【Abstract】 A novel ultrasonic motor driver with automatic frequency tracking is described in this paper,and its phy sical work condition is interpreted by theoretical formulae and LC curve diagram.Experiments demonstrate that the driver can track the resonance frequency variation of the motor and keep the motor to work well.更多还原
