Usual Tests done in Stator
1. Direction of Rotation
2. Winding Resistance
3. High voltage Test
4. Surge test or Q-factor test
1. Direction of Rotation
2. Winding Resistance
3. High voltage Test
4. Surge test or Q-factor test
The need of each test on stator is stated below-
High voltage test: The poor working on motor coil during the
production process makes the insulation distance shorter than standard and cause
the bad performance on dielectric withstand voltage between line to line.
Surge Test: If during motor winding process the copper/aluminium
insulation damages or scratch forms then it cause the bad performance on
dielectric withstand voltage between line to line. The quality is determined by
this process.
DC Resistance Test: To test if the resistance of coil is
normal and balanced
Direction of Rotation Test: To test if direction of rotation
of electro magnetic induction is in specific direction.
