Abstract:
Below a predetermined threshold value of the rotation speed, a sinusoidal or trapezoidal current is applied to the winding sections of a brushless DC motor. Above the predetermined threshold value of the rotation speed, the brushless DC motor is operated with block commutation. The brushless DC motor thus produces a very uniform torque over a very wide operating range, and can at the same time be designed to be very compact.
