Permanent magnet DC motors, often known as PMDC motors, are a subtype of DC motor that employs permanent magnets rather than electromagnets in the rotor. By interacting magnetic fields, they transform electrical energy into mechanical energy. High efficiency, small size, and accurate speed control are all features of PMDC motors. They are frequently utilised in situations where a small, light, and effective motor is needed, such as in robotics, electric cars, small appliances, and industrial automation. PMDC motors are renowned for their slick performance, low maintenance requirements, and strong starting torque.
