The YPEJU series variable frequency speed regulation AC brake three-phase asynchronous motor is composed of YP series variable frequency speed regulation three-phase asynchronous motor, three-phase AC brake, and cooling fan.
The high-frequency pulses and high-order harmonics generated by the variable frequency power supply have a significant impact on the windings of the motor and brake, so special measures are taken in the insulation structure of the motor and brake. The brake is an advanced AC brake that is directly powered by a three-phase power supply instead of a DC power supply, without the need for rectifier electronic components, greatly improving the reliability of operation.
The communication brake has the advantages of fast starting response, short braking time, accurate positioning, and long service life.

The YPEJU series brake motors can be widely used in industries such as light industry, textile, mechanical transmission, electroplating production lines, etc. Any equipment that requires speed regulation, fast braking, and accurate positioning is suitable for using the YPEJU series brake motors.

The installation size and power level of the YPEJU series brake motor are the same as those of the Y series motor, but the overall length of the appearance has increased.
The protection level of this series of products is IP44 and IP55 for motors, and IP23 for AC brakes; Insulation level: The motor is rated B and F, and the AC brake is rated F.  

Usage conditions:
1. Altitude not exceeding 1000m;
2. The maximum ambient temperature shall not exceed 40 ℃, and the minimum shall be -15 ℃;
3. Relative humidity ≤ 95%;
4. Power supply voltage: three-phase 380V (220) 50Hz;
5. Working mode: S1 (continuous work system);
6. Speed regulation range: 5Hz~50Hz constant torque speed regulation;
50Hz~100Hz constant power speed regulation;
Inspection and adjustment of gaps:
The distance between the armature plate and the electromagnet is called the gap (δ). The normal working clearance (δ) is controlled within 0.2-0.3mm, with a maximum of 0.5mm. The motor is adjusted within the normal working clearance range when it leaves the factory. After running for a period of time, the clearance value increases due to friction plate wear. If it exceeds the maximum clearance, it will affect the normal suction and braking of the AC brake and must be adjusted.
Adjustment method: Prepare a set of thick and thin feeler gauges, select 0.25mm pieces, first measure at the gap (δ) position (three screw orientations) shown in Figure 1. If it has exceeded, loosen nut 5, place the 0.25mm feeler gauge into the gap (δ) of the loosened screw, slowly screw in safety nut 7, tighten the feeler gauge, then tighten nut 5 outward and pull out the feeler gauge. Adjust the gap between the second and third screws using the same method, and then tighten nut 5 again. Nut 5 must be tightened and checked regularly to ensure it is not loose.
If there is no regular feeler gauge, a similar thickness of iron sheet can be used as a substitute. The safety nut 7 moves forward by about 0.15mm every 60 ° rotation (hexagonal nut divided into six equal parts). The three points of gap adjustment must be uniform, otherwise it will affect the brake suction and braking, and in severe cases, it may burn out the coil.
Adjustment of torque:
When the motor leaves the factory, the torque has been adjusted to the standard value. After using the motor for a period of time, due to the wear of the friction plate, the brake spring is slightly relaxed, and the braking torque relatively decreases slightly. If the use does not have a significant impact, it can be left stationary. If you feel a decrease in torque and need to increase the braking torque, you can evenly rotate the three safety nuts 4 forward by about 180 ° (about half a turn), at most one turn, not too much. Due to the large braking torque, it may cause difficulty in engagement or make unpleasant squeaking electromagnetic sounds, and in severe cases, it may burn out the coil. If the braking torque needs to be reduced, loosen the safety nut 4 backwards by 180 ° (half a turn), at most one turn, otherwise the torque will be too small. Regardless of whether the torque is adjusted small or large, the clearance needs to be readjusted.





Installation and external dimensions:



*R is the distance from the mating surface of the flange cover to the shoulder of the shaft extension.

Wiring method:

Note: The power supply voltage and connection method (Δ or Y) of the motor and AC brake are completely consistent. Please wire them according to the connection method indicated on the nameplate. The electric motor and brake must be powered on simultaneously.
