The invention relates to a dual-control double-drive permanent-magnet direct-current brushless motor, comprising a rotor and a stator, thirty-six armature poles are arranged on the stator, and 360 degrees of circumference of the armature poles is equally divided into four parts, and each part includes nine armature poles, thirty-two permanent magnet steels, corresponding to the stator, are arranged on the rotor, and 360 degrees of circumference of the permanent magnet steels is equally divided into four parts, and each part includes eight permanent magnet steels, eighteen armature poles are added in each 90 degrees of opposite angle, sixteen permanent magnet steels are added, and eighteen armature poles, added in each 90 degrees of opposite angle, are taken as one group of three-phase windings, and two groups of the three-phase windings are arranged in the 360 degrees of circumference. Compared with the motor with the same volume, the motor in the invention has large output torque, low heat value and high energy conversion efficiency, thereby solving the technology bottleneck of a heavy current control system of a high-power permanent-magnet brushless motor.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a permanent magnet DC brushless motor capable of realizing dual control and dual drives. Background technique [0002] The permanent magnet brushless DC motor uses the cutting of the permanent magnet constant magnetic field and the electromagnetic variable magnetic field, and the control commutation system composed of the magnetic induction sensor to collect the signal of the permanent magnet and electronic components through the electromagnetic field A, B, C three-phase exchange power supply. It is a key component of electric vehicles such as electric cars and electric bicycles to realize its operation. However, the commutation conditions of the permanent magnet constant magnetic field and the electromagnetic variable magnetic field of the permanent magnet brushless DC motors currently on the market are not sufficient. Large, noisy, and the motor is prone to heat loss and energy...
