When a motor-driven machine starts to fail, one of the earliest signs is an increase in power draw by that motor – typically before you can hear a problem or it overheats. For example, a deteriorating bearing or a short in the windings or a plugged downstream filter, can result in significant increases in power draw.
If the motor normally draws between 20kW and 40kW an hour, alerts can be set at 15kW and 45kW - with or without a time delay. So, if the motor exceeds 45kW for a period of X minutes, an alert will be sent.
Here are common problems that can occur with motor-driven systems…
- Torque Overload
- Windings insulation failure
- Rotor/Stator/bearing failures
- Phase imbalance
- Capacitor failure
- Clogged downstream filters
- Broken or slipping drive belt
- Loose or sheared shaft coupling
- Open pump discharge
- Restricted pump intake
- Clogged intake filters or screens
In addition to motor-driven machinery, SW can monitor heating equipment too – e.g. heating elements in furnaces. The graph below shows a furnace remaining at maximum temperature for about 3 times its normal cycle.
