Abstract

The invention relates to an unlocking holding double-coil electromagnet and an electrifying unlocking holding method of the double-coil electromagnet. The coils comprises an actuation coil and a holding coil; an electromagnet body comprises a microswitch, the microswitch comprises a common contact, a normally closed contact, an action contact and a push rod; one end of the action contact is connected with the common contact, the other end of the action contact is connected with the normally closed contact, and one end of the push rod is contacted with the action contact; the microswitch is arranged at one side of a magnetic yoke, the other end of the push rod is opposite to an armature, and the armature can push the push rod to break the connection between the common contact and the normally closed contact under the state that the armature is attracted; one ends of the actuation coil and holding coil are connected with an anode of a power supply; the other ends of the actuation coil and holding coil are respectively connected with the common contact and the normally closed contact in a one-to-one correspondence manner; the common contact is connected to the negative pole of the power supply. The method solves the problems of serious heating, high possibility of long-time working damage and resource waste of a prior double-coil electromagnet.

Description

technical field [0001] The invention relates to an unlocking and holding double-coil electromagnet and an energized unlocking and holding method for the double-coil electromagnet. Background technique [0002] The electromagnet is used as a pin-type braking device with power-on disengagement (release) and power-off spring brake. It has the advantages of compact structure, convenient installation, wide adaptability, low noise, sensitive action, and reliable braking. It is widely used in aviation and aerospace. and other fields of electromechanical equipment. According to the product characteristics of the electromagnet and the electromagnetic theory, the electromagnetic force generated by the electromagnet is inversely proportional to the square of its air gap. Therefore, theoretically, under the initial current value, if the movable parts of the electromagnet can move, they must be able to move in place. In other words, for maintaining the pull-in state of the movable parts...
