AC brake coil, winding device and process

Abstract

The present application relates to an AC brake coil, which includes a skeleton, a winding and a protective cover. There are two skeletons, and the outer circumference of any skeleton is provided with a ring groove. The ring groove extends for one week along the circumference of the skeleton. The ring groove is used for winding the wire to form a winding, and a complete wire is wound on a skeleton first. In the ring groove of another skeleton, two windings are formed by winding in the ring groove of another skeleton, and a connecting wire of preset length is left between the two windings. One end of any skeleton is also provided with a guide groove, and the guide groove is connected. The ring groove is used for the wire to protrude; and when the guide grooves of the two skeletons have the same orientation, the winding directions of the windings on the two skeletons are consistent. The application has the effect of indicating the winding direction of the winding through the guide groove, so as to facilitate the installation of the coil on the iron core.

Description

technical field [0001] The present application relates to the field of motor brakes, and in particular, to an AC brake coil, a winding device and a process. Background technique [0002] The brake motor has the characteristics of rapid braking, and a brake is usually attached to the rear end cover of the brake motor. [0003] The brake includes a brake disc, an armature, a spring and an electromagnet. The brake disc is coaxially and fixedly connected to one end of the rotor. The armature is arranged on the side of the brake disc away from the rotor, and the armature slides along the axial direction of the rotor. The spring makes the armature have pressure. To tighten the brake disc, the electromagnet is located at the end of the armature facing away from the brake disc. [0004] When the brake motor is connected to the power supply, the electromagnet is energized, and a magnetic force is generated. The electromagnet attracts the armature and compresses the spring, so that t...

Problems solved by technology

[0006] In view of the above-mentioned related technologies, the inventor believes that the direction of the magnetic field of the electromagnet is related to the winding direction of the coil, and the six coils of the electromagnet of the AC brake work at the same time. Therefore, when the six coils are installed on the iron core, It is necessary to check the extension direction of the coil head one by one to identify the winding direction of the coil and install the coil on the iron core correctly. The installation of the coil is inconvenient
