The 3-Phase Gear Motors from 1.1kW to 3.7kW are a line of gear motors integrated with a mid-range gearbox combined with an electric motor, using a 3-phase 380V voltage, meeting stable transmission needs in many industrial and production fields. With the ability to reduce rotational speed and effectively increase torque, 3 phase gear motors help improve productivity and ensure durable operating performance.

Advantages of 3 phase gear motors from 1.1kW to 3.7kW

• High load capacity: Gear motors can operate stably under heavy load conditions, ensuring continuous production processes.
• Long service life: High-quality manufacturing materials and strict production processes help gear motors achieve a long lifespan, reducing maintenance and repair costs.
• Stable working performance: Gear motors operate stably with few incidents, helping to increase productivity and working efficiency.
• Easy installation and maintenance: Simple design makes the installation and maintenance of gear motors easy, saving time and costs.
• Diverse gear ratios: There are many different gear ratios, meeting various requirements of different applications.

Frequently Asked Questions

Why does a newly purchased gear motor leak black oil from the gearhead after running for just a few days?

The most common cause is that the installer forgot to remove the breather plug on top of the gearbox and replace it with the manufacturer’s provided ventilation cap. When the 3 phase motor runs, the gearbox generates heat, causing the air and oil inside to expand and increase pressure. Without a vent hole, this pressure will blow out the rubber oil seal, causing oil leakage.

How to wire a gear motor correctly?

In Vietnam, the industrial power supply is 3-phase 380V. If the motor nameplate indicates 220V/380V, you must connect it in a Star (Y) configuration so that the motor can withstand 380V. If you mistakenly connect it in a Delta (Δ) configuration, the motor windings will be subjected to overload voltage (380V instead of the 220V designed for delta circuits), leading to overcurrent, overheating, and immediate burnout after just a few minutes of operation.

How to safely reverse the rotation direction of a 3 phase gear motor running on a conveyor?

You just need to swap the positions of two of the three input phases (for example, keep phase R as is, and swap phases S and T) at the electrical cabinet terminal block or magnetic starter. However, with the power range from 1.1kW to 3.7kW, you must never reverse direction abruptly while the shaft is rotating at high speed; you must wait for the motor to come to a complete stop before pressing reverse to avoid chipping or breaking the gearbox gears due to reverse inertia.
