三元平衡法是一种通过作图找出不平衡点位置和质量的简单实用的动平衡试验方法。它适用于电机铸铝转子原始不平衡量较大、动平衡机又不能校正或者工厂缺少动平衡机的情况,同时也适用于不能在平衡机上搞动平衡的特殊类型电机和其它旋转机械。下面以电机铸铝转子为例介绍三元平衡方法。三元平衡法所谓三元就是在电机铸铝转子表面均匀取三点,每点相差120°,用粉笔作好标志,如1,2,3三点。根据电机振动测试 Ternary balance method is a simple and practical dynamic balance test method to find out the location and quality of unbalance points by plotting. It applies to the motor cast aluminum rotor larger amount of unbalance, dynamic balancing machine can not be corrected or the factory lack of dynamic balancing machine, but also applies to balancing machines in the balance of the special type of motor and other rotating machinery. Below the motor cast aluminum rotor as an example to introduce ternary balance method. Ternary balance method The so-called ternary is in the motor cast aluminum rotor surface evenly take three points, each point difference of 120 °, make a good sign with chalk, such as 1,2,3 three. According to the motor vibration test
