Title:
DIRECT CURRENT MOTOR AND POWER SUPPLY METHOD FOR THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/036717
Kind Code:
A1
Abstract:
A direct current motor whose rotor can be downsized and power supply method for the motor. A direct current motor (11) includes a stator (12) and a rotor (13). The stator (12) has a core (21), a coil (22) wound on the core (21), and a commutator (23) connected to the coil (22). The rotor (13) is rotatably placed on the inner periphery side of the stator (12) and includes a yoke (37) and a magnet (38) fixed to the yoke (37). Slip rings (31, 32) and brushes (44, 48) supply power that is supplied to the stator (12) to the rotor (13). Brushes (43, 47) arranged on the rotor (13) are connected to the slip rings (31, 32) and slide on the commutator (23).
