变频器选型综述

本文从负载的转动惯量引起的加减速转矩、负载的阻力转矩出发,提供了换算到电动机轴的有效转矩和最大转矩的计算方法,以此作为选择电动机和变频器的基本依据,并指出变频器选型中应做的再次确认的要点。同时文中还提出了制动电阻选择方法和避免方法。

Overview of Inverter Selection

From the moment of inertia of the load caused by acceleration and deceleration torque, starting torque load resistance, provides the effectiveness of conversion to a motor shaft torque and maximum torque is calculated, select the motor and inverter as a fundamental basis, and that selection should be done inverter reaffirmed points. This paper also proposed selection method and avoid braking resistor method.
