Brushless motors can offer impressive torque-to-size ratios, and when combined with complex drive control and sensor feedback, exciting things become possible that expand the usual ideas of what ...

The trickiest part was designing a speed control mechanism for the brushless motor—an impressively solved puzzle. After some serious elbow grease and ingenuity, the franken-drill emerged better ...

Three-phase brushless motors offer many benefits including economy, reliability and high efficiency, but also exhibit poor dynamic performance. By implementing proper control algorithms (such as field ...

BLDC motors are often specified to maximize efficiency and torque density, and open rotor designs can further extend these capabilities.

as well as electronically driven brushless motors. We will discuss shunt wound, series wound, compound wound, servo, stepper, and torque motors, with a detailed explanation of how commutation and ...
