Title:
SPLIT CORE STATOR AND CONCENTRATED WINDING MOTOR
Document Type and Number:
WIPO Patent Application WO/2005/109605
Kind Code:
A1
Abstract:
A split core stator (4) of a concentrated winding motor (1) has, on the opposite sides in the direction of the center axis of a stator core (10) constituted by coupling a plurality of split cores (9) annularly, a first printed board (11) on which connection patterns (18-23) for connecting coil windings (13) wound around the respective split cores (9) in a specified form are formed and a second printed board (12) on which connection patterns (25-28) are formed. Since the connection patterns and bonding lands formed on the connection patterns are distributedly arranged on both printed boards (11, 12), a large number of connection patterns and bonding lands can be arranged and the area thereof can be secured. A split core concentrated winding motor having a large number of small-diameter coil windings can thereby be manufactured.
