sew motors consist of the motor body and the driver, representing a typical mechatronic product. Brushless motors refer to motors without brushes and commutators (or slip rings), also known as commutator-less motors. As early as the nineteenth century, when motors were first invented, the practical motors produced were of the brushless type, namely AC squirrel-cage asynchronous motors, which were widely used. However, asynchronous motors have many insurmountable drawbacks, resulting in slow development of motor technology. Transistors emerged in the mid-twentieth century, leading to the use of transistor commutation circuits to replace brushes and commutators.
