3W AC Gear Motor Torque Motor with Gearbox Details

Tips: When the gear motor gets damp, how to solve?

In the actual production of the chemical enterprise, it is often found that some gear motors have not been used for a period of time. When they are turned on again, the insulation resistance of the gear motor windings is reduced. Especially during the rainy season, the air humidity is high and the insulation value may even be reduced to zero. At this time, dry processing should be performed so that the insulation resistance and absorption ratio can reach the specified value. If rushed in operation, it is possible to make the gear motor coil insulation breakdown, cause an accident. Using external heat source heating method can solve the problem of the dampness.

After the damped gear motor is dismantled and checked, the high-power incandescent light bulb is placed inside the gear motor to bake it, or the gear motor is placed in a drying room for drying. This method is easy to operate, safe and reliable, but it is only suitable for small gear motors that are easy to remove.

In this video, you will see wiring and testing a ATO single-phase 220V, 50Hz, 6W, 1250rpm torque motor with gearbox.
Firstly, we use a 250V 15A switch to transfer the direction of rotation of the motor.
Secondly, apply a 0.8μF capacitor to both ends of the blue and white wires of the motor and connect it to the transfer switch. The intermediate terminal of the transfer switch is connected to the power supply.
Finally, turn on the power and test.

Existing reviews of 3 W AC Gear Motor, Torque Motor with Gearbox, single phase

Very reliable

This motor runs smoothly. The small torque motor is perfect for light-duty equipment, and 3W is just right for light loads. It offers adjustable speed and great gear ratio options. Very reliable for small devices.

Small gearbox

I need a small gearbox, size: ≤ 40×40×40 mm, do you have this?

ATO Responded

Unfortunately, we don't have a gearbox with a size of ≤ 40×40×40 mm, but we have a gearbox with a size of 147×80×63 mm, does it meet your requirements?
