Abstract:
An actuator for a compressor element, the actuator comprising an electrical motor with a motor casing which defines a motor chamber in which a motor rotor is positioned rotatably with the help of one or more motor bearings in relation to a motor stator, whereby the motor stator is built of laminations around which windings are attached and whereby the motor rotor is built of a shaft with laminations, whereby the actuator is further equipped with a cooling circuit for a coolant, wherein the coolant is water, the motor bearings are water-lubricated, the shaft on the motor rotor is made from stainless steel, the windings are embedded in an epoxy resin and a composite sleeve is applied around each of the laminations on the motor rotor and on the motor stator.
