What is the primary purpose of an electric motor?

The primary purpose of an electric motor is to convert electrical energy into mechanical energy. This conversion is essential for powering a wide range of devices and machines, from household appliances to industrial equipment. When electrical current flows through the motor's windings, it generates a magnetic field that interacts with permanent magnets or other coils, causing the rotor to spin. This rotational motion is what we refer to as mechanical energy, and it can then be harnessed to perform work, such as turning a fan blade, driving a conveyor belt, or moving a vehicle.

Understanding the role of an electric motor is crucial in various applications, particularly in industries where automation and precision are required. Applications span from small-scale devices like electric toothbrushes to large machines like electric cranes, illustrating the significance of this conversion process in our daily and industrial lives.
