Based on Ansoft computational tools, using finite element numerical method analytical the leakage magnetic field of asynchronous motor with closed rotor slots and bilateral closed slots, obtain the numerical relationship between slot structure and leakage reactance parameters. Propose a improve method for magnetic circuit calculation of closed slot motor.
Using the multi-objective hybrid simulated annealing algorithm, this paper optimal design the three-phase induction motor. Typical examples of optimization show the efficiency and feasibility of this method.
In view of improving control capability, a current controller of the permanent magnet spherical stepper motor was designed in this paper. Adaptive and switching control algorithms assured the rotor to drive mechanical loads following the continuous path motion and alleviating the tracking errors. Current-tracking PWM technology was applied in the controller. Simulation and experiment results show...
