盘式异步无级调速电机机械特性分析

Analyses of Mechanical characteristic of Disc Type Asynchronous Steplessly Adjustable Speed Motor

推导了盘式异步无级调速电机的机械特性及临界转矩、临界转差率的理论计算公式,起动转矩等于临界转矩时有关参数间的关系等。并给出不同励磁电流下机械特性的试验曲线族,验证了推导的理论公式。

The calculating formulas of mechanical characteristic,critical torque and critical slip and the relation between relevant parameters when starting torque is equal to critical torque of disc type asynchronous steplessly adjustable speed motor are deriven in the paper and the family of mechanical characteristic test curves in the different exciting current are also given, those are in good agreement with the theoretical analyses.
