Can device.The passive sensing system of energy regenerating additionally, being on the increase to transducing signal demand, can be carried out with Mechatronic Systems
System also becomes study hotspot.
Additionally, there being substantial amounts of rotary part in various electronic products in prior art, such as the light in micro electronmechanical product turns
Wheel of live spindle in axle, Digit Control Machine Tool and carrier vehicle etc., in order to reach finer working condition, is required to
Its rotating speed is measured, and is transferred in whole machine controller carry out respective handling；Needing to carry out rotating speed to corresponding rotating shaft
During control, also usually use brake and it is braked.In the prior art, sensor and brake are usually discrete
Exist.With the constantly in short supply of the energy and other performance requirements in addition it is also necessary to countershaft rotating mechanical energy is reclaimed, to increase
Plus the efficiency of energy utilization of whole machine, the such as regeneration brake system in new-energy automobile field, will wheel in vehicle braking procedure
Rotation function be transferred to electromotor, be recycled into electric energy and be used.However, the energy in existing brake energy recovering system
Retracting device is also all independently of brake, not only increases system complexity so that whole machine is difficult arrangement, reliability fall
Low, or obtaining main screw lift increases, and is unfavorable for the raising of capacity usage ratio.
Piezoelectric actuator realizes electric energy to the conversion of mechanical energy using the inverse piezoelectric effect of piezoelectric ceramics, can be in body
