摘要:
A cooling system for a brushed electrical machine includes a cooler configured to cool down a rotor and a commutator of the machine. There is a controller configured to adjust the cooling effect of the cooler in response to monitored rotor and commutator temperatures. The cooler includes a fan and an auxiliary motor configured to rotate the fan.
