Analysis of a brushless dc motor integrated with a high-pressure vane pump
Languages of publication
A new design of a brushless direct current motor is introduced in this paper. In the BLDC motor, a high-pressure vane pump is built into the rotor. The motor is excited by neodymium magnets. Its nominal power is 2.5 kW. The motor is built in such a way that the magnetic field does not penetrate the pump. A magnetic structure field analysis of the motor was performed. Demagnetization resistance of the magnets was determined. By the use of time stepping, finite element method waveforms of the electrical and mechanical parameters in the BLDC motor–inverter system were determined.
