🔍 Recommended Diagnostic Tests for SGMGH Motors:
✔ Megaohm Test (Insulation Resistance Check) – Using a megohmmeter is crucial for verifying the motor's insulation and detecting ground faults. Important: If testing while the motor is installed in the machine, disconnect the cables from the drive before using the megohmmeter to prevent drive damage.
✔ Phase-to-Phase Resistance Check – This test ensures motor winding integrity. While standard multimeters can be used, milliohmmeters provide more accurate readings. Resistance values should be low, nearly shorted, and within 10% of each other.
✔ Manual Shaft Rotation Test – If the motor is out of the machine, manually rotating the shaft can help diagnose issues in Chicago. Note: If the motor has a brake, it must be disengaged before testing shaft movement.
