Purpose and classification of electrical machines.
Electrical machines are divided into generators, which convert mechanical energy into electrical energy; electric motors that convert electrical energy into mechanical energy, as well as special machines that most often convert electrical energy of one type into electrical energy of another type.

According to their design, electric machines can be either brushed or brushless. Collector machines are most often used to work on DC both as generators and as electric motors. They are used less often on alternating current, mainly as single-phase electric motors relatively low power. Brushless electric machines operate almost exclusively on alternating current. Based on their operating principle, they are divided into asynchronous, used mainly as electric motors, and synchronous, used as generators or electric motors.

Electric machines are widely used in all sectors of the national economy, where there are a wide variety of working conditions and different requirements. In this regard, electric machines of many types have been developed and are produced by industry. designs; with horizontal and vertical arrangement shaft, foot or flange mounted, with different ways cooling systems, for example blown with air only from the outside or blown also inside, with varying degrees of protection against influence external environment- open and protected versions, splash-proof, waterproof, explosion-proof, sealed, etc.
