    摘要： Handwheel systems of the inventive subject matter can be used in a variety of different contexts, including by camera operators. Handwheel systems disclosed in this application provide haptic feedback, which requires high amounts of torque generated by a motor built into the system. PCB stator motors are implemented for their ability to generate high amounts of torque in a compact form factor. Control systems used to drive motors in these systems update at rates that are typically within range of human hearing, and because of the high torque generation, vibrations can be transferred to different components of the handwheel systems, which can cause some components to audibly vibrate. To mitigate or eliminate these audible vibrations, handwheel systems disclosed in this application incorporate adhesive tapes and bushings that prevent vibrations from passing into components that are prone to audible vibrations.

    摘要： Systems and methods for hoisting a top drive of a drilling rig. An example system includes a hoisting system having a linear electric motor operable to raise and lower the top drive. An example method includes commencing operation of a processing device to cause operation of the linear electric motor to raise and lower the top drive. The linear electric motor may have a stator connected to and extending vertically along a mast of the drilling rig, and a rotor connected to the top drive and operable to move relative to the stator. The rotor may be connected to the top drive via one or more flexible lines.

    摘要： The disclosure provides a direct drive transmission system including a mover unit and a stator unit driving the mover unit to move. The stator unit includes a stator assembly, two first end covers, and two first guide rails. A side of the first end cover close to the first guide rail is recessed inwardly to form a first mounting groove, and two ends of the first guide rail are respectively inserted into the first mounting groove. The mover unit includes a mover assembly, two second end covers, and two second guide rails. A side of the second end cover close to the second guide rail is recessed inwardly to form a second mounting groove, two ends of the second guide rail are respectively inserted into the second mounting groove. The stator assembly drives the mover assembly to cause the second guide rail to move on the first guide rail.

    摘要： An electric motor bicycle system with an electric motor driven gear adapted to drive a wheel gear coupled to a bicycle hub. The motor driven gear is coupled to the wheel gear with a chain. The chain may be tensioned with one or more tensioners, which allow for a tighter system geometry. The motor may be supported with a bracket adapted to mount to industry standard disc brake mounting interfaces. In some aspects, the motor driven gear is coupled to the disc mounting interface of a wheel hub. In some aspects, the electric motor bicycle system may also have a disc brake system integrated therein.
