Title:
DISK-TYPE ELECTRIC MOTOR, ELECTRICALLY DRIVEN VEHICLE AND METHOD FOR CONTROLLING THE SAME
Document Type and Number:
WIPO Patent Application WO/2017/140245
Kind Code:
A1
Abstract:
A disk-type brushless direct current (BLDC) motor comprises a magnetic rotor (202) and a stator (201). The magnetic rotor (202) is provided with a rim (212) and a plurality of equally spaced magnetic poles around the rim (212) in circumferential direction. The stator (201) is provided with a stator core (310) having tooth portions (1221) and boot portions (1222) and a plurality of coil windings (309) wrapped around the tooth portions (1221). The stator (201) is disposed radially in relation to the magnetic rotor (202) such that the magnetic poles are radially polarized to produce radial magnetic flux density, and the magnetic flux density is substantially higher at both edges than middle portion of each magnetic pole in the circumferential direction.
