摘要： In apparatus and method for controlling a rotation speed of a brushless motor, the rotation speed of the rotor is lowered by a predetermined gradient for the rotation speed of the rotor to be reached to a present target value of the rotation speed of the rotor when the rotor of the motor is rotating at a previous target value of the rotor of the motor previously calculated and the present target value of the rotor of the motor is lower than the previous target value thereof at which the rotor of the motor is rotating. The predetermined gradient is, for example, 100% per unit time.

摘要： A control device for a brushless motor comprises a first section which stores a data table provided to minimize a difference between an actual rotation speed of the motor and a target rotation speed of the same. The difference is inevitably produced when the motor is rotated. The data table provides a plurality of rotation speed ranges each having data for a rotation speed of the motor. The control device further comprises a second section which compares the target rotation speed and the data table to select data which corresponds to the rotation speed range to which the target rotation speed belongs. The control device further comprises a third section which corrects the target rotation speed based on the selected data and drives the brushless motor in accordance with the corrected target rotation speed.
