Types of AC Motor – Different Types of Motors – Electric Motor


An AC motor is an electric motor driven by
an alternating current. The AC motor commonly consists of two basic
parts, an outside stationary stator having coils supplied with alternating current to
produce a rotating magnetic field, and an inside rotor attached to the output shaft
producing a second rotating magnetic field. The rotor magnetic field may be produced by
permanent magnets, reluctance saliency, or DC or AC electrical windings. In this video we will go to learn Different
types of AC motors and their Uses. Electric motors are basically two types. One DC motor and another AC motor. DC motor classification we will describe in
another video, and this video link in Description below. AC motor is two types, 1. Synchronous motor, and 2. asynchronous motor. Asynchronous or induction motor is also two
types, Single phase motor, and three phase motor. Synchronous Motor:
These motors have the rotor rotating at the same speed as the speed of rotation of the
stator current. In other words, we can say these motors don’t
have slip with respect to the stator current. They are sometimes used no to drive the load
but instead act as “synchronous condenser”, to improve the power factor of the local grid
to which it is connected to. These kind of motors are used even in high
precision positioning devices like modern robots. They can also act as stepper motors. Asynchronous Motor:
The most common form of motor which is used in everyday life from pumping water up the
overhead tank to power plant boiler feed pumps. These motors are very flexible to use and
matches the load demand almost for everything. The most widely used Induction Motors are
very important for many industries due to their load bearing capacity and flexibility. They are generally used for various types
of pumps, compressors and acts as prime movers for many machineries. Single and Three Phase Motor: AC Motors can find their usage in two forms
based on their power supply. Single Phase Motor and Three Phase Motor. The single phase motors are generally found
their use in low power requirements or domestic appliances like ceiling fans, mixer grinders,
portable power tools etc. The three phase motors are generally found
for high power requirements like power drives for compressors, hydraulic pumps, air conditioning
compressors, irrigation pumps and many more. Dear sir, Thanks for watching the video. More update please subscribes our channel
