Electromagnetic coil resistance:
1. Unless otherwise specified, the resistance value of the coil is 20℃;
2. The resistance should be within the tolerance range: 5% (when the standard resistance is less than 1000Q) or 7% (when the standard resistance is 21000Q).
Inspection rules for electromagnetic coils:
01. Classification of electromagnetic coil inspection The inspection of electromagnetic coil is divided into factory inspection and type inspection.
