position and speed control of brushless dc motors using

jul 19 on the other hand the u s a has kept on using cheap induction motor drives which have around 10 lower efficiency than adjustable pm motor drives for however the pm bldc motors are inherently electronically controlled and require rotor position information for proper commutation of currents in its

what is commutation and how does it affect linear motor performance?

aug 8 in brushless motors because there is no fixed reference the first thing a control or amplifier must determine is which phase needs to be energized state is detected in the digital hall signal the incremental encoder signals can then be used to digitally determine where in the commutation cycle the motor
