Definitions
- the invention relates to external rotor motors in a closed construction according to the preamble of claim 1.
- the invention has for its object to expand the previous uses and uses of external rotor motors, in a completely closed design, by a more effective cooling system. This object is achieved by the characterizing features of claim 1.
- the efficiency of a structural unit "electric motor-machine" or system can be significantly increased, depending on the needs of the power transmission or the system part to be driven, for example, as a hexagon, toothing, snug fit, etc., or the
- the shape of the rotating machine part for example fan blades, fan impeller, roller, roller, gear, drill bit, etc. is preserved and additional bearing, friction and force transmission losses are thus eliminated.
- the rotor (1) is rotatably arranged on the stator hollow shaft (3) with the bearing plates (6, 7) sealed to the rotor via the bearings (5) and the mechanical seals (9).
- the stator (2) which consists of the stator laminated core and the stator winding, sits on the stator hollow shaft (3).
- stator winding The electrical connection of the stator winding and the temperature sensors or thermal contacts integrated in the stator winding takes place via the connecting line (13) guided through the stator hollow shaft (3).
- the design of the winding heads (8) of the stator winding is adapted to the inner shape of the end shields (6, 7).
- End shield (6) is provided on the inside with guide vanes (15) and is designed as a pump impeller and the shape of the winding head (8) is adapted. Due to the special, coordinated shape of the bearing plate (6) with guide vanes (15) and the winding head (8), a centrifugal pump is created in the motor interior to convey the liquid.
- the bearing plate (7) on the inside is also adapted to the shape of the winding head (8) in order to achieve good washing around the winding head, a high flow rate of the liquid and thus the best possible cooling of the stator winding.
- additional cooling bores or cooling channels (17, 18) can be made along the stator winding in the axial direction or, in the case of motors with a pump integrated on both sides, also in the radial direction.
- the dust-proof cover of the mechanical seals (9) and the bearings (5), or in the reverse arrangement, - bearings (5) and mechanical seals (9) - which can be selected depending on the type of bearing or need, is carried out via the bearing cover (16).
- the cooling and lubrication of the bearings and mechanical seals is carried out by the liquid.
- the liquid distribution in the motor ie the separation into a motor suction side or motor pressure side, takes place via the stator hollow shaft (3), which is sealed at both ends by the plugs (11, 12) .
- the radial bores (14, 14a) are also made in the stator hollow shaft (3) for the distribution of liquid.
- Also mounted in the stator hollow shaft are one or more pressure compensation devices (4) for volume or pressure compensation of the liquid.
- the pump integrated in the motor (parts 8, 15 and 6) sucks in liquid from the stator hollow shaft (3) via the radial bores (14) and presses the liquid over the Annular gap between the rotor and the stator, as well as other cooling bores, depending on requirements, further back over the gap between the end shield (7) and the winding head (8), the radial bores (14a) into the stator hollow shaft (3).
- This embodiment is suitable for all motors in which the cooling of the stator is in the foreground and the necessary heat dissipation is possible via the rotor, to the environment or to the conveyed medium or to the machine part to be driven.
- FIG. 1 The example in FIG.
- FIG. 2 shows a motor according to the invention with additional connections (19, 20) for an external cooling system and / or an external coolant pump.
- the motor is divided into a suction and pressure side, or a liquid inlet and liquid outlet side, via the cutting disc (21).
- Fig. 3 shows a motor corresponding to Fig. 2, but with a different shape of the pump guide vane (15), the winding heads (8) and the inside of the bearing plate (7).
- FIG. 4 shows a motor according to the invention corresponding to FIG. 1, but only with a shaft end on one side as a fixed assembly point. 4, a mechanical seal and the bearing plate (7) form a unit with the rotor (1).

Abstract
Moteurs à induit extérieur du type clos, à refroidissement direct de l'empilage de tôles du stator, de l'enroulement du stator et des têtes de bobine, ainsi que de l'induit et du carter, et dans lesquels, contrairement aux moteurs à induit extérieur connus, un agent de refroidissement liquide est utilisé. Il s'ensuit une augmentation notable du rendement par rapport aux moteurs à induit extérieur connus et, en raison de la surpression constante du liquide à l'intérieur du moteur par rapport à la pression ambiante, les moteurs décrits s'utilisent avec fiabilité pratiquement sans limitation dans tous les domaines de la technologie d'entraînement et dans les conditions d'emploi les plus sévères. Les flasques sur l'intérieur du moteur sont adaptés à la forme des têtes de bobine de l'enroulement du stator, au moins un des flasques étant pourvu d'aubes directrices. Une pompe centrifuge est ainsi ménagée à l'intérieur du moteur hermétiquement blindé et entièrement rempli de liquide, ladite pompe servant à propulser et à faire circuler le liquide. La pompe aspire le liquide depuis l'arbre creux du stator et le refoule à nouveau dans ledit arbre creux en passant par le passage annulaire, entre le rotor et le stator, ainsi que par d'autres alésages de refroidissement si nécessaire, sur le côté opposé de la pompe. Les moteurs exigeant un degré de refroidissement élevé sont divisés en un espace d'aspiration et un espace de refoulement par une plaque séparatrice, dans l'arbre creux du stator, et sont reliés à un système de refroidissement externe et/ou à une pompe à refrigérant externe.
