The braking motor is a fully enclosed self-fan cooled squirrel-cage three-phase asynchronous motor with additional disc dc brake. It is composed of a dc disc electromagnetic braking motor which is attached between the rear cover of Y series motors and the fan. It is a derivative of Y series.

Characteristics of the editor

It has the advantages of quick braking, simple structure, high reliability and strong versatility. In addition, the braking motor is equipped with manual release mechanism (60-90 is not designed with manual release mechanism)

Application of editing

Brake motors are widely used in a variety of mechanical equipment and transmission devices that require rapid stopping and accurate positioning. This series of braking motors are widely used in metal processing machine tools, packaging machinery, woodworking machinery, food machinery, chemical machinery, textile machinery, construction machinery and gear reducer.

Working principle editing

The dc disc brake of the brake motor is mounted on the end cover of the non-axial extension end of the motor. When the brake motor is connected to the power supply, the brake motor also works at the same time. Due to the action of electromagnetic suction, the electromagnet attracts the armature and compresses the spring, the brake disc is detached from the armature end cover, and the brake motor starts to operate. When the power is cut off, the braking motor electromagnet loses its magnetic suction, the spring pushes the armature to press the brake disc, and the braking motor stops immediately under the action of friction torque. At the same time, it also produces the corresponding YDEJ two-speed (multi-speed, far-pole ratio) motor. The braking motor power is supplied by the rectifier in the junction box of the motor, 3 kw and below are ac220v-dc99v, 4 kw and above are ac380v-dc170v (in special cases, according to the requirements of the manufacturer, such as (DC24V)) →YEJ series of electromagnetic braking motors, which can realize the rapid braking after the loss of power of the motor. The fast braking time yej2-63-90 motor is less than 0.15 seconds, and the yej-100-160 motor is less than 0.20 seconds. The braking motor can realize slow braking by changing the wiring of the junction box according to the user's requirements. The series motor has low noise and reliable braking performance. Its working principle is: when the braking motor is energized, the braking motor gets 198V dc through 220V ac rectification, then the armature is electromagnetically attracted, so that the braking disc is in a rotatable state, and the braking motor rotates freely. When the braking motor loses power, the electromagnet loses power, and the armature is immediately supported by the spring, so that the braking disc and the motor rear end cover are pressed together and stop rotating.

Use condition editing

This series of motors can run continuously at rated power under the following conditions:

Altitude: no more than 1000 meters; Ambient air temperature varies with the seasons, but does not exceed +40℃.

Motor installation editor

1. The preparing work before installation, should check whether the packaging is intact before opening the motor, the phenomenon of presence of be affected with damp be affected with damp, after the open cover shall be careful to clear the dust and rust layer on the motor, carefully check the presence of deformation and damage in transit, have fasteners loose or fall off, the rotor rotation is flexible, nameplate data meets the requirement, using 500 VMQ table measuring high pressure resistance, insulation resistance shall be not less than 1 mq or dry processing should be made for winding but processing temperature not to exceed j-20 ℃.

2. Installation site and installation basis of the motor: the elevation of the installation site of the motor shall not exceed 100()m; General purpose motor installation site should be dry, clean, the motor should be well ventilated around, and other equipment should be left with a certain distance for inspection, monitoring and cleaning, the ambient temperature is below 40℃, and to prevent strong radiation; The installation foundation should be firm and firm with certain stiffness. The installation surface should be flat to ensure the balanced operation of the motor.

3. Wiring of the motor: the motor should be properly grounded. There are grounding devices in the lower right side of the junction box and the housing of the frame.

4. Connection between the motor and the mechanical load: the motor can be connected with the coupling, the front teeth shaft or belt and the load mechanical connection, the fan end of the biaxial extension motor is only allowed to use the coupling to drive. When coupling is used for connection, the center line of the motor shaft should coincide with the center line of the load machinery shaft, so as to prevent the motor from producing strong vibration, coupling shaft movement and abnormal sound during moving. The installation deviation of the device is: the allowable deviation of the 2-pole motor is 0.015mm, and that of the 4-pole, 6-pole and 8-pole motors is 0.04mm. For vertical mounted motors, shaft extension is only allowed to be connected with mechanical loads by coupling.

The dc disc brake of the YEJ series brake motor is mounted on the end cover of the non-axial extension end of the motor. When the brake motor is connected to the power supply, the brake also works at the same time. Due to the electromagnetic suction, the electromagnet attracts the armature and compresses the spring. When the power is cut off, the brake electromagnet loses its magnetic suction, and the spring pushes the bit to tighten the brake disc. Under the action of friction torque, the motor immediately stops corresponding to the YEJ braking motor of each type, and the corresponding YDEJ two-speed motor is also produced. The brake power is supplied by the rectifier in the motor junction box, 3 kw and below is ac220v-dc99v, 4 kw and above is ac380v-dc170v.

This series motor is in Y series (ip44) motor end cover and the fan after additional - between dc electromagnetic brake derived system is composed of the product, braking to power brake, this series of motor power level is the corresponding relationship between the size of the installation, installation size, type, insulation class, conditions of use, the work way, cooling method, rated voltage and rated frequency, and Y system (ip44) corresponding specification is the same, the protection grade of the motor is ip44, and brake the mechanical divided into ip23, the structure of the motor is shown in figure 1. The braking time characteristic of YEJ series motor is related to the connection of rectifier. The rectifier and the power supply are connected in two ways, the two friction braking time TBR is the same, but the release time is different.

YEJ, YED series three-phase braking motors and YDEJ, YDED series variable-speed three-phase braking motors are derived products consisting of a dc electromagnetic brake attached between the front cover and fan of Y series and YD series (IP44) motors. And has the international interchangeability. It can be used for export main machine. YDEJ, YDED series variable speed three-phase braking motors have a variety of variable speed, each speed has the same braking function as YEJ, yeyed series, can be used for a variety of mechanical equipment that need to have the pole speed and braking requirements.
