Export China bldc motor, quality assurance, welcome customers custom design.Brushless DC motor is composed of motor body and driver, which is a typical brushless DC motor of mechatronics.The stator windings of the motor are mostly made of three - phase symmetric star connection, which is very similar to three - phase asynchronous motor.A magnetized permanent magnet is attached to the rotor of the motor. In order to detect the polarity of the rotor, a position sensor is installed in the motor.The driver is composed of power electronic devices and integrated circuits, etc. Its functions are: to accept the start, stop and brake signals of the motor to control the start, stop and brake of the motor;It receives position sensor signals and positive and negative rotation signals, which are used to control on and off of each power tube of the inverter bridge and generate continuous torque.Accept speed instruction and speed feedback signal, used to control and adjust the speed;Provide protection, display, and so on.
In addition, many microprocessors have made the necessary functions of controlling the motor into the chip, and the volume is getting smaller and smaller.Like analog-to-digital Converter (ADC), Pulse wide Modulator (PWM)...And so on.Brushless DC motor (BLDCM) is an application that electronically controls the commutation of ac motors to obtain similar dc motor characteristics without the absence of DC motor mechanism.
