Abstract

The increasing demand for high speed, direct drive systems is driving a significant research effort on high speed electrical machines. Thermal management becomes a significant aspect to deal with as power loss per cooling surface area reduces as speed increases. Solid rotor induction machines are often considered at the high end of the speed spectrum as they offer a mechanically robust rotor structure. The current density distribution within their rotor structure typically results in high rotor losses and a significant portion of the total machine losses. In such machines the current distribution in the rotor itself is highly dependent on the rotor resistance and hence on the rotor temperature distribution. This paper will detail an effective model coupling both the electromagnetic and thermal domains to simulate operation of solid rotor induction machines.
