A linear-rotational dual-degree-of-freedom oscillating motor and its 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 linear-rotation dual-degree-of-freedom oscillating motor and a control method for high power, low power consumption, low noise, and high oscillating frequency. Background technique [0002] For many years, although many reforms have been made to the CNC machine tool in the industry, the most widely used structure is the structure of the crank connecting rod driven by a rotating motor. The traditional control method in which the rotating motor drives the crank connecting rod structure has a simple control strategy, but the hardware structure is complex. 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 science and technology and the continuous improvement of process quality, tr...
