Motor control systems and methods for micromobility transit vehicles are provided. A micromobility transit vehicle may include an electric motor configured to drive a rotation of a wheel. The electric motor may include a plurality of windings and a plurality of switching circuits. The switching circuits may be configured to selectively direct current from a power supply through the windings to generate a torque by the electric motor to drive the rotation of the wheel in response to associated control signals. The switching circuits may be configured to passively bypass the windings in response to an interruption of the control signals. Depletion of the power supply may result in the interruption of the control signals.

A kick-scooter having an electric-motorized drive, a footboard, a rear wheel arranged on the footboard, a steering assembly, and a front wheel connected to the steering assembly to pivot in unison with the steering assembly about an inclined steering assembly axis.

The invention relates to a scooter (10) including: a frame (12); a front wheel (20) and a rear wheel (22) attached to the frame; a motor (24) configured for driving into rotation at least one of the front and rear wheels; and a unit (26) for controlling the motor. The invention is characterized by the fact that the unit for controlling the motor includes: acceleration detection means for detecting an acceleration phase of the scooter; deceleration detection means for detecting a deceleration phase of the scooter; the control unit being configured for actuating the motor when a deceleration phase having a period at least equal to a first predetermined threshold has been detected by the deceleration detection means after detection of an acceleration phase by the acceleration detection means.

A wheel hub motor includes a shaft, a stator unit and a rotating unit. The stator unit includes a coreless stator set. The rotating unit includes a rotating seat set sleeved on the shaft, a bearing set, and two rotor sets fixedly mounted to the rotating seat set. The rotating seat set defines a bearing mounting space adjacent to the shaft and receiving the bearing set therein, and a rotor space radially spaced apart from the bearing mounting space and receiving the rotor sets therein. The coreless stator set is disposed between the rotor sets such that, when being energized to generate a magnetic field, the rotor sets rotate about the shaft so as to drive the rotating seat set and the bearing set to rotate.

A vehicle having an electrical drive wheel hub system (30) and the hub system incorporated in the vehicle has a wheel hub (18) driven by an electric motor (31) formed by a brushless DC motor having stators (40) and rotors (42). The electric motor is arranged to drive an epicyclic gear system (32) which provides a reduction gear arrangement to drive the hub (18). Located entirely within the periphery of the stator is power circuitry and control circuitry for the electric motor, the circuitry being provided on toroidal printed circuit boards (70, 71).

A human power conversion system incorporates two or more electric machines to aid in the powering of a vehicle through energy conversion. A first electric machine is coupled with the human powered input and acts as a generator when a human power input is not sufficient to produce electrical power that is provided to a second electric machine that propels the vehicle. The vehicle may be a bicycle and the first electric machine may be coupled to the crank. A bi-coupled electric machine including the first and second electric machines with a common rotor or stator may be employed and coupled to the crank and/or the driven wheel. Power produced by the first electric machine may be provided directly to the second machine or may be stored in a battery and used to propel the vehicle or power other electronic components.
