Micro DC motors are used in major fields, such as household appliances, smart homes, electronic door locks, beauty device products, etc., different applications will use different types of DC motors, vibration motors will be used when massage functions are required, and micro gear reduction motors are needed to drive larger loads. In addition to vibration motors and geared motors, what other types of micro DC motors are there? The following Tianfu micromotor briefly describes several different types of DC motors.
DC motors can be roughly divided into four categories, permanent magnet converter DC motors, servo motors, two-phase low-voltage motors, and stepper motors.
1) Permanent magnet converter DC motor
That is, brushed DC motor, its design is very simple and widely used, such as electronic locks, electric toys, robots, beauty instruments and other products will be applied to, when the micromotor applies rated DC voltage, the speed is equal, some fixed speed electronic products can be encountered, can also be used for a wide range of variable speed drive devices, such as toy racing cars, model aircraft, etc., it with the help of electronic control circuit role, can make the performance of micro-motor greatly enhanced.
2) Servo motor
The biggest feature of servo motor is controllability, it is an automatic device in the executive element, only in the control model of the motor can rotate, the speed in small and proportional to the control voltage, such as the loss of control signal voltage, servo motor will immediately stop rotating, servo motor application is also very extensive, almost all automatic control systems will be applied.
3) Stepper motor
Stepper motor plus appropriate sequence pulse can make the micro motor spindle rotate a precision angle, as long as the appropriate pulse train, the micro motor can rotate continuously according to the predetermined speed or direction, stepper motor with microprocessor or drive integrated circuit, easy to control, generally used in the field of accurate measurement of angle rotation, such as robot arm movement, printer head control, etc.
4) Two-phase low voltage motor
This type of motor is usually supplied with a DC power supply to a low-frequency oscillator, and then the low-frequency low-voltage motor is driven. These motors are also occasionally used in turntable drive mechanisms.
The above is the introduction of several different types of micro DC motors, for more information about micro DC motors, please continue to pay attention to Tianfu Micro Motors.
