JB/T7085.3—1993
5.3 The slot insulation size and placement should meet the requirements of the drawings and meet the requirements of Article 26.1 of GB3883.1. 5.4 The model and wire gauge of the enameled wire should meet the requirements of the drawings. 5.5 The model and cross-section of the lead wire should meet the requirements of the drawings. 6 Winding preparation
Install the coil mold
Install the corresponding coil mold on the coil winding machine according to the coil specifications. 6.2 Check the equipment
Check whether the coil winding machine is running, the brake is normal, and the count is accurate. 6.3 Introduce the enameled wire
Introduce the enameled wire that meets the requirements of 5.1 and 5.4 into the clamping device, adjust the clamping force, and then pass it through the wire arrangement device. 6.4 Preset the count value
Preset the count value or adjust the hanging wheel according to the number of coil turns. 7 Windingbzxz.net
7.1 Put wax wire in the coil mold groove, introduce the enameled wire into the coil mold, wrap the wire end around the wire hook, start the motor to wind the wire, and automatically brake when the number of turns reaches the preset number.
7.2 After stopping, tie the coil tightly with wax wire and cut the wire according to the required wire end length. 7.3 Remove the coil mold, take out the coil to complete the winding work, and put the coil into the work station equipment. 7.4 Remove the paint film on the wire ends, wrap them with the lead wire core, and solder them, then put on the insulating sleeve. The lead wire length and placement direction should be in accordance with the drawing requirements.
7.5 Wrap them with wrapping materials in a folded manner. The wax wire should be removed during wrapping. 8
Quality inspection
Measure the wire girth and DC resistance.
