Is synchronous motor and generator same?
Similarly, the terms “stator windings” and “armature windings” are used interchangeably. The rotor of a synchronous generator is essentially a large electromagnet….Construction of a synchronous generator.

Can we use synchronous motor as alternator?
Synchronous motor and induction motor are the most widely used types of AC motor. A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.
Why Starting is not easier for a synchronous motor?
Above a certain size, synchronous motors are not self-starting motors. This property is due to the inertia of the rotor; it cannot instantly follow the rotation of the magnetic field of the stator. Once the rotor nears the synchronous speed, the field winding is excited, and the motor pulls into synchronization.
How does a synchronous generator work?
Assuming it is connected to the power system, the synchronous generator can draw excitation from the DC field or through the armature winding. So, like the synchronous motor, it can operate at leading or lagging power factors, which enables it to provide reactive power to inductive loads in the power system.
What are the applications of synchronous motors?
Synchronous motors are usually used where there is a need for precise and constant speed. Low power applications of these motors include positioning machines. This kind of electric motors is also applied in robot actuators. Some other applications make use of synchronous motors such as ball mills, clocks, and record player turntables.
What are motmotors and generators?
Motors and generators are the indispensable parts of the electrical system that we use either in industries such as power stations, or for domestic applications. The requirement for electrical systems producing high energy and consuming less power, the invention of new models of these electrical devices is seen.
What is a permanent magnet synchronous motor?
For the design of Permanent magnet synchronous motors, a permanent magnet is used along with steel. They have a constant magnetic field in the rotor, so induction winding cannot be used for starting. Being used as gearless elevator motors. The rotor of the reluctance motor is made up of steel casting with poles of projecting tooted.
