Synchronous generator

Synchronous machines are used in many sectors of the national economy, in particular, as generators in mobile and stationary power plants, motors in installations that do not require speed control or need a constant rotational speed.

The most common design scheme is a synchronous machine with a rotating rotor on which there are pronounced poles. Sometimes low-power explicit pole synchronous machines are made according to the design scheme of DC machines, that is, with poles located on the stator, the collector is replaced by slip rings.

Synchronous motors of the SD2 series and generators of the SG2 series are manufactured with a capacity of 132 to 1000 kW, with a rotation axis height of up to 450 mm, in a protected version IP23, with self-ventilation IC01, with a rotational speed from 500 to 1500 rpm.

Electric machines of the SD2 and SG2 series are designed for continuous operation. They are excited by a device powered by an additional winding embedded in the stator grooves.
