The correct answer is Electric motor. Explanation & Key Takeaways: • Electric motor • An electrical motor converts electrical energy into mechanical energy. • An electrical motor works on the principle of electromagnetic induction. • Types of the electric motor: • AC motor: It converts alternating current into mechanical power. • DC motor: It converts direct current into mechanical power. Related Concepts: • A simple motor has the following parts: • Power supply: DC for a simple motor. • Field Magnet: Could be a permanent magnet or an electromagnet • Commutator: It is the rotating interface of the armature coil with a stationary circuit. • Field Magnet: The magnetic field helps to produce a torque on the rotating armature coil by virtue of Fleming’s left-hand rule. • Armature Core: Holds the armature coil in place and provides mechanical support. • Armature Coil: It helps the motor to run. • Brushes: It is a device that conducts current between stationary wires and moving parts, most commonly the rotating shaft. • Uses of an Electric Motor • Drill machine, Water Pumps, Hard Disc Drives, Washing Machines, Industrial Equipment etc.
