Electromagnetic phenomena analysis in brushless DC motor with speed control using PWM method

open access: yesOpen Physics, 2017
Field-circuit model of a brushless DC motor with speed control using PWM method was developed. Waveforms of electrical and mechanical quantities of the designed motor with a high pressure vane pump built in a rotor of the motor were computed. Analysis of

Optimization of PM Slotless Brushless DC Motors Considering Magnetic Saturation and Temperature Limitation

open access: yesEnergies
When magnetic saturation occurs during the operation of a permanent magnet (PM) slotless brushless DC motor, the material permeability will no longer be a constant value, and the neglected magnetic saturation model used for motor optimization will no ...

Control motor brushless sensorless

open access: yes, 2015
The project involves the creation of a speed controller circuit for a brushless sensorless motor. The caracteristic factor of this type of electric motors is that they don't have brush to change the polarity of the windings and they have no sensors to know the real position of the rotor.
