DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

Both the brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) require electronic commutation in order to create a rotating electromagnetic field, which is needed to turn the rotor. Both ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

The transient performance and frequency stability of hysteretic-based synchronous DC-DC converter ICs can be improved with ramp control and adaptive on-time techniques. The control method used in a ...
