Product Brief

YPEJ series frequency conversion speed regulation electromagnetic brake three-phase asynchronous motor is composed of YP series frequency conversion speed regulation three-phase asynchronous motor, DZM series DC electromagnetic brake and cooling fan. It is a motor suitable for frequency conversion speed regulation.

 

Scope of use

This series of motors are suitable for light industry, textile, electroplating pipeline and other industries requiring mechanical transmission, to achieve speed regulation, accurate positioning, reciprocating operation and other actions.

 

Working principle

When electrified, the electromagnet produces a strong electromagnetic force to suck the armature plate to compress the brake spring. The two dual surfaces of the friction disc are separated from the pressure of the armature plate and the plane of the back cover of the motor, and the motor can rotate flexibly. When power is lost, the armature plate is pressurized by the pressure of the brake spring to tighten the friction disc and generate strong friction braking moment, so that the rotating motor brakes rapidly and achieves accurate positioning.

 

Product characteristics

1. The overall protection level of the motor is IP44.

2. Motor cooling mode IC416;

3. The release device is external, and the manual release is flexible and convenient.

4. The insulation grade is F.

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

6. 71 motor case is aluminium alloy, 80-160 motor case is aluminium alloy or cast iron, 180 and above motor case is cast iron.

 

Conditions of use

1. Rated voltage: The standard product is AC380V 50Hz;

2. Working mode: S1 (continuous working system);

3. The altitude should not exceed 1000mm.

4. Environmental temperature: - 15 ~40 C;

5. When the monthly mean minimum temperature is not higher than 25 C, the wettest monthly average maximum relative humidity is 95%.

6. Speed regulation range: 5Hz-50Hz is constant torque speed regulation, 50Hz-100Hz is constant speed regulation.

Firstly, the power of motor is Y-connection at or below 55 kW, and the power above 55 kW is delta-connection.

Secondly, the brake part, the motor with seat number 100 and below is DC99V, and the motor with seat number 112 and above is DC170V.

3. Fast brake connection method is as follows:

I. Air Gap Value of Brakes in Electric Machines of Various Specifications in this Series (Delta)

 

2. Inspection of air gap

As shown in Figure 1, the distance between armature plate 5 and electromagnet 6 is called air gap (delta). Normal working air gap (delta) does

not exceed the specified maximum working air gap value. All motors are adjusted at the beginning when they leave the factory.

Within the initial working air gap range, after a period of operation, the air gap value will increase due to friction wear, which will affect the

normal suction and braking effect of the brake. Therefore, it is necessary to use the motor for a period of time.

According to the maximum working air gap value, the size of plug gauge is selected and the size of air gap (delta) is checked. When checking,

the size of the plug ruler can be selected and inserted into the air gap (delta). If the plug is inserted, the air gap is too large.Adjustments must

be made.

 

3. Air Gap Adjustment

YPEJ71-YPEJ132 Adjustment Method: As shown in Figure 1, the thickness of plug ruler is selected according to the specified initial working air

gap value, the nut 11 is loosened, the fixed screw 13 is loosened slightly, and the adjusting screw of expenditure support is loosened.12. Place

the plug ruler in the air gap (delta) next to the loosened screw, slowly screw in the fixed screw 13, press the plug ruler, then tighten the top

cover plane of the supporting adjustment screw 12, and pull out the plug ruler. Fixed screw

There are three groups of screw 13. The air gap values on the edges of the three groups of screw must be adjusted to the initial working air gap

values according to the above methods. The air gap values at three places must be uniform and the nut 11 must be tightened finally.

YPEJ160 and above adjustment methods: according to the specified initial working air gap value, select the thickness of plug ruler, loosen the

fixed screw 13, loosen the expenditure support adjustment screw 9, and put the plug ruler into the air gap beside the fixed screw 13.

In the middle, slowly screw in the fixed screw 13, press the plug ruler, then tighten the top cover (1) plane of the support adjustment screw

sleeve 9, and pull out the plug ruler. Fixed screw 13 has six groups and must be equally divided into 120 degrees according to the above

method.

The air gap on the edge of the three sets of screw is adjusted to the initial working air gap value. The air gap value at the three places must be

uniform. Then the air gap (delta) next to the other three sets of fixed screw is adjusted, and the fixed screw 13 and the support adjustment are

tightened.

Throttle sleeve 9. The adjusted air gap should be checked once with a plug ruler to prevent uneven air gap. If there is no plug ruler, air gap 

adjustment can be replaced by similar thickness of iron sheet.
