Electromagnet used for electromagnetic brake

Abstract

The invention relates to the field of electromagnetic brake, in particular to an electromagnet used for an electromagnetic brake. The electromagnet comprises a mandrel and a control circuit, a threadshaft is mounted at one end of the mandrel, a pressing sleeve is mounted on one side of the mandrel, one side of the pressing sleeve is in threaded connection with a thread wire, one side of the mandrel is provided with an armature, the pressing sleeve is mounted on one side of the armature through the thread wire, a yoke is arranged on one side of the armature, a coil is mounted in the yoke, insulation paint is arranged between the yoke and the coil, a disc spring is mounted outside the mandrel, a protection shell is mounted outside the disc spring, a pressure sensor is mounted on one side ofthe disc spring, a sleeve rod is arranged on the other end of the mandrel, the outer wall of the sleeve rod is in threaded connection with a locking nut, the disc spring comprises a disc spring leverarm backrest side and a disc spring opening side, and the electromagnet has the beneficial effects that the power of a transformer can be reduced, the volume and the weight of a control box can be reduced, an overcurrent relay switches a high-voltage circuit into a small-voltage circuit to be kept, and temperature rise of the electromagnet coil can be reduced.

Description

technical field [0001] The invention relates to the field of electromagnetic brakes, in particular to an electromagnet used for electromagnetic brakes. Background technique [0002] Due to the advantages of simple structure, fast response, convenient maintenance, and low cost, electromagnetic brakes can replace hydraulic brakes in some working conditions. At present, the braking force of the brake is mainly maintained by regularly checking the wear of the friction plate, and the actual braking force of the brake cannot be known, which is prone to slipping due to untimely maintenance. [0003] When the electromagnetic brake is working, it generally works in the way of high voltage pull-in and low voltage maintenance. When the high voltage pulls in, the power is high, and the coil is easy to heat up. At present, in order to reduce the heating of the electromagnet coil, the heating of the electromagnet coil is mainly controlled by the time relay to control the high voltage pu...

Problems solved by technology

[0006] The purpose of the present invention is to provide an electromagnet used in electromagnetic brakes to solve the problem of the electromagnet brake opening power components proposed in the background technology. Due to the high power, the brake is easy to generate heat under high-frequency working conditions, and the coil is easy to burn out. When the electromagnetic brake is working, the noise is relatively large when the armature collides with the yoke during the pull-in.
