Harmonic reducer manufacturers-the difference between torque motor and harmonic reducer

2023-09-11

Torque motors and harmonic reducers are widely used transmission equipment, but they are two different types of motors. They have some differences in working principles, application scenarios and performance characteristics, so what are the specific ones? Today, harmonic reducer manufacturers will analyze the difference between torque motor and harmonic reducer. Let's take a look. Torque motor, also known as torque motor, is a motor specially used to provide large torque output. Harmonic reducer manufacturers said that it is a special motor with soft mechanical characteristics and wide speed range. Torque motor belongs to a special motor with many stages, it can continue to run at low speed or even when the motor is locked (that is, the rotor cannot rotate) without causing damage to the motor. In this working mode, the motor can provide stable torque to the load (hence the name torque motor).

The structure of torque motor is donut, which is divided into outer rotor motor with rotor in outer ring, stator in inner ring, inner rotor motor with stator in outer ring and inner rotor motor with rotor in inner ring. The manufacturer of harmonic reducer disclosed that because the outer rotor can generate larger torque under the same size, it is often used in outer rotor motor, and its main feature is that it can output larger torque in a short time, it is suitable for applications that need to start or drive large loads, such as lifting machinery, machine tools, textiles, wire and cable, metal processing, papermaking, rubber, plastics, printing machinery and other industrial fields. Torque motors usually use DC motors or asynchronous motors as driving sources, Increase the output torque by increasing the intensity of the magnetic field or changing the wiring method of the windings. Torque motors usually have higher torque (current ratio), however, the speed is low and the speed adjustment range is small.

On the other hand, the harmonic reducer is a motor that adds a deceleration device to the output shaft of the motor. Its main function is to reduce the speed of the output shaft and increase the output torque. The harmonic reducer manufacturer tells you that the harmonic reducer usually uses a DC motor, Asynchronous motor or stepping motor is used as the driving source, and deceleration is realized by using deceleration mechanisms (such as gears, belts, worms, etc.). The reduction ratio of the harmonic reducer can be selected according to actual demand, provide a variety of different speed output, harmonic reducer is suitable for applications that need to accurately control the speed and provide large torque, such as automation equipment, mechanical arms, etc., from the application scenario, torque motor will be more suitable for starting or driving large load occasions, while harmonic reducer is mainly used for occasions that need to reduce the speed and provide large torque, torque motor can provide large starting torque at the moment of starting, it can quickly start heavy loads, and the harmonic reducer realizes the deceleration of the output shaft and increases the output torque through the deceleration device. It is suitable for applications that require precise control at higher speeds. From the performance characteristics, torque motors usually have Higher torque (current ratio), but its output speed is low and the speed adjustment range is small.
