A lift drive system for an energy storage and delivery system includes an electric motor that rotates a driven shaft, a brake assembly for selectively braking the rotation of the driven shaft, and optionally includes a clutch selectively operable to decouple the electric motor from the driven shaft. A steel ribbon is disposed at least partially about and in contact with the driven shaft, where rotation of the driven shaft by the electric motor causes linear movement of the steel ribbon. The steel ribbon can connect at one end to an elevator cage assembly and at an opposite end to a counterweight.

A scooter motor includes a stator unit, a rotor unit and a brake unit. The stator unit is fixedly mounted on the fixed shaft of the motor, and the rotor unit is rotatably mounted on the fixed shaft. The brake unit includes a friction plate component and an electromagnetic clutch component. The electromagnetic clutch component is configured to drive the friction plate component to press to brake. According to the embodiment of the present invention, the scooter motor drives the rotor unit to rotate by the cooperation between the stator unit and the rotor unit to drive the scooter, additionally, the stator unit controls the rotation of the rotor unit by using the friction plate component and the electromagnetic clutch component to realize the braking of the scooter.

The driving apparatus for a washing machine according to the present invention includes a clutch housing including a washing shaft and a dewatering shaft penetrating the inside; an annular clutch holder installed in the lower part of the clutch housing; a clutch lever hinge-coupled to the clutch holder, including an upper rotation part and a coupler receiving part; a driving lever having a lever arm interlocking with the upper rotation part of the clutch lever; a clutch coupler laid on the upper part of the coupler receiving part performing up and down spline movement by the coupler receiving part; and a motor assembly coupled to the lower part of the clutch holder, including a stator assembly and a rotor assembly.

A portion of ankle movement can be harnessed into stored energy that can be released for various purposes, such as to assist in movement or to charge a battery. This harnessing can be achieved in various manners. In one example manner, an offset pulley component can transfer ankle movement to a generator in a shoe insole. In another example manner, a slider can cause a brace arch to match an ankle arch such that the movement is appropriately harnessed.

Vehicular front axle powertrain, which uses an electric motor with an external rotor is for driving and braking of the front axles of vehicles with wheels which also or only use electrical power. It consists of an electric engine (1) with an external rotor or rotor extension (1.2), which is also a generator working as a brake. The rotor or rotor extension (1.2) connects to a clutch (3), which guards against overload and may have a disc brake (3.I) mounted, which carries excess braking force. The clutch (3) connects to an internal joint (4), which connects to a shaft (5), which has an external homokinetic joint (6) with a hub shaft (6.2) for the vehicle's wheel. Rotational energy goes from the electric motor (I) without mechanical losses to the hub shaft (6.2) and back, while the hub shaft (6.2) can move relative to the stator in the (SA) and (SB) directions.

A wearable system, such as a footwear system, can employ a generator. The generator can be powered by human movement, such as movement of knee as a person walks or runs. When the knee resets, it can be desirable to have a relatively equal gear ratio to achieve near natural movement. Conversely, it can be desirable to have a high gear ratio when the knee pushes off to achieve high generator rotation to produce a high amount of power. This can be achieved with employment of a wearable planetary gear set configuration In practicing this wearable planetary gear set, torque can be provided from the source (e.g. human ankle joint) when power negative and not at other times during a movement cycle, meaning energy can be harvested from the walking motion without inducing additional burden to the device wearer.
