Basic Understanding Of Hub Motor
Leave a message
Vshida micro-motor robot hub motors are mainly divided into three categories, namely reducer hub servo motors, outer rotor gearless hub motors and outer rotor gear hub motors. The following three motors will be introduced to you.
1. Reducer hub servo motor
This is a traditional structure of the hub motor, the basic structure is a servo motor plus a planetary reducer plus a wheel structure. Because of the existence of the geared motor, even if the motor outputs a large torque, its internal current does not need to be too high, so the in-wheel motor of this structure can stably output a large torque for a long time. Moreover, the deceleration and buffering effect of the reducer is obvious, which increases the working stability and safety of the in-wheel motor. These advantages are very suitable for the heavy-duty AGV industry, and also make the heavy-duty AGV industry develop rapidly.
2. Outer rotor gearless hub motor
This is a new type of in-wheel motor, the basic structure is stator, encoder, shaft, magnet, steel ring, cover, tire.
This in-wheel motor has obvious advantages, such as small size, simple structure, fast power response, low cost, easy installation, etc. It is very suitable for mobile robots with a load of less than 300kg, such as food delivery robots, cleaning robots, disinfection robots, small load handling robots, Sorting robots and inspection robots, etc. This in-wheel motor has a wide range of applications, covering all kinds of places in human life.
3. The outer rotor has a geared hub motor
This is a brand-new outer rotor hub motor, which is rarely known in the industry. Its basic structure is an outer rotor gearless hub motor, a gear (reducer), and the gear is installed between the motor stator and the output shaft. Reduce the speed according to the reduction ratio and increase the output torque on the shaft. By adding a reducer, the torque of the outer rotor hub motor is increased, so that it can meet the application of heavy-duty robots, expand the application range of the outer rotor hub motor, and simplify the structure of the heavy-duty robot hub motor, which greatly promotes the robot industry. develop.
