PM Motor Step-out (Permanent Magnet Motor Pulls Out of Synchronism)

What does SOUt mean?

This fault occurs in permanent magnet motors when the motor pulls out of synchronism, often due to a jammed motor, output phase loss, or sudden impact loads, leading to uncontrolled rotation.

• The permanent magnet motor is jammed.
• Output phase loss to the motor.
• Sudden impact load on the motor.

Click steps to track your progress.

1. 1

   Check the mechanical load and correct any jammed conditions.

2. 2

   Check the condition of the motor windings and load wiring for integrity.
