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.

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...
