Electric motors convert electrical energy into mechanical energy. They operate on electromagnetic principles, typically with a stationary stator that produces a magnetic field and a rotating rotor that turns a shaft. The interaction between the stator field and the rotor's windings or magnets generates torque, enabling motion and energy transfer to machinery.
Common types include alternating-current AC motors (induction and synchronous) and direct-current DC motors (brushed and brushless).
Typical components are the stator, rotor, windings or magnets, bearings, and housing. Brushed DC motors incorporate
Performance is controlled by voltage, current, or frequency. For AC motors, variable-frequency drives VFDs adjust speed
Electric motors are foundational to modern machinery, powering pumps, fans, conveyors, appliances, robotics, and electric vehicles.
