ELECTRIC POWER GENERATION AND BRAKE DEVICE

摘要

An electric power generation and brake device disposed on a shaft includes: a wheel installed to the shaft and including a magnet; a stator unit installed to the shaft and including a stator body, a serrated portion and a coil, such that when the wheel rotates, the magnet rotates with respect to the stator unit to generate an alternating current; a rectifier unit connected to the stator unit for converting the alternating current into a direct current; a control panel connected to the rectifier unit; a waveform generator unit connected to the control panel for generating an inverted torque input signal; and a brake unit for receiving the direct current and the inverted torque input signal, and including a brake body, a serrated portion and a coil, and the brake unit is provided for braking the wheel, so as to resist vibration and reduce noise.

1. An electric power generation and brake device, disposed on a shaft, comprising:
a wheel movably and axially installed to the shaft and comprising:
an outer ring disposed around an edge of the wheel;an inner ring coaxially installed with the outer ring to the wheel and situated between the outer ring and an axis of the wheel; anda plurality of permanent magnets spaced with each other and installed on a side of the inner ring facing towards the axis of the wheel; a stator unit fixed to the shaft by using the axis of the wheel as the center and comprising:
a stator body disposed between the inner ring of the wheel and the axis of the wheel;a plurality of first serrated portions disposed around a periphery of the stator body and configured to be corresponsive to the permanent magnets respectively; anda plurality of electric generating coils wound around the first serrated portions;wherein, when the wheel rotates, the permanent magnets rotate with respect to the stator unit to generate an alternating current;
a rectifier unit electrically coupled to the stator unit to convert the alternating current into a direct current; a control panel electrically coupled to the rectifier unit; a waveform generator unit electrically coupled to the control panel and generating an inverted torque input signal; a DC power regulator unit electrically coupled to the waveform generator unit; and a brake unit fixed to the shaft or the stator body by using the axis of the wheel as a center and electrically coupled to the DC power regulator unit to receive the direct current and the inverted torque input signal, and the brake unit comprising:
a brake body disposed between the outer ring and the inner ring of the wheel;a plurality of second serrated portions disposed around the periphery of the brake body and configured to be corresponsive to the outer ring of the wheel; anda plurality of brake coils wound around the second serrated portions respectively; wherein, the brake unit is provided for braking the wheel.
