Abstract
Description
Technical Field
[0001] The present invention relates to a DC rotating motor, and in particular to a brushless DC rotating motor and a vehicle including the brushless DC rotating motor. Background Art
[0002] The traditional DC motor (DC Motor-Dynamo) is equipped with a commutator (commutator) structure to maintain the rotor magnetic field and the stator magnetic field in an orthogonal direction during the rotation process, so as to obtain the maximum torque at any time. At the same time, the DC motor has the simple property that the voltage is proportional to the speed, and the control is naturally simple, which makes it always occupy an important position in the traditional speed control, servo control and other fields. The DC motor (BLDC Motor-Dynamo) popular in the market today has a structure similar to that of a permanent magnet variable frequency synchronous rotating motor. It mainly uses the multi-phase magnetic field angle to alternately increase and decrease to form a rotatable angle, such as a three-phase magnetic field with a 120-degree angle, and a rotating magnetic field with a variable speed to drive the permanent magnet rotor, or to extract the AC power from the electromotive force induced by the rotating permanent magnet rotor through a multi-phase coil induction. Although this method is mature, its VVVF control method is quite complicated and unnatural. Therefore, it is still necessary to seek a commutatorless DC motor with a simple electromechanical structure, a simple driving mode, and better control performance than the traditional DC motor.
