Title:
MOTOR CONTROLLER
Document Type and Number:
Japanese Patent JP2004282803
Kind Code:
A
Abstract:
To suppress abrupt change of a motor torque in a system for switching an amplitude fixed voltage vector phase control and an dq-axis current feedback control in response to a high-speed driving region and a low-speed driving region.
A motor controller presets the set value of a second voltage vector operating means 12 to the set value of a first voltage vector operating means 11 so as to continue a voltage vector at a switching time from a driving mode using the output result from the first voltage vector operating means 11 to a driving mode using the output result from the second voltage vector operating means 12.
