What Is Dc Motors? |
|
Answer» A DC motor is a mechanically commutated electric motor powered from DIRECT CURRENT (DC). The stator is stationary in space by DEFINITION and therefore so is its current. The current in the rotor is SWITCHED by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained NEAR 90 degrees, which generates the maximum torque.
