Midea Group has patented a counter-rotating motor for high-speed blenders. The motor includes a stator with outer and inner windings, an inverter for synchronous excitation, an inner rotor rotating in ...

3-phase BLDC motors are widely used in modern electronic devices such as hard, floppy and CD-ROM drives as well as other consumer and industrial equipment. BLDC motors have a straight-line, ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...

A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180°. But they are widely used to operate ...
