(Summary description)The manufacturer of Recorder play bldc motor tells you that a brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product.
Since the brushless DC motor operates in a self-controlled manner, it does not add an additional starting winding to the rotor like a synchronous motor with heavy load under variable frequency speed regulation, nor does it cause oscillation and out of step when the load changes suddenly.

The manufacturer of Recorder play bldc motor tells you that a brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product.
Since the brushless DC motor operates in a self-controlled manner, it does not add an additional starting winding to the rotor like a synchronous motor with heavy load under variable frequency speed regulation, nor does it cause oscillation and out of step when the load changes suddenly. The manufacturer of Recorder play bldc motor tells you that the permanent magnets of small and medium capacity brushless DC motors now mostly use rare earth neodymium iron boron (Nd-Fe-B) materials with high magnetic energy product. Therefore, the volume of the rare earth permanent magnet brushless motor is reduced by one frame size compared with the three-phase asynchronous motor with the same capacity.
working principle:
The manufacturer of Recorder play bldc motor tells you that a brushless DC motor is composed of a permanent magnet rotor, a multi-pole winding stator, and a position sensor. The position sensor commutates the current of the stator winding along a certain order according to the change of the rotor position (that is, detects the position of the rotor magnetic pole relative to the stator winding, and generates a position sensing signal at the determined position, which is processed by the signal conversion circuit To control the power switch circuit, switch the winding current according to a certain logic relationship). The manufacturer of Recorder play bldc motor tells you that the working voltage of the stator winding is provided by the electronic switch circuit controlled by the output of the position sensor.
