1. A compressor system comprising:
a compressor configured to compress a fluid in piping configured to convey the fluid between locations; and
an electric motor configured to turn the compressor to cause the compressor to compress the fluid, the electric motor controllable by a motor drive and configured to shunt heat generated by harmonics to the fluid without use of one or more filters in the motor drive, and without use of one or more filters in an electrical connection between the motor drive and the electric motor;
wherein the electric motor comprises a cage configured to shunt the heat generated by the harmonics.
