【摘要】 以小型往复式制冷压缩机为典型研究对象,通过对其封闭壳体的振动分析,指出了壳体振动的基频即为电机的转速。提出了一种基于微机的通过测量振动基频来间接测量封闭体内电机转速的方法和构成。更多还原

【Abstract】 Taking the small hermetic refrigerating compressor as typical subject investigated, analyzing the vibration of its shell, indicating that the basic vibration frequency is equal to the motor rotation, and the method and construction based on computer to measure indirectly the speed of hermetic motor via measuring the basic vibration frequency were introduced in this paper.更多还原
