Can the DC gear motor be adjusted in speed?

Release time: 2022-08-12

1. The DC geared motor produced by the DC geared motor manufacturer can adjust the speed. (If it is not a DC brushless motor), the DC geared motor is powered by a voltage-adjustable DC power supply, and the speed of the DC geared motor can be adjusted by adjusting the power supply voltage;

2. The deceleration and speed regulation of the DC gear motor are two different things. Speed regulation refers to changing the power supply voltage of the DC motor (or changing the drive circuit parameters of the DC motor) to achieve the purpose of adjusting the speed, while deceleration (in most cases) refers to installing a reducer with a certain speed ratio on the output shaft of the DC motor to achieve Slow down (and increase torque at the same time);

3. DC motor is divided into "brush motor" and "brushless motor". The former can achieve the purpose of adjustment by changing the supply voltage. The voltage of the latter's power supply must be constant (brushless DC motor cannot be changed by changing the power supply voltage. adjustment), but to achieve the adjustment purpose by adjusting the drive;

4. There are two types of drivers for brushless DC motors: built-in and external. Most of the built-in-driven brushless DC motors cannot be speed-regulated. Whether the external-driven brushless DC motor can be speed-regulated depends on the structure of the driver.

5. Magnetic DC motors, (mostly) are brushed motors. If the rated working voltage of the motor is 12V, a 0-12V DC regulated power supply can be used for stepless speed regulation of the motor.
