A lubricant supported electric motor includes a stator extending along an axis and a rotor rotatably disposed in surrounding and spaced apart relation about the stator to define at least one support cavity. A lubricant is disposed in the support cavity for supporting the rotor about the stator. A rim is fixedly connected to the rotor and forms a surrounding relation with the rotor and the stator. Thus, in a first aspect, rotation of the rotor is directly transmitted to the rim such that the rim rotates in accordance with rotation of the rotor. According to another aspect, the rotor is rotatably disposed within the stator and a planetary gear reduction mechanism is operably interconnected to the rotor, the stator and the rim and is configured to rotate the rim in response to rotation of the rotor within the stator.

The application relates to an electromagnetic compatibility technology of an aviation power electronic device, in particular to an aviation SiC motor driver electromagnetic compatibility optimization method and system. By defining a regulation node and extracting physical boundary parameters under severe working conditions, a planning model is constructed to maximize the tolerable interference wave fluctuation amplitude, and three-level boundaries covering transient ringing suppression, frequency band radiation suppression and thermal stress distribution are output. Cross verification is used to obtain a balance coefficient. In a deep full connection mapping network combined with a Monte Carlo tree search mode, an optimization instruction sequence is generated by considering the suppression effect and regulation cost. In real-time operation, a layered retreat mechanism is started through monitoring of the conduction emission margin, and is differentiated according to the action sensitivity and is sequentially restored. Finally, the three-level boundary balance coefficient is updated by using the measured spectrum deviation feedback, and an electromagnetic compatibility evolution technical scheme covering the whole life cycle of the device is formed.

The lubricant-supported electric motor includes a stator having an outer raceway and a rotor extending along an axis and rotatably disposed within the stator. The rotor has an inner raceway spaced apart from the outer raceway to define a gap between them. Lubricant is disposed in the gap to support the rotor within the stator. At least one of the outer or inner raceways may be radially movable toward or away from the other to adjust the gap and optimize the operation of the lubricant-supported electric motor.

This invention discloses a Maxwell force-driven three-degree-of-freedom electromagnetic actuator and its control method. Four sets of permanent magnets are evenly distributed around the mover, and the permanent magnets are respectively connected to magnetic guide shoes and stator magnetic arms located obliquely above and below the side wall of the mover. An excitation coil is wound on the stator magnetic arm, which is connected to a magnetic guide base. The magnetic guide base is connected to a magnetic guide column, which extends into the interior of the mover and is fixed in the middle of a flexible diaphragm. The flexible diaphragm is connected to the mover. The permanent magnets, magnetic guide shoes, stator magnetic arms, magnetic guide base, and magnetic guide column together constitute a magnetic circuit system, enabling the mover to simultaneously respond to three independent current excitation modes, realizing integrated parallel drive of rotation around the X-axis and Y-axis and translation along the Z-axis. This invention solves the problems of structural redundancy, lack of degrees of freedom, contradiction between motion range and linear drive, and control coupling in existing electromagnetic actuators through the design of "three-degree-of-freedom integrated magnetic circuit topology" and "misaligned mover-stator configuration".
