Patent Searching and Data


Title:
MOTOR DRIVE APPARATUS AND COOLING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/196472
Kind Code:
A1
Abstract:
The present invention is provided with: a power conversion apparatus (10); and a control apparatus (40) that controls the voltage supplied to a motor by the power conversion apparatus. The d-axis inductance in the motor (30) is defined as Ld, the flux linkage of the motor (30) as φ, and the maximum output of the motor (30) in a device in which the motor (30) is mounted as Pmax. For an effective value voltage Vx=200 V, the motor (30) is configured such that the value of φ×Vx/Ld is larger than Pmax. The control apparatus (40) comprises a control mode that applies an effect value voltage higher than the effective value voltage Vx to the motor (30).
