The maximum torque of the BLDC motor: can be obtained by adding the load torque, the moment of inertia and the friction force, in addition, there are some additional factors that affect the maximum torque such as the resistance of the air gap air.
The BLDC motor is a type of synchronous motor, that is to say, the speed of the motor rotor is affected by the speed of the rotating magnetic field of the motor stator and the number of rotor poles (p):
The BLDC motor consists of a motor body and a driver, and is a typical mechatronic product. Brushless motor refers to a motor without brushes and commutators (or collector rings), also known as commutatorless motors. As early as the 19th century, when the motor was born, the practical motor produced was the brushless form, that is, the AC squirrel-cage asynchronous motor, which has been widely used.
