A rotor for an electrical axial flux machine that can be operated as a motor and/or generator includes a support, a plurality of magnet elements arranged against, on, or in the support and running radially from the interior outward. The magnet elements are magnetized in a circumferential direction and arranged individually or in groups in series around the circumference with alternating opposing magnetization directions. A plurality of flux conduction elements which conduct the magnetic flux are arranged against, on, or in the support and around the circumference, between the magnet elements. At least one conduction element arranged between two magnet elements is formed by a plurality of individual flux conduction elements, the individual flux conduction elements being formed such that they conduct the magnetic flux tangentially in a circumferential direction and block the flux in a radial direction

Systems and methods relate to a vertical takeoff and landing (VTOL) platform that can include a stator and a rotor magnetically levitated by the stator. The rotor and stator can be annular, such that the rotor rotates about a rotational axis. The stator can include magnets that provide guidance, levitation, and drive forces to drive the rotor, as well as to control operation of rotor blades of the rotor that can be independently rotated to specific pitch angles to control at least one of lift, pitch, roll, or yaw of the VTOL platform. Various controllers can be used to enable independent and redundant control of components of the VTOL platform.

An electric drive system including: a rotary motor system including a hub assembly, a first rotating assembly, a second rotating assembly, and a third rotating assembly, wherein the hub assembly defines a rotational axis about which the first rotating assembly, the second rotating assembly, and the third rotating assembly are coaxially aligned and are capable of independent rotational movement independent of each other; a multi-bar linkage mechanism connected to each of the first and third rotating assemblies and connected to the hub assembly and constraining movement of the hub assembly so that the rotational axis of the hub assembly moves along a defined path that is in a transverse direction relative to the rotational axis and wherein the multi-bar linkage mechanism causes the rotational axis of the hub assembly to translate along the defined path in response to relative rotation of the first rotating assembly and the third rotating assembly with respect to each other.

An axial flux rotary electric machine including at least one stator and at least one rotor that are arranged along an axis of rotation of the machine, the rotor including a rotor mass and housings created in the rotor mass, the housings defining magnetic poles of the rotor, each of the housings being able to contain or not contain at least one permanent magnet.

A brushless DC motor (BLDC) includes a stator having a ring-shaped body with multiple stator posts extending axially outward from the ring-shaped body. A plurality of stator windings are each wound about a corresponding one of the stator posts. A rotor support structure is positioned radially inward of the multiple stator posts. A rotor including a shaft is received in the rotor support structure. A first rotor disk is fixed to a first end of the shaft.

Systems and methods of the inventive subject matter are directed to control systems that create virtual mass in a haptic feedback system. Embodiments include a jog knob coupled with a PCB stator motor such that the PCB stator motor can be controlled to give the jog knob a feeling of mass that is different from its actual mass. Thus, a system of the inventive subject matter can be configured to continue a rotation as if it has a higher mass than it actually has, resulting in smoother rotations that last longer. This functionality can be useful to, for example, remotely control a camera's movements while still giving a user the feel of a comparable mechanical system.
