High-voltage motor coil temperature
Thread Content
After the maintenance of the primary fan motor for the 500Kw/1Kv boiler, it was tested by running it idle for 4 hours. There are two temperature monitoring points for the coils: one read 51°C and the other 54°C. Is this within the normal range? (Environmental temperature: 32°C) It was serviced for the second time. During the previous test run with it running idle, the temperature reached almost 70°C, which is similar to the temperature when it is operating under load; therefore, it was taken back for further servicing. Thank you!
It’s hard to say; we need to observe more； Additionally, if possible, you can swap the two measurement probes and take measurements to see what happens.
