Title:
ELECTRICAL MACHINE WITH CLAW POLES
Document Type and Number:
WIPO Patent Application WO/2018/009987
Kind Code:
A3
Abstract:
The machine is designed for operation as alternator and motor alternator for motor vehicles, as electric motor for electric-driven vehicles, as servomotors and electric motor for two-zone regulation of rotational speed. It provides synergistic control of the magnetic flux, of the current output at operation as a generator, of the rotational speed when operating as an electric motor, by adjusting of the excitation electric current, and improved protection of permanent magnets from heat, increased power and current output. Between neighboring sides of at least two diametrically located pairs adjacent claw poles of the carrying and carried pole configurations geometric spaces are shaped in which permanent magnets (8, 8 ', 8") are stuck having a geometric shape of their cross-section corresponding to the shape of the geometric spaces. The ratio of the smaller width of the claw poles (6, 6 'and 6") and (7, 7', 7") to the larger width is not less than 0.5.
