[0050] The utility model is mainly designed from the perspective of mechanical structure, and no changes are made to the circuit, and existing technologies are used. For example, the interior of the installation frame 14 in the housing 1 is used to install components such as batteries and control modules, and the batteries and control modules can be installed in the installation frames 14 on both sides respectively. Among them, the motor main shaft 3 is a hollow shaft, and the wiring harness of the rotor mechanism (the wiring harness connected to the coil of the rotor winding 42) passes through the hollow shaft and is connected to the battery and the control module, and the wiring harness of the control module also passes through the hollow shaft and is connected to the battery on the other side.

[0051] A unicycle with a brushless motor usually includes a stator mechanism and a rotor mechanism, wherein a (winding) coil is provided on the stator mechanism for generating magnetic force by energizing.

[0052] The unicycle generally includes the following structures. The present invention does not make any improvements to the control structure principle of the unicycle, and all existing technologies are adopted:

[0053] Stator structure: The stator is the stationary part of the motor, usually composed of a set of coils wound with copper wire. When current passes through, a field is generated in the coils.

[0054] Rotor structure: The rotor is the rotating part of the motor and is usually composed of magnets made of strong magnetic materials (such as permanent magnets 53).

[0055] Electronic controller: The operation of the motor is controlled by the electronic controller. The electronic controller controls the current changes in the coil by regularly releasing and shutting off the current, thereby generating a rotating magnetic field and driving the rotor to rotate.

[0056] Sensors: In order to achieve closed-loop control and maintain balance, unicycles generally have built-in sensors such as accelerometers and gyroscopes to monitor the vehicle's tilt and acceleration, which are then corrected through an electronic controller.

[0057] When current passes through the coil on the stator, the magnetic field generated interacts with the magnet on the rotor, generating an electromagnetic force to rotate the rotor. The electronic controller can adjust the direction of the magnetic field and the speed of rotation by accurately controlling the magnitude and direction of the current, thereby achieving precise control of the motor's output force. At the same time, the control system can make timely adjustments to keep the vehicle balanced by detecting the tilt state of the vehicle through sensors.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
