Title:
電動機の駆動制御方法
Document Type and Number:
Japanese Patent JP5624810
Kind Code:
B2
Abstract:
The method for drive-controlling electric machinery, in which a multiphase motor (1) is used as a driving source of an assist mechanism, is performed by a control unit (6) including a drive circuit (9, 10) for driving the multiphase motor (1). The method is characterized in that the control unit (6) controls to stop a rotor (2) at a load-holding stop position, at which rotation of the rotor (2) is stopped in a state where motor a coil (3) is energized and the rotor (2) is in a load-holding state, and that the load-holding stop position is angularly shifted an electric angle of 180/n (n is number of phases and an integer two or more) degrees, in a prescribed rotational direction, with respect to a previous load-holding stop position of the rotor (2).
