AC vs DC Brushless Servo Motor By John Mazurkiewicz, Baldor Electric Brushless motors are similar to AC motors since a moving magnet field causes rotor movement. Brushless motors are also similar to PM DC motors since they have predicable linear characteristics. Is this why the brushless is sometimes called AC brushless and sometimes called DC From an operating standpoint, DC motors generate more torque (starting power), so it is not unusual for a DC electric car to have no transmission---another cost-cutting aspect. And brushless DC motors generate less heat than an AC induction motor, meaning less energy is wasted.

(current vs. torque proportion). • The motor is controlled by applying a voltage to the motor leads. The higher the voltage, the higher the speed. The direction is changed by reversing the polarity on the leads. • The maximum torque is limited by the current rating of the motor and it … Let’s move on to induction motor drives. A forerunner of the 3-phase induction motor was invented by Nikola Tesla sometime before 1889. Curiously, the stators for the 3-phase induction motor and the DC brushless motor are virtually identical. Both have three sets of “distributed windings” that are inserted within the stator core.
