一种新型的三相感应电动机十多年前在我国首次设计和制造出来了,命名为延边三角形鼠笼式感应电动机。本文基于普通鼠笼式感应电动机的基本方程组和等值电路,导出了这种新型电动机的基本方程组和等值电路,并且根据它的等值电路,导出了起动电流和起动转矩公式。藉等值电路建立了新型的和普通型的电动机之间的关系。从等值电路的观点看,普通鼠笼型电动机是新型电动机的一种特殊情况。利用起动电流和起动转矩公式,在科学研究中我们可以获得满意的结果。
A new type of three-phase induction motor was first designed and manufactured in our country more than a decade ago and named Yanbian triangular squirrel-cage induction motor. Based on the basic equations and equivalent circuit of ordinary squirrel-cage induction motor, the basic equations and equivalent circuit of this new motor are derived. Based on its equivalent circuit, the starting current and starting torque formula are deduced. Equivalent circuit by the establishment of a new and ordinary type of relationship between the motor. From the standpoint of the equivalent circuit, a common squirrel-cage motor is a special case of a new motor. Using the starting current and starting torque formula, we can get satisfactory results in scientific research.
