AXIAL TYPE ELECTRIC MACHINE WITH PERMANENT MAGNETS
The development of new technique and technology puts forward new requirements for electrical machines, which vary depending on their area of application. Among them, the most important ones can be distinguished, namely: increasing the speed control range; increase in dynamic performance by increasing the achieved acceleration; increasing the specific electromagnetic moment; reduction of electromechanical
ELECTRICAL MACHINES WITHOUT EXCITATION WINDINGS AND PERMANENT MAGNETS
Modern electrical machines (direct-current machines, synchronous machines, alternating-current converter-fed motors, universal commutator motors, and other electrical machines) contain two windings, that is, an excitation winding and an armature winding (in direct-current machines) or a stator winding (in synchronous machines and alternating-current converter-fed motors).
