VI. Frequently Asked Questions on Electric Motors
A. What is the difference between AC and DC Motors?
The main difference between AC (Alternating Current) and DC (Direct Current) Motors is the way in which the electrical power is supplied to the motor.
DC motors operate using a constant supply of electrical power with the same polarity. In contrast, AC motors require a fluctuating alternating electrical current to operate.
AC motors are generally more efficient and reliable than DC motors, and they are the most commonly used type of electric motor.
B. What are 'stator windings'?
Stator windings are one of the key components in an electric motor, and they are responsible for producing the magnetic field that drives the motor.
They are electrical coils wound around the stationary part of an electric motor, known as the stator, and are made from copper wire.
When electrical current passes through the stator windings, it creates a magnetic field that interacts with the magnetic field produced by the rotor to turn the motor.
C. What are three phase induction motors?
Three-phase induction motors are a type of AC motor that is widely used in industrial and commercial applications.
They are highly efficient, durable, and reliable, and are capable of producing a large amount of power for extended periods of time.
Three-phase induction motors use a rotating magnetic field produced by three-phase electrical power to turn the rotor and generate mechanical power.
D. What is the difference between squirrel cage and slip ring motors?
Squirrel cage and slip ring motors are two different types of three-phase induction motors. Squirrel cage motors are the most common type and have a simple design that does not require any extra components such as brushes or slip rings.
They are highly efficient and reliable and are used in a wide range of applications.
Slip ring motors, on the other hand, have a more complex design that allows for better speed control and starting torque.
They use slip rings and brushes to connect the rotor winding to an external electrical circuit, which allows for external resistance to be added or removed to control the motor's speed and torque.
They are commonly used in heavy-duty applications such as cranes, hoists, and elevators.
