1、the power of motor is Y-connection at or below 55 kW, and the power above 55 kW is delta-connection；
2、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, select the thickness of the feeler gauge according to the specified initial working air gap value, loosen the nut 11, loosen the fixing screw 13 slightly, loosen the support adjustment screw 12, and put the feeler gauge into the quilt In the air gap (δ) next to the loosened screw, slowly screw in the fixing screw 13 to tighten the feeler gauge, and then press the support adjusting screw 12 against the end cover plane, and pull out the feeler gauge. There are three sets of fixing screws 13, adjust the air gap values on the sides of the three sets of screws to the initial working air gap value according to the above method, and the air gap values at the three places are uniform, and then tighten the nut 11.

YPEJ160 and above adjustment method: select the thickness of the feeler gauge according to the specified initial working air gap value, loosen the fixing screw 13, loosen the support adjusting screw sleeve 9, put the feeler gauge into the air gap next to the fixing screw 13, and slowly rotate Insert the fixing screw 13, press the feeler gauge, and then press the support adjusting screw sleeve 9 against the plane of the end cover (1), and pull out the feeler gauge. There are six sets of fixing screws 13. According to the above method, adjust the air gaps on the sides of the three sets of screws equally divided into 120° to the initial working air gap value, and the air gap values of the three places are uniform, and then adjust the air next to the other three sets of fixing screws. Clearance (δ), and tighten the fixing screw 13 and the support adjusting screw sleeve 9. The adjusted air gap should be checked once with a feeler gauge to prevent uneven air gap. If there is no feeler gauge, the air gap adjustment can be replaced by iron sheets of similar thickness.
