the 40W mounting?
Both units share the 90 mm frame and mounting pattern, simplifying upgrades between the two power ratings.
