Linear motion mechanism based on resonance magnetic coupling technology

Abstract

The invention relates to a linear motion mechanism based on a resonance magnetic coupling technology. The linear motion mechanism comprises a wireless energy transmission module and a linear motion mechanism body. The wireless energy transmission module comprises a direct-current power supply, a signal generator, an inverter circuit, a transmitting coil, a receiving coil and a rectifying circuit; and the linear motion mechanism comprises a base, a motor stator, a motor rotor, a guide rail, a sliding block and a motor controller. The signal generator provides a current signal for the circuit, and the inverter circuit converts direct current into alternating current; the transmitting coil converts a received circuit signal into an alternating magnetic field, and the receiving coil converts magnetic field energy into alternating-current electric energy; the rectifying circuit converts alternating current into direct current with the size and the frequency required by the linear motor through rectification, and is connected with the linear motor through the motor controller to supply power to linear motor equipment, so that the linear motor equipment does linear motion. The mechanism is small in size, stable and reliable in work and low in noise, the constraint of a tank chain on the motion of the linear motor is eliminated, and the motion precision of the linear motor is improved.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a linear motion mechanism based on resonance magnetic coupling technology. Background technique [0002] Since the linear motor was born, it has been widely used because of its excellent performance. However, due to the existence of the linear motor tank chain, it will not only generate a lot of noise, but also have a greater impact on the motion performance of the linear motor. Production and manufacturing have caused great inconvenience, so a new technology is urgently needed on the market to replace the traditional tank chain power supply method to solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a linear motion mechanism based on resonant magnetic coupling technology, which is small in size and easy to operate, in order to solve the problem that the linear motor tank chain in the pri...
