Induction Gear Motors
A geared induction motor is a drive unit that integrates a squirrel-cage induction motor with a reduction gear (gearhead). It reduces the motor speed according to the gear ratio and increases torque. It can run directly on the commercial power supply, and its simple structure makes it easy to maintain. Three-phase and single-phase types are available, and the gearhead shaft arrangements include parallel shaft, right-angle shaft, and hollow shaft. Models with an electromagnetic brake are used for lifting applications that require holding the load when stopped. They are widely used in conveyors, hoists, and drive sections of large equipment. In recent years, some products have also been designed to meet national high-efficiency regulations and reduce weight by using an aluminum gearhead case.

How to choose Induction Gear Motors
-
1. Determine Motor Capacity from Required Output
Calculate the required power from the load torque and required rotational speed, then select a rated output with a margin. Listed products range from 0.1 to 2.2 kW. Insufficient capacity causes overheating and starting failure, while excessive capacity reduces efficiency and increases equipment size.
-
2. Match Output Speed Using the Gear Ratio
The output shaft speed is the motor speed divided by the gear ratio, and it varies with the power supply frequency (50 Hz/60 Hz) and number of poles. Select a gear ratio that matches the required speed on the equipment side, and verify the rotational speed at the frequency used in the installation region.
-
3. Do Not Exceed the Allowable Output Shaft Torque
A larger gear ratio increases output torque, but the gears and bearings of the reducer have allowable limits. Apply factors for starting and impact to the load torque, and select a frame size and gear ratio combination that stays within the allowable output shaft torque.
-
4. Verify Power Supply and Destination Standards
Confirm that the number of phases (single-phase or three-phase), supply voltage, and frequency match the installation site power supply. For equipment exported overseas, compliance with standards such as UL, CE, and CCC, or with high-efficiency regulations such as China's GB Grade 3, may be required.
-
5. Compatibility of Frame Size, Mounting, and Shaft Arrangement
The frame size indicates the gearhead frame size and is related to mounting dimensions and output shaft diameter. Check it together with foot or flange mounting and the parallel shaft, right-angle shaft, or hollow shaft type. When replacing existing equipment, confirm that the mounting dimensions are identical.
-
6. Mass and Use of Weight-Reduced Models
Listed products have a mass of 33 to 42.7 kg. Products with an aluminum gearhead case are reported to be 29 to 37% lighter than conventional models. Consider them when reducing the workload of assembly or simplifying the equipment frame.
