  • Passive terminal anti-stop circuit, passive terminal anti-stop system composed of it and anti-stop method
    Patent number: 11368122
    Abstract: The present invention discloses an anti-stalling circuit, an anti-stalling system composed of same and an anti-stalling method. The anti-stalling circuit includes a motor main circuit and a control circuit; the anti-stalling system includes a substrate rotating synchronously with a passive end and the passive end anti-stalling circuit, the substrate is provided with a notch, the angle of the notch ranges from 150° to 170°, and the proximity switch SQ1 and the proximity switch SQ2 are installed at 180° on both sides of the substrate; and the passive end anti-stalling method is applied to the passive end anti-stalling system. The present invention can greatly reduce the probability of major failures caused by the stalling of a passive end of drive equipment at a limited cost.
