furthermore, the winding drum is connected with the amplitude plates at the two ends in a welding or threaded mode;
furthermore, the web is of a structure with an extending through hole in the center, a sliding bearing is arranged outside the extending part, and a bearing connected with the winding drum main shaft is arranged in the extending through hole;
furthermore, a bearing gland is arranged outside the sliding bearing and is fastened with the sliding bearing through a screw;
in the embedded electric winch, permanent magnetic steel is arranged on the inner wall of a winding drum to form a rotor, a winding coil is arranged on a main shaft to form a stator, and the permanent magnetic steel has N level and S level; the stator is composed of three-phase windings, three-phase winding coils of the stator are electrified, the N-level winding, the S-level winding and the three-phase winding generate a three-phase rotating magnetic field, the rotor is a permanent magnet, and the magnetic level is fixed; the rotating magnetic field synthesized by three-phase symmetrical current and the magnetic field generated by the permanent magnetic steel interact to generate torque, and the winding drum is driven by magnetic force to rotate synchronously.
Further, the rotation speed of the drum is controlled by the drive control device, and the rotation speed N =60f 1/p.
When a winding coil on the winding drum main shaft is electrified, the inner ring of the bearing in the central through hole of the web plate does not rotate in the process of pulling the winding drum to rotate by magnetic force, so that the winding drum main shaft is fixed; the bearing in the through hole in the center of the web plate rotates, so that the web plate rotates along with the outer ring, and the web plate drives the winding drum to rotate; the amplitude plate is arranged in the sliding bearing, the inner ring of the sliding bearing rotates, and the outer ring does not rotate, so that the amplitude plate rotates in the sliding bearing, and the rack connected with the outer ring of the sliding bearing is kept fixed.
The principle of the utility model is that: the motor is embedded in the inner wall of the winch drum, and the principle of an outer rotor permanent magnet synchronous motor is adopted, so that the drum is driven by magnetic force to rotate synchronously.
The utility model has the advantages that the volume is reduced by adopting the structure of the motor embedded winch; the technical defects that the original electric winch is large in size, heavy in weight, complex in structure, incapable of being suitable for occasions with small occupied area requirement and light in weight are overcome.
