Motor Temperature Monitoring

Motor Temperature Monitoring Image


To ensure proper facilities or process operation, it is important to monitor the operating performance of important components such as motors. It is possible to predict maintenance requirements or failing motors by monitoring the temperature of either the motor case or the bearings. The heat generated by failing motors and bearings can be detected before the devices shut down, minimizing facility downtime and machine damage.

In some situations, constant monitoring of a single motor may not be required. In this case, a battery-powered FlexPower Node allows the monitoring equipment to be moved between multiple motors quickly.


FlexPower Nodes equipped with thermocouple or RTD sensors were mounted near the monitored motors. The sensor data is sent to a Gateway installed in a central control location. The temperature set point can be established to meet the applications requirements and then provide a discrete output from the Gateway. When predetermined temperature levels are detected, the red light of a stack light connected to a Gateway lights up, alerting personnel that maintenance is required.

The Gateway has 6 discrete inputs and 6 discrete outputs to allow for multiple Thermocouple Nodes to interface with a single stack light indicator.

Each of the six outputs of the Gateway is tied to a separate Node that monitors motors and provides an indication of failing components. Other elements important to motor operations, such as current draw or vibration, can be monitored using the appropriate sensors and Banner SureCross Wireless products.

Monitoring motors for proper operation with a permanently mounted or temporarily deployed wireless solution allows operators to predict potential failures. The ability to monitor motors in inconvenient locations previously not monitored allows for a more comprehensive review of equipment.
