Designing a new hybrid piezo-magnetic linear motor

In this paper, a new hybrid piezoelectric/magnetic linearmotor is presented. Piezo-magnetic motor consists of slider,stator, and rotor. This piezo-magnetic motor is based oninchworm motion principle. The piezoelectric linkagemoves slider forward or backward and the magnetic linkageis the connection between piezoelectric and slider. Becauseof the power of the magnetic linkage and by using properlythe piezoelectric device with micro movement, this linearmotor has precision and potency simultaneously. Thepresented motor is simulated in finite element software andits operation is investigated. The piezo-magnetic linearmotor worked with about 60-volt pp and by changing thefrequency of voltage that induced to piezoelectric linkages,the velocity of linear motor is controlled.
