An electric motor performs the conversion of electrical energy into mechanical energy. This transformation is vital for the operation of various devices, from household appliances to industrial machinery.
When an electric current passes through the motor’s windings, it generates a magnetic field. This field interacts with permanent magnets or other magnetic fields within the motor, causing the rotor (the part that rotates) to turn. As a result, the electrical energy supplied to the motor is transformed into kinetic energy, which produces mechanical motion.
This principle is central to how electric motors function, making them essential components in numerous applications, from powering fans and electric vehicles to serving as actuators in robotics.
