THREE-PHASE DC MOTOR
Document Type and Number:
WIPO Patent Application WO/2010/010906
Kind Code:
A1
Abstract:
Disclosed is a three-phase DC motor, which is constituted of eight poles, six slots and twelve segments and in which connection lines (25) are arranged all over the circumference of a rotation shaft. When individual teeth (9) are assigned in the order of a U-phase, a W-phase and a V-phase, the wind starting end (61) and the wind ending end (62) of a coil (12) of each phase wound on each teeth are connected in the order of the U-phase, the V-phase and the W-phase. The wind starting end and the wind ending end are connected with the segments which exist near the leading positions of those wind starting end and wind ending end. By the constitution thus made, the three-phase DC motor, in which the coil winding works can be easily performed while the magnetic pole number being made multiple, can be provided.
