摘要： The current subject matter describes a device and system including one or more movable arms containing one or more magnets that are caused to move relative to a non-ferrous material by motion of the device to generate eddy currents that cause a braking of the device. Devices of this disclosure may include one or more trolleys that moving along a coaster track and which contain braking arms having magnets that move due to inertial force and/or can be controlled by a remote server computer based on information obtained from the one or more trolleys as they move along the coaster track.

摘要： The disclosed apparatus relates to a non-frictional, rotational, continuous energy absorbing device utilizing internal liquid cooling and having no dynamic seals. The apparatus is comprised of a rotor assembly containing magnets, cooling chambers containing magnetically driven impellers, actuators to adjust the axial positioning of said chambers, and other variations of the apparatus including an air-cooled design and additional friction braking. Braking torque is generated through shearing of eddy currents as the cooling chambers are moved axially closer to the rotor by actuators. The same action also drives magnetically driven impellers, resulting in coolant flow. Braking energy absorption increases as does coolant flow as the distance between the cooling chambers and the rotor is decreased. As the distanced between the rotor and cooling chambers increase, both energy absorption and coolant flow decrease to zero. The coolant flows from the cooling chambers to a heat exchanger to dissipate the energy.
摘要翻译：所公开的装置涉及利用内部液体冷却并且没有动态密封的非摩擦，旋转，连续的能量吸收装置。该装置由包含磁体的转子组件，包含磁力驱动的叶轮的冷却室，用于调节所述室的轴向定位的致动器以及包括空气冷却设计和附加摩擦制动的装置的其它变型组成。当冷却室通过致动器轴向更靠近转子移动时，通过涡流剪切产生制动扭矩。相同的作用也驱动磁力驱动的叶轮，导致冷却剂流动。制冷能量吸收随着冷却剂流动而减小，因为冷却室和转子之间的距离减小。随着转子和冷却室之间的距离增加，能量吸收和冷却剂流量都减少到零。冷却剂从冷却室流向热交换器以消散能量。

The rotor housing (54) has heat dissipating fins (96) accessible by the open environment whereby air movement relative to the housing caused at least by rotation of the rotor absorbs heat from the fins. The machine may bean axial flux machine, the coils being wound on bars that are disposed circumferentially spaced around a fixed axle of the machine forming a rotational axis (80) of the rotor. The machine may be a wheel motor for a vehicle, wherein the wheel is mounted directly on the rotor housing (14).

摘要： An eddy current damper has an electrically conducting body having a face, and an array of magnets extending over the face of the conducting body. Each magnet generates a magnetic field directed essentially transversely to the face of the conducting body. The magnet array generates oppositely directed magnetic fields each having a field width. At least one of the magnetic fields generated by the magnets has a field width that is smaller than a field width of an adjacent magnetic field. The conducting body may have an opening having a width that is smaller than a field width of a corresponding magnetic field.

摘要： A coil for a dynamic eddy current braking system affixed to the lower half of a vehicle wheel by two steel, yoke-shaped, end supports joined by parallel rectilinear arms, with the end supports spaced for clearance from the coil and along with thin non-magnetic sheets defining free enclosures around the coil ends, the supports having holes to inject an elastomer into the free enclosures. Seals limit the elastomer to the flat portions of the coils and plates in the zone of injection of the elastomer are immobilized in relation to the support parallel to rectilinear arms but separable from the inner wall of the support to permit thermal expansion and contraction of the coil and elastomer in the support without loss of the transmission of forces to the support occurring in the course of braking and without exaggerated transfer of forces to the support in the case of considerable heating or cooling and without detachment of the elastomer in the case of a very considerable drop in ambient temperature.
