Which is the best China small 12v dc motor manufacturer? Of course teamwork grobal group limited.
DC motor is a motor that converts DC energy into mechanical energy.It is widely used in power drag because of its good speed regulation performance.The DC motor is divided into three categories: permanent magnet, other excitation and self-excitation, among which the self-excitation is divided into parallel excitation, string excitation and reexcitation. Determinant of motor speed: For the synchronous motor or asynchronous motor, the speed of the motor is related to the frequency of the power supply, the magnetic pole log of the motor, the higher the power supply frequency, the less the log of the magnetic pole, the higher the speed; for the asynchronous motor is also related to the current through the electric coil, the greater the current, the speed is closer to the synchronous speed.There is also a type of motors (usually AC-DC motors) whose speed is independent of the frequency of the power supply.Only related to the size of the current passing through the coil.
