Driving apparatus of vibration type actuator |
摘要 |
A driving apparatus of a vibration type actuator includes an apparatus for forming a vibration wave by applying four-phase AC signals having temporal phase differences to four-phase driving phases arranged at intervals of ¼ wavelength, which includes first and second transformers and two-phase driving phases connected to the secondary terminals of the respective transformers, thereby simplifying the arrangement of a driving circuit.
