Due to the electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, the brake disc is disconnected from the armature and the end cover, and the motor runs. The brake electromagnet loses the electromagnetic attraction force, the spring force pushes the armature to press the brake disc, and under the action of the friction torque, the motor immediately stops rotating. The excitation voltage of the electromagnetic brake is 205 VDC, and the rectifier power is 220 VAC.

The brake motor is a fully enclosed self-fan-cooled squirrel-cage three-phase asynchronous motor with an additional disc-type DC brake. It consists of a DC disc electromagnetic brake motor attached between the rear end cover of the Y series motor and the fan. It is a derivative of the Y series.
Features edit
It has the advantages of rapid braking, simple structure, high reliability and strong versatility. In addition, the brake motor has a manual release mechanism (the manual release mechanism is not designed for 60-90)
Application editor
Brake motors are widely used in various mechanical equipment and transmission devices that require quick stop and accurate positioning. The brake motor meets the JB / T6456-1992 standard. This series of brake motors are widely used in metal processing machine tools, packaging machinery, woodworking machinery, food machinery, chemical machinery, textile machinery, construction machinery, and gear reducers.
How it works
The DC disc brake for braking the motor is installed on the end cover of the non-shaft extension 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 effect of electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, the brake disc is disengaged from the armature end cover, and the brake motor starts to run. When the power is cut off, the brake motor electromagnet loses its magnetic attraction, the spring pushes the armature to press the brake disc, and under the action of friction torque, the brake motor immediately stops running; at the same time, the corresponding YDEJ two-speed (multi-speed, far-pole) Than) motor. The brake motor power is supplied by the rectifier in the motor junction box, AC220V-DC99V for 3 kW and below, AC380V-DC170V for 4 kW and above (in special cases, it can also be designed according to the manufacturer's requirements such as (DC24V)) → YEJ series electromagnetic system Moving the motor can achieve rapid braking after the motor loses power. Fast braking time: YEJ2-63-90 motor is less than 0.15 seconds, 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 user requirements. This series of motors have low noise and reliable braking performance. The working principle is that when the brake motor is energized, the brake motor obtains 198V DC through 220V AC rectification. At this time, the armature is electromagnetically attracted, so that the brake disc is in a rotatable state, but the brake motor is free to rotate. When the brake motor loses power, the electromagnet loses power, and the armature is immediately supported by the spring, so that the brake disc and the motor rear cover are pressed together to stop rotation.

Motor installation edit
1. Preparation before installation: Before unpacking the motor, check whether the packaging is complete and undamaged, and whether there is moisture. After opening the cover, carefully remove the dust and rust layer on the motor, and carefully check for deformation and damage during transportation. Whether the fastener is loose or falling off, whether the rotor is flexible, whether the nameplate data meets the requirements, and the high-voltage resistance is measured with a 500VMQ meter. The insulation resistance should not be lower than 1MQ, otherwise the winding should be dried, but the processing temperature should not exceed J20 ℃.
2. The installation site and installation foundation of the motor: The altitude of the installation site of the motor should not exceed 100 () m; the installation site of the general-purpose motor should be dry and clean, and the surrounding area of ​​the motor should be well ventilated, and some other equipment should be left The interval should be convenient for inspection, monitoring and cleaning. The ambient temperature should be below 40 ℃, and strong radiation should be prevented. The installation foundation should be firm and strong with a certain degree of rigidity. 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 of the terminal box and the housing of the base. If necessary, the motor feet or flange fastening bolts can be used to ground to ensure the safe operation of the motor.
4. The connection between the motor and the mechanical load: The motor can use a coupling, and the spur shaft or belt is mechanically connected to the load. The fan end of the dual-shaft motor can only be driven by a coupling. When using a coupling, the centerline of the motor shaft and the centerline of the load machine must overlap to prevent the motor from generating strong vibrations, coupling movements and abnormal sounds during movement. The installation deviation of the device is: the allowable deviation of the 2-pole motor is 0.015mm, and the deviation of the 4, 6, and 8-pole motors is 0.04mm. For vertical-mounted motors, shaft extensions are only allowed to be coupled with mechanical loads.

Braking motor working principle:

 

When the braking motor is energized, the braking motor obtains 198V dc through 220V ac rectification. At this time, the armature is magnetically attracted to make the braking disc rotatable, but 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.

 

Working principle of brake motor:

 

There is an electromagnetic holding brake at the end of the motor. When the motor is powered on, the electromagnetic holding brake is also powered on and closed. Then the electromagnetic holding brake does not brake the motor.

ABB brake motors are based on standard motors developed for braking applications, such as three-phase induction motors with standard sizes and rated output power. The electromagnetic disc brake passes dc current or three-phase ac current through the rectifier in the motor junction box.

Motor braking is to stop the motor in the power outage after the inertia operation.

There are two methods of motor braking:

1, mechanical braking: after cutting off the power supply, the use of mechanical devices to make the motor quickly stop the method known as mechanical braking. There are two kinds of mechanical braking devices which are electromagnetic holding brake and electromagnetic clutch.

2. Electric braking: after the motor is cut off from the power supply, it produces an electromagnetic torque (braking torque) opposite to the actual rotation direction of the motor, and the method of forcing the motor to stop quickly is called electric braking. The commonly used electric braking methods include reverse connection braking and energy consumption braking.
