Electric Motor Tutorial - VintageMachinery.org

These motors can be explained best by referring to the series motor shown in figure 17, A, in which the same current flows through the rotor (armature) as the stator (field). This current flows into the motor from the external circuit. If the voltage applied to the motor is reversed, the current in both the armature and the field is reversed. The reversal of current in both parts of the motor

How does soft start work? - Motor Soft

How does soft start work? A soft starter is any device which controls the acceleration of an electric motor by means of controlling the applied voltage. An Induction motor has the ability to self start owing to the interaction between the rotating magnetic field flux and the rotor winding flux, causing a high rotor current as torque is increased. As a result the stator draws high

DC Motors Explained: Brushed vs Brushless

Typical brushless DC motors use one or more permanent magnets in the rotor and electromagnets on the motor housing for the stator. A motor controller converts DC to AC. This design is mechanically simpler than that of brushed motors because it eliminates the complication of transferring power from outside the motor to the spinning rotor. The motor controller can sense the rotor's position
