The Brushless DC Electric Motor, also know as Electronically Commutated Motors, are made by the MICROMO Engineering Company, who are located in Clearwater, Florida.

To state it simply, a DC brushless motor is not a DC motor.

It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.

Many stores sell the Brushless DC motor. Among them are Robot Shop, Maxon Motor, and Ted Motors. It would be expected that other mechanically oriented stores would sell Brushless DC motors too.

A stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. It moves one step at a time.

actually dc motors are of several types in which one of them are 1).brushed 2).brushless ...so the motor present in DVD are the brushless dc motors ...
