What is the inverse construction of a synchronous machine ...

As I understand - there is no “inverse construction” of a synchronous “machine”. In electrical science and engineering, a synchronous machine is a motor. Synchronous motors, or machines, are chosen for their constant torque / speed and along with induction motors, are the most - 85 %

Permanent Magnet Synchronous Machines

Synchronous Reluctance Machines. Synchronous reluctance machines make use of a reluctance rotor design but use a standard 3-phase ac winding. An induction cage on the rotor provides start torque, but once the machine is close to synchronous speed, the reluctance torque will synchronise the machine with the supply.

Construction and Types of Synchronous Machine | Electrical ...

Synchronous Machine is electromechanical equipment in which the speed of rotating part i.e., Rotor, is equal to the speed of rotation of magnetic flux. The speed of rotation of magnetic flux is called synchronous speed. That is why these types of equipment is called synchronous machine. This article outlines the constructional detail and type ...

Synchronous Motor Construction

Bearings on synchronous machinery are anti-friction, grease, or oil-lubricated on smaller machines, journal type oil-lubricated on large machines, and tilt-pad type on more sophisticated machines, especially where rotor dynamics are critical. Successful performance of magnetic bearings, proving to be successful on turbo-machinery, may also come to be used on synchronous machinery as well.
