How many different types of micro DC motors are there?

Micro DC motors are used in various fields, such as household appliances, smart homes, electronic door locks, beauty instrument products, etc. Different types of coreless DC motors are used for different applications: vibration motors are used for massage functions, and micro gear motors are required for heavy loads. Besides vibration motors and gear motors, what other types of micro DC motors are there? WKX MOTOR will give you a brief introduction to several different types of DC motors.

DC motors can be broadly divided into four categories: Permanent Magnet Commutated DC Motors, Servo Motors, Two-Phase Low-Voltage Motors, and Stepper Motors.

1. Permanent Magnet Commutated DC Motors These are essentially the Brushed DC Motors. Their design is very simple, and they are widely used in products such as electronic locks, electric toys, robots, and beauty instruments. They can also be used in drive devices with a wide speed range, such as toy racing cars and model aircraft. With the help of electronic control circuits, the performance of micro motors can be greatly enhanced.

2. Servo Motors The biggest characteristic of a servo motor is its controllability. It acts as an executive component in automatic devices. The motor rotates only when there is a control signal, and the speed is proportional to the small control voltage. If the control signal voltage is lost, the servo motor will stop rotating immediately. Servo motors are also widely used, being applied in almost all automatic control systems.

3. Stepper Motors By applying an appropriate sequence of electrical pulses, a stepper motor allows the micro motor spindle to rotate by a precise angle. As long as the appropriate pulse sequence is applied, the micro motor can rotate continuously at a predetermined speed or direction. Stepper motors use a microprocessor or integrated driver circuit; they are easy to control and are generally used in fields that require precise angular rotation measurement, such as robotic arm movement, or printer head control.

4. Two-Phase Low-Voltage Motors These motors usually involve a DC power supply feeding a low-frequency oscillator, which then drives the motor at low frequency and low voltage. This type of motor is occasionally used in turntable drives.
