Title:
MOTOR CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2012/111504
Kind Code:
A1
Abstract:
A phase voltage setting means defines an actual current phase range that includes a current phase error range obtained on the basis of parameters containing instrumental errors of the motor and/or an inverter; defines a stable operating current phase range in which a rotor position can be detected through sensorless control; and sets a target current that is obtained by adding a predetermined phase difference, which corresponds to a revolution speed detected by a revolution speed detection means, to a current that is set by means of current vector control, such that the actual current phase range falls within a stable operating current phase range.
