ELECTRIC DRIVE FOR OPERATING WINDOW, SLIDE OPEN-CLOSE TYPE ROOF, ETC.

摘要

PURPOSE: To achieve miniaturization and lower cost while guaranteeing quick disconnection of an electric motor when windows have reached a terminal position by using radio interference suppression coils as inductors, which are arranged on a brush holding part. CONSTITUTION: A radio interference suppression unit is enclosed by a brush holding part and comprises radio interference suppression choke coils 4, 5 connected in series with carbon brushes 31, 32 and a radio interference suppression capacitor 6. An operating switch 10 connected in series with the radio interference suppression choke coil 4 shuts off currents to the carbon brushes 31, 32 when sliding windows driven by a dc commutator motor have reached a terminal position.
