AC machines can be further classified as Induction machines and Synchronous machines.And hence, AC generators as Synchronous generators (commonly referred as alternators) and Induction generators (or asynchronous generators). There is significant difference between operating principles of synchronous and induction machines.

Synchronous Motors For the Paper Industry WEG Electric Machinery, WEM, synchronous motors incorporate special features making them the right choice for use in the corrosive environments found in paper mills. Rotor Rotor Construction The rotor consists of a spider on which the field poles, amortisseur (cage) windings and brushless
Our rugged high voltage IEC synchronous motors are used in a wide variety of applications, which call for the highest power and torques capabilities, as well as a maximum plant availability. In applications such as central gas compressor stations, blast furnaces, rolling mills or ore mills.
A synchronous generator is essentially the same machine as a synchronous motor. The magnetic field of the rotor is supplied by direct current or permanent magnets. The output frequency of an asynchronous generator is slightly (usually about 2 or 3%) lower than the frequency calculated from f …

Nov 15, 2015· In a motor, synchronous speed is the speed at which the magnetic field rotates. Depending on motor design, the actual mechanical speed may be equivalent (synchronous motor) or slightly smaller (asynchronous motor).The synchronous speed is a function of: The electrical frequency used, typically 60 Hz or 50 Hz.

Here's a typical synchronous motor application - a ball mill in a mine ore process: I see these from about 500Hp to about 8,000Hp with synchronous speeds of 120 to maybe 400RPM. Synchronous motors are also used in paper mills, refineries and numerous other applications. Often they are …
On the other hand, asynchronous motors are excellent for speeds above 600 rpm. Unlike asynchronous motors, synchronous motors can be run at ultra-low speeds by using high power electronic converters which generate very low frequencies. They can be used to drive crushers, rotary kilns and variable speed ball mills.

The detail explanation of the Difference Between Synchronous and Asynchronous Motor is given below. Synchronous motor is a machine whose rotor speed and the speed of the stator magnetic field is equal. Asynchronous motor is a machine whose rotor rotates at the speed less than the synchronous …
Originally Answered: Why is the induction motor called an asynchronous motor? There are basically 2 types of induction motors - synchronous and asynchronous. The synchronous induction motor always runs at synchronous speed (with DC field pole windings in the rotor) determinedby no. of poles in the rotor windings.
