Torque for an Inertial Piezoelectric Rotary Motor [PDF]

open access: yesThe Scientific World Journal, 2013
For a novel inertial piezoelectric rotary motor, the equation of the strain energy in the piezoceramic bimorph and the equations of the strain energy and the kinetic energy in the rotor are given. Based on them, the dynamic equation of the motor is obtained. Using these equations, the inertial driving torque of the motor is investigated.
