Course facilitator session on Understanding the Operation of Synchronous Motors
Synchronous motors play a crucial role in various industrial applications, offering precise control and efficient operation. Dr. S Gowrishankar, a distinguished professor at NIT Puducherry, recently shared invaluable insights into the functioning of synchronous motors during our course facilitator program.
One of the fundamental aspects Dr. Gowrishankar highlighted is the reason behind the inability of synchronous motors to self-start. Unlike induction motors, which can self-start due to the rotating magnetic field induced by the stator, synchronous motors require external assistance. This necessity arises because they are powered by three-phase AC supply, leading to a fluctuating magnetic field in the stator.
To overcome this limitation, a stable magnetic field is essential in the rotor. This stability is achieved by providing a DC supply to the rotor. However, to reach the synchronous speed, an external DC motor is employed to rotate the rotor initially.
Understanding this principle is critical for engineers and technicians working with synchronous motors. By ensuring a clear grasp of the interaction between the stator's AC supply and the rotor's DC supply, optimal performance and efficiency can be achieved in synchronous motor applications.
Dr. Gowrishankar's guidance sheds light on the intricate workings of synchronous motors, empowering professionals to leverage their capabilities effectively in diverse industrial settings.
