Brushless motor controller in domestic development time is shorter, and as the technology matures and perfect get rapid development. Has been in business, medical equipment, household appliances, communications products, robot, and other fields is widely used. Below I to introduce the composition of it. brushless dc motor controller is composed of main body of the motor and drive, a kind of typical electromechanical integration products, with three phase asynchronous motor is very similar. Stuck on the rotor of the motor, have already the magnetization of the permanent magnet, the stator winding of the motor to make more balanced three-phase y connection. In order to detect the polarity of the motor rotor, motor with position sensor. Drive consists of power electronic devices and integrated circuit, its function is to accept the motor start, stop, brake signal, to control the motor start, stop, and the brake; Accept the position sensor signals and positive &negative, used to control the inverter bridge on and off of each power tube produce continuous torque; Accept the speed instruction and speed feedback signal, which is used to control and adjust the speed; To provide protection and display, and so on. Because of brushless dc motor based on self-control type run so not as frequency control of motor speed under overloading starting of synchronous motor controller as plus start around on the rotor. Now many high rare earth ndfeb magnetic energy product (Nd-Fe-B）Materials. Therefore, medium and small capacity of the permanent magnet brushless dc motor (BLDCM). The volume of rare earth permanent magnet brushless motor is three-phase asynchronous motor with capacity reduces a frame number. For brushless dc motor controller has the characteristics of a dc motor controller, as well as the frequency change device, so also known as dc frequency conversion, the international general term for BLDC. MotorsIts running efficiency and precision of low speed torque and rotational speed is more good than any of the control technology of inverter, so the industry concern. in order to adapt to social development, the motor controller is devoted to the brushless motor controller of research and development, production and sales, if you want to know more products, please visit: http://www. hengdrive。 Com or email to: the sales @ hengdrive.
