Title: Apparatus and method for driving stepping motor
Inventor: IRIBE MASATSUGU
IPC: G11B17/22
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a stepping motor driving apparatus and its method which makes it possible to increase its maximum rotating speed, without changing the parameters of a stepping motor i.e., without performing a design change of the motor. SOLUTION: In the stepping motor driver 30, accelerating-time torque is gained by increasing driving currents, namely current flowing in the motor, to be supplied to the coils of the stepping motor 11 from an A-phase driver 32 and a B-phase driver 33, and making its pull-in torque larger, when the stepping motor 11 is started. When the motor 11 is accelerated to some extent, the motor current is made smaller, its pull-out torque is made larger, and high- speed rotating-time torque is gained. When the motor is stopped, the motor current is made larger, the pull-in torque is made larger, and decelerating-time torque is gained.
