| 摘 要： | The heating calculation of three-phase squirrel-cage asynchronous motor on the condition of starting for a prescribed rotary angle is firstly studied with time dissection method and its corresponding algorithm is provided. Then based upon the algorithm, a new method for motor power selection is established. Motor initial power determined by load power is checked and modified in terms of time criterion, heating criterion, and starting torque criterion. An appropriate motor power which meets three criterions is obtained at last, in the meantime, working displacement matrix and frequency matrix used for control are acquired. Lifting motor of MDJ1800 low-level high-speed palletizer is taken as a real case hi the paper.
