Power generation and brake apparatus, and foot treading fitness equipment

Abstract

The present invention discloses a power generation and brake apparatus disposed on a shaft. The power generation and brake apparatus comprises a wheel body disposed to the shaft, wherein the wheel body comprises an outer ring portion, magnets and an inner ring portion; a stator unit disposed to the shaft, wherein the stator comprises a stator main body, tooth portions and coils wound to the tooth portions, and when the wheel body rotates, the magnets rotate relative to the stator unit to generate alternating current; a rectifier unit connected to the stator unit so as to convert the alternating current into direct current; a control panel connected to the rectifier unit; a waveform generation unit connected to the control panel so as to generate a reverse torque input signal; a DC source adjusting unit connected to the waveform generation unit; and a brake unit disposed to the stator main body, wherein the brake unit receives the direct current and the reverse torque input signal and has a brake main body, another tooth portions and another coils wound to the another tooth portions, and the brake unit brakes the wheel body. Therefore, vibration is suppressed and noise is reduced.

Description

technical field [0001] The present invention relates to a power generation device, more specifically, to a power generation and braking device that suppresses vibration to reduce electromagnetic noise, and a foot exercise equipment with the aforementioned power generation and braking device. Background technique [0002] Such as figure 1 As shown, the well-known power generation device 1, by rotating the wheel body 2, the power generation unit 3 continuously generates alternating current, and after the rectifier 4 converts the alternating current into direct current, it supplies the control panel 5; however, the control panel 5 only requires a small amount of power It can be operated, so the excess power is consumed through the high-power resistor 6. Therefore, there is a problem of power waste. [0003] In addition, the well-known power generation device 1 will set the magnet of the wheel body 2 and the teeth of the power generation unit 3 in an unpaired manner to reduce ...

Therefore, there will be a problem of power waste

[0003] In addition, the well-known power generation device 1 will set the magnet of the wheel body 2 and the teeth of the power generation unit 3 in an unpaired manner to reduce the apparent degree of cogging torque; however, when the magnet of the wheel body 2 and the tooth portion of the power generation unit 3 When the teeth are arranged in an unpaired manner, due to the uneven distribution of internal torque, it is easy to generate vibration in the direction of rotation, so that the power generation device 1 is easy to be damaged, and electromagnetic noise will be generated
