YEJA Series AC Electromagnetic Brake Three Phase Motor Working Principle:

When electrified, the electromagnet produces a strong electromagnetic force to suck the armature plate to compress the brake spring, so that the armature plate can be separated from the pressure on the brake disc, and the motor can rotate flexibly. When power loss occurs, the armature plate is pressurized by the brake spring pressure to tighten the brake disc and generate a strong friction braking moment, so that the rotating motor brakes rapidly and achieves accurate positioning.

YEJA Series AC Electromagnetic Brake Three Phase Asynchronous Motor Features:

1. The protection level of this series of products reaches IP55.

2. The cooling mode of the motor is IC411 (self-fan cooling).

3. The AC brake has been carefully designed. In addition to the charged part sealed in the epoxy resin shell, the brake is installed in a fully sealed structural component when it is assembled with the motor, which can effectively prevent cotton yarn, paper scraps, dust, grease, iron scraps, powder, and other impurities from entering the brake, thus prolonging its service life.

4. AC brake has the advantages of fast starting response, short braking time, safe and reliable braking moment adjustable, etc.

5. With a flexible manual release device, the self-locking or temporary wrench can be freely chosen;

6. AC brake and motor use the same power supply voltage, without AC-DC conversion rectifier, avoid AC-DC conversion, easy to use;

7. Motor insulation grade is B and F, and brake insulation grade is F.

8. Use two-position junction boxes, i.e. separate junction boards for motors and brakes respectively.

9. Installation size and power level of the motor fully conform to JB/T6456 industry standard and IEC-72 international standard.

10, 63-71 are aluminum-shell motors, 80-160 are aluminum-shell or cast-iron-shell motors, and 180 are cast-iron-shell motors.

YEJA Series AC Electromagnetic Brake Three Phase Asynchronous Motor Common Failures and Troubleshooting:

NO.	Fault phenomenon	Examination site and method	Solutions
1	Brakes do not absorb severe vibrations and squeaks	(1) As shown in Figure 1, check whether nut 5 is loose or not. (2) Measure whether the air gap (S) exceeds the maximum working air gap value; (3) Measure the resistance of three-phase winding with a multimeter. Is it basically average? Is there a break? (4) Check whether the AC three-phase power supply is out of phase with the SOOV AC voltage of the multimeter; (5) excessive braking moment exceeding rated value; (6) Check whether foreign bodies are stuck on the surface of iron absorption or whether dry grease deposits cause unevenness on the surface; (7) The surface of iron absorption is uneven after long-term use.	(1) Tighten nut 5; (2) If the air gap (S) is too large, it will be adjusted to the Initial working air gap. (3) To repair or replace the magnetic rollers with broken wires; (4) Eliminate problems found; (6) Adjusting the compression length of the brake spring to control the braking moment; (6) Removing foreign bodies and grease scale; (7) Leveling by lathe or surface grinder;
2	Brake fail ure and brake fail ure	(1) Friction disc wear. The working air gap increas- es and the torque decreases. (2) Friction disc damage; (moment inertia Is too large to exceed braking	(1) Re-adjusting air gap（δ）； (2) Replacing new friction discs; (3) Re-selection of motor models
3	Motor heating	(1) Overload. Over the specified current of name- plate. (2) Using a frequency converter power supply, the use time in low frequency band is too long; (3) Whether there are cotton wool, yam and paper on the air Inlet and blade of the motor to block up the cooling air source. (4) Check whether the power supply and motor are out of phase.	(1) Reduce the load, control the rated load, of reconsider the selection of motor. (2) External additional fan; (3) Clean up cotton floss and other debris in the ah Inlet of the motor and on the wind blade; (4) Repair.
4	When released manually the rotat ing shaft does not move.	(1) The friction disc is adhered to by oil (from the gearbox or elsewhere). (2) The brake is not used for a long time, and the plane friction disc of the motor end cover is rusty,	(1) Remove the friction disc and wipe it dry before assembling. (2) After disassembly, the rust spots can be removed and reassembled, which will work normally.
