Motor temperature measurement point
Thread Content
The temperature sensing point for the motor stator is an embedded thermistor; if it fails, no temperature value will be displayed. Is it necessary to disassemble the coil in order to replace it?
The motor stator RTDs are usually provided in a one-main-one-redundant configuration; if both fail, the coils will have to be removed. The internal structure is not understood.
I just checked – if both are damaged, then they’re both broken; it’s not possible to remove the coils and replace the RTDs on site. If it must be replaced, it needs to be taken to the motor factory
It’s a big problem if both components inside the coil are damaged~~ The user unit simply can’t fix it~~ It needs to be sent back~~
