Reduction in power consumed by motors is required for energy saving in electrical appliances and electric vehicles. The motors used in such appliances and vehicles operate at variable speeds. For reducing energy consumption of electrical appliances, the flux-weakening current that depresses the voltage at high speed leads to significant copper and core losses. Therefore, we have developed a new technique...

A hybrid vehicle (HEV) is one of the solutions to improve efficiency of a cruse and to reduce CO2 gas. It is requested to decrease the motor size and to increase the maximum torque for minimizing the driving units. For these purposes permanent magnet applied motors have been commonly used recently. And according to electrical output up rating of a hybrid electric vehicle motor, parallel circuits will...
Reduction of electrical consumption of a electric vehicle (EV) and electrical appliance is one of solutions for reduction of CO2 gas. Then, we have developed a novel permanent magnet motor for energy saving. In this paper, we propose a novel motor that can change magnetic flux by a new method magnetizing a permanent magnet and clarify the principle and unique characteristics. Furthermore, the results...

This paper describes the development of a basic permanent magnet disc motor (PMDM) simulation model for MATLAB/SIMULINK transient analysis. The PMDM model consists of SIMULINK blocks that can be easily implemented in a real-time test environment in order to investigate all different transient regimes of the motor. The simulation drive model is consisted of a PMDM model and a pulse width modulated...
