Abstract

Disclosed is a micromotor with a motor housing (20) formed of polymer material. Said motor housing (20) surrounds the stator (24). The motor drives a pump part (12), which pushes fluid along the motor housing (20). The polymer material of the motor housing (20) contains an electrically isolating filler having caloric conductibility, especially Al2O3. Thereby, the temperatures arising in the motor housing are reduced. Furthermore, the hollow spaces of the coils (24a) of the stator can be filled up with a polymer material which contains a filler with caloric conductibility. The internal temperature of the motor is reduced as a result of the heat carried away to the fluid flowing around the motor. The micromotor is particularly useful for an intravascular blood pump.
