Question

Difference between ac induction motor and vfd induction motor

Answer 1

Answer:

AC induction motors can be used without a VFD to drive a pump or fan, but are often installed with variable frequency drives (VFD) in pump systems or fan systems in an effort to improve system efficiency. Permanent magnet synchronous motors require a drive to operate. PMSMs cannot run without a drive.

Answer 2

Answer:

Explanation:

If the number of magnetic lines of force passing

through the coil changes, current is induced in the

coil. This is known as Faraday’s law of induction.

The current produced in the coil is called the

induced current.
