The motor assembly includes a stator, a rotor including a rotor shaft including a metallic material and configured to be rotatable by electromagnetic interaction with the stator, a hub including a plastic material and including a hollow portion configured to allow the rotor shaft to pass therethrough, and a shaft coupling member positioned between the hollow portion and the rotor shaft and including a plastic material different from a plastic material forming the hub. | 2021-12-30 |
| 20210408869 | Universal Shaft with a Generator for Generating Electricity - A universal shaft with a generator for generating electricity with the generator being driven by a cardan error occurring with a rotation of the universal shaft. | 2021-12-30 |
| 20210408870 | Monitoring Systems for Shipping Containers - Interested parties would like to track the location of one or more towed transport platforms continuously when they are in motion. Existing monitoring systems are powered by a combination of solar power, batteries, and intermittent tractor platform power for electrical power. All of these power sources have limitations in providing power when a towed transport platform is in motion. Solar power is not available at night. Batteries run out of energy and must be recharged. Tractor platform power is not always available to a towed transport platform. The embodiments of the invention convert the kinetic energy of a moving towed transport platform into electrical power, providing continuous power for a monitoring system to operate. | 2021-12-30 |
| 20210408871 | Electric Motor - An electric motor arrangement for a pump includes power electronics for control of the electric motor driving the pump. For cooling of the electric motor and/or the power electronics, media from a pump chamber of the pump casing flows through a suction-side connection, a coolant channel associated with the power electronics and/or of the electric motor, to a pressure-side connection of the pump. The flow in the coolant channel may be controlled by a thermostat valve. | 2021-12-30 |
| 20210408872 | MOTOR - The present invention may provide a motor including a rotary shaft, a yoke coupled to the rotary shaft, a stator disposed between the rotary shaft and the yoke, a first magnet and a second magnet disposed in the yoke, and a circuit board on which a first Hall sensor is disposed to correspond to the first magnet and a second Hall sensor is disposed to correspond to the second magnet, wherein the second magnet includes a plurality of split magnets and one index magnet, a width of the split magnet in a circumferential direction is the same as a width of the index magnet in the circumferential direction, each of the split magnets and the index magnet are formed by combining a first pole and a second pole, a width of the first pole of the split magnet in the circumferential direction is the same as a width of the second pole in the circumferential direction, and a width of the first pole of the index magnet in the circumferential direction is different from a width of the second pole in the circumferential direction. | 2021-12-30 |
