一、机电设备配套中的潜能由于种种原因、在生产实践中形成“大电机轻负载”(即大马拉小车)的问题相当严重;致使异步电动机的效率和出力偏低,功率因数恶化,线损增加,浪费能源,不仅增大投资还使设备不能物尽其用。一般电机是由机械设备生产厂随主机成套供应,根据机械设备所需轴功率乘以富裕系数找出相应规格电机;又因电机级差较大,乘以富裕系数后的数据,不正巧是对应电机规格,为了保险一点,向上靠 First, the potential of mechanical and electrical equipment supporting For various reasons, the formation of the production practice “large motor light load ” (ie, the horse car) problem is very serious; resulting in asynchronous motor efficiency and output is low, the power factor worsened , Line loss increased, a waste of energy, not only increased investment but also make the equipment can not make the best use of. General motor is supplied by the mechanical equipment manufacturer with the host complete sets of supply, according to the required shaft power multiplied by the richness of machinery and equipment to find the appropriate specifications of the motor; and because of the larger motor level, multiplied by the coefficient of wealth after the data is not coincident with the motor Specifications, in order to insure, up by
