Title:
MOTOR CONTROL DEVICE, MOTOR DRIVE DEVICE, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/186471
Kind Code:
A1
Abstract:
The purpose of the present invention is to effectively drive a motor. When a sun gear shaft (34) connected to a drive shaft (12) on the electric vehicle side is fixed, a rotor (22a) of a motor (20a) connected to a ring shaft (30) and a rotor (22b) of a motor (20b) connected to a carrier shaft (32) are connected to each other. In this state, the motors (20a, 20b) are driven to rotate opposite to each other, and a correction value of the position of the rotor (22b) detected by a rotational position detection sensor (25b) is calculated so that the output torque (Ta) of the motor (20a) and the output torque (Tb) of the motor (20b) are balanced with each other and the acceleration of each of the rotors (22a, 22b) becomes zero.
