Claims61
An electro drive comprising a stator, a rotor, and a single rotor bearing, said rotor bearing being axially arranged within the axial length of the rotor, wherein said rotor is rotatably journalled exclusively by means of said rotor bearing, and said rotor bearing is held between portions of said stator.
An electro drive comprising:
- a rotor;
- a rotor bearing which is axially arranged within the axial length of the rotor;
- and
- a stator comprising axially offset portions with fitting surfaces, said rotor bearing having an outer race held between said fitting surfaces for mutual radial and axial centering of said rotor and said stator.
An electro drive comprising:
- a stator;
- a rotor with a threaded sleeve in which a threaded rod is axially displaceable;
- a rotor bearing;
- and
- at least one bobbin comprising a projection which is adapted to engage in a groove of said threaded rod for rotationally locking said threaded rod.
An electro drive comprising a stator, a rotor, and a single rotor bearing, said rotor bearing being axially arranged substantially in center of the axial length of the rotor, wherein said rotor is rotatably journalled exclusively by means of said rotor bearing.
An electro drive comprising:
- a rotor;
- a rotor bearing which is axially arranged within the axial length of the rotor;
- and
- a stator comprising axially offset portions with fitting surfaces, said rotor bearing being held between said fitting surfaces of said stator for mutual radial and axial centering of said rotor and said stator;
- wherein said stator includes mounting flanges provided on said stator and holders for a connector socket for receiving the plug of a connecting cable.
An electro drive comprising a stator, a rotor, and a rotor bearing, said rotor bearing being axially arranged within the axial length of the rotor, said stator including stator plates with mounting flanges arranged substantially in the center plane of said rotor.
