Title:
DC MOTOR
Document Type and Number:
WIPO Patent Application WO/2001/037406
Kind Code:
A1
Abstract:
A DC motor comprises a stator (2) including n phase coils arranged at substantially regular intervals around the stator core (3), a rotor (8) including a plurality of permanent magnets (9) at respective positions corresponding to the coils (4) of the stator (2), and an energizing device including commutators (11) that energizes the coil of the stator by producing n phases from the direct current supplied from the power supply through the rotor (8). Noise limiters (23) are provided on brush holders (21) corresponding to the coils in the energizing device.
