Abstract

In some industrial AC motor applications, higher heat dissipation results in faster rotor losses than that can be accommodated with conventional shaft-mounted-fan cooling designs. In this paper, one of the heat pipe technologies - rotating heat pipe - is presented as a means of enhancing motor rotor cooling. Novel rotating heat pipes are designed to improve heat transfer performance at various rotational speeds. Preliminary experimental results indicate that this thermal solution can effectively improve motor rotor cooling. Further, the rotating heat pipes with internal wicks can reduce temperature gradients at low rotational speed.
