摘要： A driving system capable of producing large driving force to drive a load and positioning it rapidly with high accuracy by use of a controller capable of driving a motor at a high speed with high torque and high efficiency. When target position data from a computer (35) is stored in a counting circuit (30) of an operation mode switching circuit (330), a load member is driven at a high speed by a large driving force through a ball screw-nut mechanism by a motor operating as a two-phase reluctance motor at a high speed with high torque and high efficiency. When the count value of the counting circuit which is decremented with the movement of the load member reaches a first set value, the sequence of application of the position detection signals indicating the motor rotating position to a power control circuit is changed by the signal switching circuit (320), and the motor is thus decelerated until the motor speed reaches a predetermined speed. The motor is then operated at a constant speed. When the count value drops to a second set value, the motor is driven as a stepping motor in accordance with a signal from a stepping signal generation circuit (27, 28a-28c). When the count value becomes zero, the motor stops and positions accurately the load member to a target position.
