Abstract

Currently there is no information about the optimal value of the rate of change pulse duty factor coefficient in speedingup modes of asynchronous motor (AM) with the modified pulse control system, where the impact components of the thermal effect intensity is the lowest one.
The aim is to estimate the derivation of the stator temperature, the temperature of AM with the modified system in conditions of frequent starts, depending on the intensity of its speed up.
To estimate the derivation of the stator temperature, the temperature of AM with the modified system, depending intensity of its speed up the complex simulation model of electromagnetic and thermal process are designed. This model describes the thermal transient process in structural elements of AM and allows considering peculiarities of electromagnetic energy transformation in thermal energy, heat transferring and heat interchanging processes. The use of AM with the modified system pulse control will reduce the derivation of the stator temperature, the temperature of AM up to 12 times compared to derivation of the stator temperature, the temperature of AM at direct start. The optimal thermal conditions of AM at rate of change pulse duty factor coefficient equal to 0,16 pu/s is provided.
The results of research can be used to optimize the design of pulse control systems, thermal protection of AM with the modified system for heavy-duty, where the frequency of starts reaches 3000 cycles per hour
