Title:
MOTOR DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/128102
Kind Code:
A1
Abstract:
The invention is related to a means for controlling the driving of a motor (6) including a motor used in, for example, an electric vehicle and using a battery as a power supply, and is applied to a motor driving device (20) equipped with a connection mode switching circuit such as, for example, an inverter (31) capable of switching between a drive connection mode for driving the motor (6) by battery power and a regeneration connection mode. The inverter (31) is configured so as to be able to be switched to a short-circuit connection mode for short-circuiting motor coils and generating brake force, and is further provided with a short-circuit current control means (26) for controlling short-circuit current flowing in the short-circuit connection mode and a regeneration- brake/short-circuit-brake switching control means (25) for switching the inverter (31) between the regeneration connection mode and the short-circuit connection mode.
