Title:
MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/097320
Kind Code:
A1
Abstract:
A fuse module (22) for fail safe has a fuse circuit element (32) mounted on a fuse circuit board (31) and is connected to wire terminal portions (36) comprising the wire ends of stator coils. The fuse circuit board (31) has through-holes (33a) and land portions (33b) as main terminals (33), and the wire terminal portions (36) are inserted into the through-holes (33a) and then soldered or welded. The fuse circuit board (31) is supported in a cantilever manner by a table-like portion (52), and a space (53) is ensured between the fuse circuit board (31) and the surface (51) of a housing (7) around the main terminals (33). Loss of heat is prevented by the space (53) during soldering or welding, thereby enabling the soldering or the welding.
