Filed: 2002-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for driving an electromagnetic actuator which can be speedily operated with the voltage of a DC voltage source or higher without requiring a step-up circuit and a bypass circuit.  <P>SOLUTION: A power source voltage Vcc is connected to the neutral point 3 of driving coils L1, L2 of an electromagnetic actuator driving device 1. When the low potential side output transistors Q3, Q4 are turned off by PWM control, the driving coil L2 through which a sync current is made to flow generates counter electro-motive force of the power source voltage or higher. Thus, a regenerative current is made to flow via the ON-state high potential side output transistors Q1, Q2, this regenerative current serves as the source current for the other driving coil L1 and the charge current of a capacitor Co. When the low potential side output transistors are turned on again with the next oscillation pulse from an oscillator 16 for PWM, the source current of the driving current L1 is supplied with the discharge current from the capacitor Co. By repeating this operation, the driving coils L1, L2 of the magnetic actuator are directly PWM-controlled by pseudo full-wave energizing.  <P>COPYRIGHT: (C)2003,JPO

Then, the motor is driven and controlled so that torque corresponding to the corrected torque command can be outputted from the motor. Narrowing the allowable range of the motor output change rate dP/dt as the revolution acceleration AX of the motor becomes larger is based on the tendency of the output from the motor becoming excessively large, under the condition of the revolution acceleration AX in creases when the driving wheels slip.  <P>COPYRIGHT: (C)2003,JPO
