Title:
電動機のための直列抵抗アッセンブリおよび電動機を駆動するための直列抵抗アッセンブリを有する回路配置
Document Type and Number:
Japanese Patent JP4495150
Kind Code:
B2
Abstract:
The invention relates to a series resistor assembly (1) for an electric motor (M), in particular for an electrically driven ventilating fan in a vehicle. Said assembly comprises a series resistor (2) for controlling the RPM of the electric motor (M) in one or more RPM stages (ST1, ST2, to STn) and a thermal link (6) that is optionally connected in series to the series resistor, a reversible switching element (4) for at least one of the RPM stages (ST1, ST2) being integrated into said assembly. The invention also relates to a circuit arrangement (14) comprising a reversible blocking protection and fire protection element for the electric motor (M) and/or the series resistor assembly (1), diverse status signalling lines (24a to 24c) being used to evaluate and control the ventilating fan system.
