【摘要】 本文提出了一种新装置,用于测量电机转子的转动惯量。它是应用气垫技术研制的一种新型仪器。由于采用了气流定轴及气垫转盘与气垫滑轮相结合的独特设计,摩擦可忽略,因而能得到较精确的结果。用此装置对直流伺服电机转子的转动惯量进行了测试。试验证明,精度较高。更多还原

【Abstract】 A new set-up for measuring the rotational inertia of electric machine rotor is presented in this paper.Air rotating disk is a new rotating instrument usingair cushion technique.Owing to the unique design that the axis of the rotatingdisk is fixed by the air flow and disk itself and the air pulleys are alsosupported by air cushion,the friction between all the moving parts of theinstrument can be ignored.Therefore,higher accuracy of experiments can beobtained.We have already measured on rotor of DC servo motor.Exprimentproves the new set-up possesses higher measuring precision.更多还原
