The present invention relates to the technical field of electric push rods. Disclosed is a novel intelligent electric push rod, specifically comprising an alternating-current
permanent magnet motor and a push rod driven thereby. The alternating-current
permanent magnet motor is provided with Hall sensors for detecting the position of a rotor of the alternating-current
permanent magnet motor; and the electric push rod comprises at least one of an
electromagnetic brake control unit, a
wireless communication or
wired communication unit, a power-off compensation braking unit, and a push rod
stroke position detection unit. The
electromagnetic brake control unit in the present invention achieves, in an
electromagnetic brake manner, holding and braking of the push rod when current flows through windings of the alternating-current permanent
magnet motor, thereby solving the problem of a self-locking failure caused by the reduction of a
friction coefficient of a screw pair; additionally, the push rod
stroke position detection unit achieves detection of the upper (lower) limit position of the push rod
stroke, thereby avoiding the problems caused by a mechanical
limit switch, and effectively improving the service life of a product; and the
wireless communication or
wired communication unit in the present solution can reduce the number of wire harnesses, thereby simplifying an
assembly and wiring mode and a maintenance process.
