Abstract:
1. A control device for a motor, comprising: a memory for storing an excitation pattern of the motor; a first pattern control circuit for reading an excitation pattern from said memory and supplying the excitation pattern to a motor driver for driving the motor; a second pattern control circuit for reading an excitation pattern from said memory and supplying the excitation pattern to the motor driver or another motor driver; and an output control circuit capable of selecting a first output mode for using said first pattern control circuit and said second pattern control circuit independently and for supplying the excitation pattern to first and second motor drivers from said first and second pattern control circuits respectively, or a second output mode for using said first pattern control circuit and said second pattern control circuit synchronously and for supplying the excitation pattern to a single motor driver from said first and second pattern control circuit.
