Troubleshooting motor problems
Nagging problems with your motorized machinery? Can’t determine the root cause? Not surprising. Given the interrelated nature of power, motor and load in a motor/machine system, it can be difficult to determine how these interrelationships can impact motor performance. Preventive maintenance planning can help to accurately identify and correct the problem, you need to view all three basic elements of the motor/machine system: the power supplied to the motor, the motor itself, and the load (such as a pump, fan, or conveyor drive).
