Title:
METHOD FOR MANUFACTURING ELECTRIC MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/235417
Kind Code:
A1
Abstract:
An electric motor includes motor connection terminals (31a1, 31a2, 31a3). A control substrate (41b) has through-holes (41b1, 41b2, 41b3) corresponding to the motor connection terminals. Connection parts (50) that are made of a metal and that electrically connect the electric motor and the control substrate (41b) include: bonding parts (51) bonded to the motor connection terminals and linking parts (52) having respective one ends linked to the bonding parts (51) and the respective other ends bonded to the through-holes. Provided is a method for manufacturing an electric motor control device, the method comprising: a first bonding step for bonding the motor connection terminals and the bonding parts (51); and a second bonding step for bonding the through-holes and the linking parts (52) in the state where, with heat transmitted from the bonding parts (51) heated in the first bonding step, the linking parts (52) have a higher temperature than the temperature of external space.
