Abstract

The invention belongs to the field of motors and provides an axial-radial excitation permanent magnet brushless motor. The motor comprises a first axial rotor, a second axial rotor, a radial rotor and a stator component, the stator component comprises a fixing shaft, a radial stator support, a first axial stator, a second axial stator, a radial stator, a first folding winding and a second folding winding, the radial stator support is fixed on the fixing shaft, and the first axial stator, the second axial stator and the radial stator are fixed on the radial stator support. The first axial rotor and the second axial rotor are arranged at two ends of the fixing shaft in a penetrating mode and oppositely arranged, and permanent magnets are arranged in the rotors respectively. The first axial rotor, the second axial rotor and the radial rotor form an enclosed cavity, and the stator component is fixed on the fixing shaft in the enclosed cavity. By means of the axial-radial excitation permanent magnet brushless motor, the space in the motor can be utilized to the hilt, the magnetic field intensity distribution of the motor is improved, and thereby the efficiency of the motor is improved.

Description

technical field [0001] The invention relates to the field of electric motors, more specifically, relates to an axial radial excitation permanent magnet brushless electric motor. Background technique [0002] Axial radial excitation permanent magnet brushless motor is a kind of electromechanical energy conversion device, which is widely used in walking tools. The motors used in walking tools have their unique performance requirements: large starting torque, stepless speed regulation, small current, and power density. Big wait. Most of the walking industry requires high-precision constant-speed drive, and the requirements for low vibration and low noise are getting higher and higher; therefore, in addition to requiring the electromagnetic torque ripple generated by the motor current to be small, it is also required to reduce the permanent magnetic field and iron core. The magnetic reaction moment change produced by the structure is small. The structure of commonly used perma...
