Title:
MOTOR DRIVING DEVICE AND CAR PROVIDED WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/069779
Kind Code:
A1
Abstract:
A controller (40) converts a torque command value of an alternating current motor (M1)
into an electric current command value and uses electric current control in which
PI feed-back control is carried out to make a real electric current value consistent
with the electric current command value. Further, the controller (40) sets a
target flowing amount of cooling water flowing through a refrigerant path (50-56)
in response to the converted electric current command value, generates a signal
to drive a water pump (66) in order for the set target flowing amount of the cooling
water to circulate, and outputs the same to the water pump (66). A rotating speed
of the water pump (66) is controlled in response to a signal (PWR) of the controller (40)
in order for the target flowing amount of the cooling water to circulate through the
refrigerant path (50-56).
