| description | To provide a motor actuator for an on-vehicle apparatus, capable of shutting-down a power supply to a motor while suppressing failure of a circuit element by a counter electromotive force.SOLUTION: A motor actuator of the present invention has a first solid state relay 41 and a second solid state relay 42, which have an inverse parasitic diode between a battery 70 and an inverter 30. When shutting-down a power supply from the battery 70 to the inverter 30, the first solid state relay 41 is set to an off state, or field effect transistors 31 to 36 of the inverter 30 are set to an off state, and thereafter, the second solid state relay 42 is set to the off state.SELECTED DRAWING: Figure 1
【課題】逆起電力による回路素子の故障を抑制しつつモータへの電源供給を遮断できる、車両搭載機器用モータアクチュエータを提供する。【解決手段】本発明のモータアクチュエータは、バッテリ７０とインバータ３０の間に、寄生ダイオードの向きが逆である第１のソリッドステートリレー４１及び第２のソリッドステートリレー４２を有し、バッテリ７０からインバータ３０への電力の供給を遮断するとき、第１のソリッドステートリレー４１をオフ状態とするかまたはインバータ３０の電界効果トランジスタ３１−３６をオフ状態とし、その後、第２のソリッドステートリレー４２をオフ状態とする。【選択図】図１ |
