Abstract: This paper introduced the feature of PSoC and proposed a scheme for a new ultrasonic motor driver. The hardware circuit structure and the software designing of relevant functions for the driver were described in detail. A micro-driver using PSoC chip CY8C29466 as the main controller was designed. The micro-drive was applied to the ultrasonic motor, of which the stator’s diameter is 60 mm. Experimental results show that this scheme is valid and feasible. Compared with present drivers, its stability was greatly improved. What’s more, it had compact circuit and fewer components.
