Novel oscillating motor based on linear-rotary double degree of freedoms and control method

Abstract

The invention discloses a novel oscillating motor based on linear-rotary double degree of freedoms and a control method. The motor comprises a prime mover and a driven machine. The prime mover body is fixed to a prime mover base. A prime mover mover is connected with the prime mover body. A prime mover mover permanent magnet is disposed on the outer surface of the prime mover mover. A driven machine fixed cast body is fixed to a driven machine base. A cylinder is fixed to the driven machine fixed cast body, and is connected with a driven machine mover. A driven machine mover permanent magnet is disposed on the inner surface of the driven machine mover. The prime mover mover is coaxially nested inside the driven machine mover. A gap is arranged between the prime mover mover permanent magnet and the driven machine mover permanent magnet. The prime mover drives the driven machine mover through the prime mover mover such that the driven machine linearly reciprocates and compresses the air through the cylinder. The novel oscillating motor solves the low efficiency, the large noise, the low power, the transmission mechanism wear proneness, and the low energy density of a conventional motor, thereby improving the efficiency and stability of an oscillating motor system.

Description

Technical field [0001] The invention relates to air-conditioning compressor equipment, in particular to a novel oscillation motor based on linear-rotation dual degrees of freedom and a control method for high power, low power consumption, low noise, and high oscillation frequency. Background technique [0002] For many years, although CNC machine tools have been reformed many times in the industry, the structure that uses a rotating motor to drive a crank connecting rod has been the most widely used. The traditional control method of the crank connecting rod structure driven by the rotating electric machine has a simple control strategy, but the hardware structure is complicated. At the same time, due to its inherent structural characteristics, the noise during the oscillation process is large, the energy conversion efficiency is low, and the structure is easily damaged. In recent years, with the continuous development of technology and the continuous improvement of process qual...
