Problems solved by technology

In the normal temperature state, excess voltage is applied to the winding, and the excess energy will cause the temperature of the winding to rise rapidly, which in turn will lead to an increase in resistance, thereby reducing the winding current, resulting in a large amount of power being wasted, and severe heat will lead to a reduction in the life of the brake. small, even ineffective

Abstract

The invention discloses an electromagnetic brake control circuit and an electromagnetic brake controller. The electromagnetic brake control circuit comprises an excitation coil, a control circuit and a switch circuit, wherein the control circuit outputs a brake turning-on signal or a brake keeping signal; the switch circuit receives the brake turning-on signal or the brake keeping signal, performs turning on or turning off, and controls the magnitude of currents passing the excitation coil; the excitation coil controls the armature of a brake to loosen a brake disc when the control circuit outputs the brake turning-on signal; the excitation coil controls the armature of the brake to be separated from the brake disc when the control circuit outputs the brake keeping signal. The electromagnetic brake control circuit has the advantages that the heat generation quantity of the electromagnetic brake is reduced by using the current control manner, and the service life of the brake is prolonged.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to an electromagnetic brake control circuit and an electromagnetic brake controller. Background technique [0002] The electromagnetic brake device is widely used in various transmission devices that need to maintain the position after power failure. The electromagnetic brake is mainly composed of an excitation coil, a spring, and an armature. When the excitation coil is energized, a magnetic field is generated, and the armature is attracted to loosen the armature and the brake disc. Open; when the excitation coil is powered off, the magnetic field disappears, and the armature is pushed to the brake disc by the action of the spring, generating friction torque and braking. At present, the control method of the electromagnetic brake adopts the voltage control mode. The winding of the electromagnetic brake is usually made of copper. As the temperature rises, the resis...
