Abstract
This disclosure relates to a small-sized, high-power micromotor with built-in cooling medium pipes for medical treatment. The motor which is structurally of the type wherein the stator of the motor includes a permanent magnet and a magnetic yoke encircling the magnet is improved in that the cooling medium pipes are incorporated into the motor by providing at least one cooling medium pipe receptor portion in the magnetic poles of the yoke or in the vicinity of the yoke without reducing motor performance nor increasing the diameter of the motor.
