1、the motor part, when it leaves the factory at or below 3kW, is Y-connection, and the rest 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.

The motor is connected by Y and the brake is connected by DC99V as follows:

The motor is connected by delta and the brake is connected by DC170V as follows:

The motor is connected by Y and the brake is connected by DC170V 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 7 and electromagnet 12 is called air gap (delta). Normal working air gap (delta) does not exceed the prescribed maximum air gap value. The motor is adjusted at the beginning when it leaves the factory.Within the working air gap range, after running for a period of time, the air gap value will increase due to friction wear, which will affect the normal suction and braking effect of the brake. Therefore, after the motor is used for a period of time, it  must press Maximum air gap value, select plug size, check the size of air gap. When inspecting, the size of the plug ruler can be directly inserted into the air gap (delta). If it is inserted, it means that the air gap is too large and must be entered.Line adjustment.

3. Air Gap Adjustment

The gauge thickness is selected according to the specified initial working air gap value. As shown in Fig. 1, loosen the inner hexagonal screw 16, and screw the support adjusting screw sleeve 1 to the electromagnet direction for 1-2 mm to facilitate air  gap adjustment. Place the plug ruler in the air gap (delta) next to the support adjusting bolt, slowly screw in the inner hexagonal screw 16, press the plug ruler. Fig. 1 then tighten the top cover 8 plane of the support adjusting screw sleeve, and pull out the plug ruler. There are three groups of internal hexagonal screw 16 for DZK04-75 fixation. 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 in the three places must be uniform. Finally, the internal hexagonal screw 16 must be tightened. There are four groups of internal hexagonal screw 16 for DZK150 fixation. The debugging method is the same as above. Generally, diagonal screw should be adjusted first. After adjustment, the air gap should be checked once with a plug ruler to prevent the unevenness of the air gap. If there is no standard plug gauge for air gap adjustment, it can be replaced by similar thick and thin iron sheet.

4. Torque Regulation

When the braking moment does not reach the rated braking moment in the normal working air gap, three insurance nuts 4 (six above seat number 132) can be uniformly screwed forward and compressed.Dynamic spring 3, can increase the braking moment, but not too much, as long as it reaches the rated braking moment on the nameplate, because the spring pressure is too large, it will cause difficulty in attracting, or give out ugly.Squeezing electromagnetic sound, serious will burn the coil.
