Title:
MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/097319
Kind Code:
A1
Abstract:
Ａ stator (1B) has first system stator coils (U1, V1, W1) and second system stator coils (U2, V2, W2), each of which receives power supply from an inverter module (21). A fuse module (22) has two fuse circuit elements (32) which correspond to the respective systems. In each of the fuse circuit elements (32), phase lines of U, V, and W are connected to a neutral point (40), and a fuse (38) lies between the neutral point (40) and the coils. The fuse (38) is blown by power supply from a control terminal (34) to a heater (39) which is housed in the fuse circuit element (32).
