Abstract
The invention pertains to synchronous machines with permanent magnets. The machine proposed consists of the rotor 1, where permanent magnets from ferrite barium or ferrite strontium are fixed. Ferrite barium and ferrite strontium are inexpensive, but reliable materials for permanent magnets. The ends of magnets are distanced by nonmagnetic wedges 4 and 5 to an optimum distance with the purpose of receiving of maximum magnetic flux.....The same value is a slot opening width. Variables ... and hm represent here an air gap value and hight of magnets. Three phase winding 9 is arranged in the slot 7 of the stator 8, which is separated from the rotor 1 by the air gap 10. For example, synchronous machine as the motor operates as follows. In case the winding 9 is supplied by three phase current, there appears rotating magnetic field, which interacting with magnets 2 and 3, causes rotation of rotor 1. Advanced poles (magnets) increase the magnetic flux, therefore, torque and power density are also increased, while distribution of the windings, shortening pitch and beveling of stator slots reduce the amplitude of higher harmonics of the magnetic field, hence the vibration is reduced too.
