Electrical machine are devices that convert the mechanical energy to electrical energy or the other way, it also changes the alternating current from one level to another level. It can further be divided into three parts i.e. a motor, generator and transformer. There are various type of these electrical machines which are employed in industrial
An electrical machine is just a device that can either transform mechanical energy into electrical energy or vice versa. When such a device is used to convert mechanical energy to electrical energy, it is called a generator and the other way around When machines convert electrical energy into mechanical energy, it is termed a motor.
