What are the common types of DC motors

In a variety of electronic products, such as small household appliances, electric toys, smart homes, electronic door locks, etc., will be applied to the micro DC motor, different types of DC motors are different products, the current DC motor types on the market are very many, mainly divided into the following three types of stepper motor, permanent magnet DC motor and servo motor.

1. Stepper motor

The output shaft can be rotated at a precise Angle by applying the sequence pulse. As long as the appropriate sequence pulse is applied, the stepper motor can rotate continuously according to the predetermined speed or direction. It is only applied to products that require accurate measurement of angular rotation, such as robotic human arms and printer font control.

2. Permanent magnet DC motor（bldc pmsm motor）

This kind of DC motor is very common, can be divided into brush DC motor and brushless DC motor, by controlling the input DC voltage size can control the speed, in the robot, smart home, toys, adult products, electronic door locks and other fields of application is very much, brush DC motor control speed convenient advantages, but because of the friction between the brush and the commutator will lead to too short service life, Generally, the service life of the carbon brush motor is about 800 to 1000 hours, but it is completely suitable for household electric products. The friction life of the brushless DC motor without brush and commutator can reach tens of thousands of hours, but the price is generally about 2 times that of the brush motor, and the control is more complex, only some long-run electric products will use the brushless DC motor.

3. Servo motor（12v DC servo motor）

This kind of DC motor is characterized by controllable, when there is a control signal, the DC motor will rotate, the speed is proportional to the size of the voltage, remove the control signal voltage, the DC motor will immediately stop rotating, generally used in automatic control systems.

The above are several common types of DC motors. MAXTECH micro Motors focuses on the development, production and sales of micro motors and fan motors. For more information about micro motors and fan products, please continue to follow MAXTECH. We continue to explore and research new processes, looking forward to the production of advancing with The Times suitable for all kinds of household appliances supporting fans and motors.
