Question

Most of the electromagnetic energy conversion devices belong to
o
singly excited magnetic systems
doubly excited magnetic systems
multiply excited magnetic systems
O both doubly excited magnetic systems and multiply excited magnetic systems​

Answer 1

Answer:

Electromechanical energy conversion theory is the cornerstone for the analysis of electromechanical motion devices. – The theory allows us to express the electromagnetic force or torque in terms of the device variables such as the currents and the displacement of the mechanical system.

Answer 2

Answer:

Numerous practical applications need for multiply excited magnetic systems, including the widely utilised synchronous and induction machines, which belong to doubly excited systems.

An electromechanical power conversion device is one that transforms mechanical power into electrical power or electrical energy in mechanical energy. Devices that move in a grotesque manner, like electrical motors and generators.

Explanation:

Because the magnetic field has a far higher energy storage capacity than the electric field, it is typically used as coupling medium among electrical and mechanical medium.

An electromechanical energy conversion technique known as singly-excitation uses only one coil that produce the magnetic field.
