What are the commonly used speed regulation methods for micro gear motors?

The main function of the micro gear motor is to provide low-speed high-torque output. The output speed of the micro gear motor is closely related to the reduction ratio and input speed of the micro motor. Once the reduction ratio is determined, the speed of the micro gear motor is basically fixed, but the speed of the gear motor needs to be adjusted during the application process...

The main function of the micro gear motor is to provide low-speed high-torque output. The output speed of the micro gear motor is closely related to the reduction ratio and input speed of the micro motor. Once the reduction ratio is determined, the speed of the micro gear motor is basically fixed, but the speed of the gear motor needs to be adjusted and changed during the application process. The following is a brief description of the speed regulation method of the micro geared motor.

The deceleration and speed regulation of micro gear motor are two different concepts. Speed regulation is to adjust the output speed of the micro DC motor by changing the DC voltage. The output torque is affected by the number of gear stages. The more gear stages, the slower the output speed, the greater the torque, and the greater the efficiency loss. There are two ways of speed regulation and stepless speed regulation. Among them, the stepped speed regulation is simple and convenient, and the cost is low. It is generally used in occasions where the speed regulation and starting of low-power geared motors are small. Stepless speed regulation is relatively expensive. The advantage is that the speed regulation is stable, suitable for various harsh environments, and the speed regulation range is small when the power is off. Stepless speed regulation is divided into mechanical speed regulation and electrical speed regulation. Electric speed regulation is suitable for asynchronous motor cascade speed regulation, rotor resistance speed regulation, DC motor voltage regulation and speed regulation, etc.
