Explanation:right on edge
The direction of rotation of a motor be changed by reversing two of its stator leads.
Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy. In other words, the devices which produce rotational force is known as the motor.
In order to reverse the direction of an AC motor, we need to change the magnetic field the to make the movement in the opposite direction. As we change the direction of magnetic field , force will also get reversed by using Fleming's left hand rule .
Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation
Hence, the direction of rotation of a 3-phase motor can be changed by reversing two of its stator leads.
