Document Type and Number:
Japanese Patent JP7358726
Kind Code:
B2
Abstract:
Provided is a motor device capable of detecting entry of water into a housing before a control circuit is submerged. A first motor bus bar (60) includes a first U-phase motor bus bar (60u), a first V-phase motor bus bar (60v), and a first W-phase motor bus bar (60w). A first control circuit (32) is connected to the first motor bus bar (60). The first U-phase motor bus bar (60u), the first V-phase motor bus bar (60v), and the first W-phase motor bus bar (60w) are disposed on the lower side with respect to the first control circuit (32) in a gravity direction. The first control circuit (32) detects entry of water into a motor housing of the motor device, based on the status of power supply to the first U-phase motor bus bar (60u), the first V-phase motor bus bar (60v), and the first W-phase motor bus bar (60w).
