Problems solved by technology
[0003] The existing technology has the following disadvantages: using a single resignation telescopic driver to drive the stator to rotate, its output torque is small; driving the rotor to rotate through the surface contact friction between the stator and the rotor will cause energy loss and heat generation, and the efficiency is relatively low, and the output The magnitude of the torque is also limited by the roughness of the contact surface of the material

The invention discloses a giant magnetostrictive stepping motor. The giant magnetostrictive stepping motor comprises an output shaft, a rotation driving device composed of rotors, a giant magnetostrictive actuator, connecting rods, a stator and a clutch, a bearing, a shell and an end cover. The rotation driving device composed of the rotors, the giant magnetostrictive actuator, the connecting rods, the stator and the clutch is adopted for the motor, the giant magnetostrictive actuator is used for driving the connecting rods to drive the rotors to rotate, and meanwhile rotation of the rotors is output through sequential cyclic actions of the clutch. Compared with a traditional giant magnetostrictive drviving motor, the giant magnetostrictive stepping motor has the advantages of being compact in structure, large in power to weight ratio, large in output torque, high in efficiency, stable in operation and capable of achieving rotation by any angles in the forward direction and the backward direction, and wider application of the giant magnetostrictive stepping motor in the field of precision mechanical drives is promoted.
Description
technical field [0001] The invention relates to a stepping motor in the field of precision mechanical drive, in particular to a giant magnetostrictive stepping motor. Background technique [0002] Giant magnetostrictive material is a special functional material whose size can expand and contract with the change of external magnetic field, and whose magnetostriction coefficient is much larger than that of traditional magnetostrictive materials. Giant magnetostrictive materials have the characteristics of high electromechanical conversion efficiency, high energy density, fast response speed, large output displacement, high reliability and easy driving. Transducers, speakers, linear drives, and rotary drives made of giant magnetostrictive materials have been widely used in the fields of national defense and military, home appliances, robots, and micro-mechanical electronic systems. The existing giant magnetostrictive motor literature Chinese patent "a single-drive two-way rota...
