Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/058640
Kind Code:
A1
Abstract:
A motor control device (100) controls energization to a motor (80) having two three-phase winding sets (801, 802) configured so that mutual electrical angle phase difference becomes ± (φo + 120 × n)° (0 <φo ≤ 60°, n is an integer). The current redistribution unit (35) of a current command value calculation unit (30) performs "current redistribution processing" when a predetermined condition is satisfied. In the current redistribution processing, the current redistribution unit (35) calculates, for each electrical angle (θ), a specific maximum current value that is the maximum value among the absolute values of three-phase current command values of respective systems. The current redistribution unit (35) redistributes the current command values of the two systems so that the ratio between the specific maximum current value I1_max (θ) × (1 + α(θ)) of the first system after the redistribution and the specific maximum current value I2_max (θ) × (1 - α(θ)) of the second system after the redistribution approaches a predetermined target ratio.
