  • This abstract for appeared for patent application number 17795096 Titled 'MOTOR CONTROL DEVICE AND ELECTRIC POWER STEERING DEVICE'

Simplified Explanation

The abstract describes a motor control device that aims to reduce the unpleasant sensation caused by vibration or noise in a motor. The device consists of two control units, one for each motor winding. The first control unit determines the lower value between its own power supply voltage and the power supply voltage of the second control unit. It then outputs this selected power supply voltage. The device also calculates target values for d-axis current, q-axis voltage, and d-axis voltage using the selected power supply voltage.


Original Abstract Submitted

A motor control device that enables a reduction of an unpleasant sensation caused by vibration or noise occurring in a motor is obtained. A motor control device including a first control unit that drives a first motor winding and a second control unit that drives a second motor winding is such that the first control unit selects the lower of values of an own power supply voltage and a power supply voltage of the second control unit and outputs a post-selection power supply voltage, and computes a target d-axis current, a target q-axis voltage, and a target d-axis voltage using the post-selection power supply voltage.
