5. Principle and Structure

The DC disc brake of the YEJ type electromagnetic three-phase ac brake YEJ clutch brake motor is mounted on the end cover of the non-shaft end of the YEJ clutch brake motor. When the brake YEJ clutch brake motor is connected to the power supply, the brake also works at the same time.

Before we use all kinds of brake YEJ clutch brake motors, we need to know the working principle of YEJ electromagnetic brake YEJ clutch brake motor first, so that we can be more familiar with it in the use process. The following author will explain the working principle of YEJ electromagnetic brake YEJ clutch brake motor. There is an electromagnetic brake at the tail of the YEJ clutch brake motor. When the YEJ clutch brake motor is electrified, it also electrifies and sucks. At this time, it does not brake the YEJ clutch brake motor. When the YEJ clutch brake motor is cut off, it also loses power. The brake is braked by the spring. A kind of
_Two AC input terminals of a rectifier bridge are connected to any two AC input terminals of the YEJ clutch brake motor and synchronously input 380 V AC with the YEJ clutch brake motor. The two DC output terminals are connected to the brake excitation coil. The working principle is that when the YEJ clutch brake motor is powered on, the DC power of the coil will generate suction to separate the two friction surfaces at the tail, and the YEJ clutch brake motor will rotate freely, on the contrary, the YEJ clutch brake motor will be braked by the spring return force. The coil resistance varies from tens to hundreds of euros depending on the power of the YEJ clutch brake motor.

Due to the electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, and the electromagnetic three-phase ac brake YEJ clutch brake motor is The armature and end cover are disengaged and the YEJ clutch brake motor starts to rotate. When the power is turned off, the brake electromagnet loses the electromagnetic suction force, and the spring pushes the armature to press the brake disc. Under the action of the friction torque, the YEJ clutch brake motor immediately stops rotating.

YEJ series electromagnetic braking three-phase asynchronous YEJ clutch brake motor (referred to as brake YEJ clutch brake motor) is a derivative product formed by attaching a dc electromagnetic brake between the rear cover and the fan of the Y series (IP44) YEJ clutch brake motor. Brake and YEJ clutch brake motor matching, in which the no-load braking time is an important indicator, it directly affects the parking accuracy, for accurate positioning, prevent sliding, brake requirements of high precision equipment is particularly important. According to different frame sizes, the standard provides the corresponding static braking torque of electromagnetic brake and the no-load braking time of the YEJ clutch brake motor.

Yej-801-4 braking YEJ clutch brake motor principle: in the braking three-phase asynchronous YEJ clutch brake motor tail has an electromagnetic brake, when the YEJ clutch brake motor is energized, it is also energized suction, then it does not brake the YEJ clutch brake motor;When the YEJ clutch brake motor power off it is also power off, holding brake in the spring under the action of the YEJ clutch brake motor brake.Brake YEJ clutch brake motor is used to control the YEJ clutch brake motor inertia, so that it meets the requirements of accurate ***, to achieve automatic mechanical work.Applicable to all kinds of mechanical rotation system clutch, inching, speed change, reversing, etc.

the braking time of the ordinary YEJ clutch brake motor electromagnetic loss brake is often used to form a complete set of YEJ series electromagnetic brake YEJ clutch brake motor with the Y series YEJ clutch brake motor.As the brake voltage is generally 170V and 96V dc, it needs to be rectified by half-wave rectifier.The half-wave rectifier is directly installed in the YEJ clutch brake motor junction box, and its input terminal is connected to two terminal blocks of the YEJ clutch brake motor.

The wiring mode of ordinary YEJ clutch brake motor is shown in figure 1.When the YEJ clutch brake motor is power off, the ac side of the half-wave rectifier is also power off, while the YEJ clutch brake motor rotor is still slowing down and rotating, and the phenomenon of regenerative power generation is formed.At this time, the YEJ clutch brake motor will continue to supply power to the rectifier with a gradually weakening voltage, and then the brake coil will generate a gradually weakening excitation current.The magnetic field generated by this current will prevent armature from detaching, thus extending the braking time and affecting the accuracy of braking and positioning.For example, the measured time of YEJ100 YEJ clutch brake motor from power failure to complete YEJ clutch brake motor braking is 1.56s.One of the two ways to shorten the braking time of YEJ clutch brake motor is to add a switch synchronizing with the YEJ clutch brake motor power on the dc side of the rectifier to make the ac and dc side of the brake power off at the same time, as shown in figure

When the YEJ clutch brake motor is power off, the voltage generated by the above regenerative power generation phenomenon no longer forms a loop for the brake, and there is no current in the brake coil. The armature will instantly disengage and shorten the braking time.Although this method has a good effect, two wires must be drawn from the dc side of the rectifier in the YEJ clutch brake motor junction box to the auxiliary normally open contact of the contactor QS, which is very inconvenient in practical operation.

6. Mounting Mode

In order to further understand the defects in YEJ clutch brake motor operation, check test can be done before disassembly if possible. For this purpose, the electromagnetic three-phase ac brake YEJ clutch brake motor with load test run, detailed inspection of each part of the YEJ clutch brake motor temperature, sound, vibration and other conditions, and test voltage, current, speed, and so on, and then disconnect the load, a separate no-load inspection test, measurement of no-load current and no-load loss, make a record.

This piece of brake is composed of high friction coefficient and long life material, the number of braking up to 1,000,000 times, even at 75℃ high temperature still can be used at full load;Brake YEJ clutch brake motor structure is simple, easy to install, plus small volume, light weight, even in a small space can also be successfully installed;The braking YEJ clutch brake motor USES AC power, which is converted by the rectifier and supplied to the DC braking coil, so that the braking noise of the braking YEJ clutch brake motor can be reduced to *** without electromagnetic sound. No matter forward or reverse, the braking action can be effectively completed.As the power supply of the braking YEJ clutch brake motor is supplied by the YEJ clutch brake motor tap, different voltages can be used according to different wiring methods, with a variety of voltage performance;Brake YEJ clutch brake motor action is sensitive, no no-load torque, can achieve fast braking in a short time, and have enough braking torque.Brake parts sufficient, with perfect after-sales service, *** convenient
