Title:
回転電機、及び回転電機を備えるシステム
Document Type and Number:
Japanese Patent JP7259926
Kind Code:
B2
Abstract:
A stator (50) in a rotating electrical machine (803a) has a slot-less configuration. The rotating electrical machine comprises a control device (110). The control device sets the q axis command current on the basis of: map information associated to a torque command value for the rotating electrical machine and having the q axis command current prescribed therein; and the torque command value. The control device corrects the q axis command current so as to reduce the impact that change in the temperature of a magnet unit (42) has on the relationship between the torque command value and the q axis command current. The control device operates an inverter (101) for controlling the q axis current flowing through a stator winding to the corrected q axis command current.
