转动惯量 dynamic moment of inertia; inertia moment; moment of gyration; moment of inertai; rotary inertia; rotating inertia; rotation inertia; rotational inertia; rotor inertia
Satisfied with the technical request , the volume and weight of the rotor , moment of inertia of rotor , electromechanical time cost were reduced , and power density of brushless dc motor was improved by means of calculation 在满足技术要求的前提下,通过计算达到了减小电机的体积重量、减少转子转动惯量及机电时间常数、提高无刷直流电动机功率密度的目的。
Permanent magnet synchronous motors ( pmsm ) have high magnetic energy product . in the same volume , it can be smaller and lighter than asynchronous motor . in addition , it has stiff mechanical character and small rotor moment of inertia , so it is often used as servo motor under the condition of high torque response and high performance 永磁同步电动机具有较高的磁能积,相同容量下可以做到比异步电动机体积更小、重量更轻,而且由于机械特性硬、转子转动惯量小,很适合作为伺服电机,用于高转矩响应、高性能要求的场合。
