Canned motor

A canned motor 1 comprises a motor housing 2, a stator 5 fixed on the housing, and a rotor 9 rotatably mounted on the housing about an axis of rotation 10. A can 11 is fixed on the stator, radially between the stator and the rotor. At least one annular seal carrier 12 is fixed on the motor housing r...

Zusammenfassung:A canned motor 1 comprises a motor housing 2, a stator 5 fixed on the housing, and a rotor 9 rotatably mounted on the housing about an axis of rotation 10. A can 11 is fixed on the stator, radially between the stator and the rotor. At least one annular seal carrier 12 is fixed on the motor housing radially inside the can, in the region of an axial stator end 13. At least one annular seal 14, supported radially and axially on the seal carrier, seals off a rotor space 15 from a stator space 16. A coolant 17 can flow through the stator space. The stator space has a main region 18, which is axially adjacent to the stator, and an annular region 19, which extends from the seal along the seal carrier and merges into the main region at a distance from the seal, and the seal has an annular main body 20 and a circumferential sealing lip 21, which projects radially outward from the main body and axially toward the annular region. The seal may have a further supporting section supported radially on the seal carrier. The design improves the tolerance compatibility of the canned motor.
