In this paper, according to the control requirements of the claw pole motor with PM outer rotor, a sensorless motor controller was designed based on ML4425 and PIC16F877A. Based on Matlab/Simulink, mathematical model and control system model of the motor were established. A pure hardware motor controller was designed. The controller includes a regulated power supply, ML4425 external circuit, PIC16F877A...
An axial sectional claw pole high speed square wave motor with permanent magnet outer rotor was proposed and designed which was applied in axial air compressor group to realize direct drive. Firstly, according to the core loss in high speed motor is greater, a new calculation model was built to compute core loss accurately by a way of equivalent substitution three orthogonal alternation magnetization...
Due to surface-mounted permanent magnet (PM) high speed synchronous machines need a glass or carbon-fiber bandage to fasten the magnets to the rotor surface, which increase equivalent air-gap length and decreases efficiency of heat dissipation, so a claw pole motor with outer PM rotor is presented, which is without bandage. The design process of this motor for high speed application is introduced,...
The double wishbone suspension and steering system were regarded as a whole system, then its multi-body model and array of lower serial number objects were established based on multi-method physical science in Kane. Kinematical equations and constraint equations of this system were set up, providing a genetic algorithm using the MATLAB toolbox for solving exactly constraint equation approach. Based...
