The invention discloses an electronic speed governor of an elevator. The electronic speed governor comprises a rack (1), a rope wheel (2), a first disc (3) and a control panel (8). The electronic speed governor synchronously outputs a first overspeed signal and a second overspeed signal during overspeed; before braking, the second disc (4) rotates by a certain angle and drives the first disc (3) to trigger a switch on the rack (1) to output a second overspeed signal. The electronic speed governor is additionally provided with a disc for speed measurement and stopping, the speed measurement is realized by detecting the on-off state of the side wall of the disc through a proximity switch when the side wall passes through the disc, the electromagnet falls down to clamp the mechanical action of the disc during overspeed, and the disc rotates to trigger the lower switch to act after the mechanical action. And the overspeed electrical switch outputs simultaneously through the lower switch and the circuit board electronic switch, so that the reliability and the braking effect are better.
本发明公开了一种电梯的电子限速器,包括机架(1)、绳轮(2)、第一圆盘(3)和控制板(8);所述电子限速器在超速时同步输出第一超速信号和第二超速信号;在制停之前第二圆盘(4)转动一定的角度并带动第一圆盘(3)去触发机架(1)上的开关输出第二超速信号。该电子限速器增加用于测速和制停的圆盘、测速通过接近开关检测圆盘侧壁的通过时的通断来测速,超速时电磁铁落下卡住圆盘的机械动作,机械动作后圆盘转动触发下部开关动作,超速电气开关通过下部开关和线路板电子开关同时输出,可靠性和制停效果更好。
