Title:
AC-INPUT TYPE BRUSHLESS DC MOTOR AND ELECTRIC APPLIANCE MOUNTING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/001759
Kind Code:
A1
Abstract:
A current control circuit controls the average current of an inverter circuit.
A current indication circuit increases or decreases an average current value
supplied to the inverter circuit with respect to a reference current so that a
correlation indicated by a correlation indication circuit is obtained. This
enables the shape of the speed-torque characteristics of a brushless DC motor
to be set so that the torque increases as the speed increases.The speed-torque
characteristics indicating that the torque increases as the speed increases
are suitable for a fan drive.
