  2. Operating temperature - Wikipedia

    en.wikipedia.org/wiki/Operating_temperature

    An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...

  5. Condition monitoring - Wikipedia

    en.wikipedia.org/wiki/Condition_monitoring

    Condition monitoring. Condition monitoring (colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance.

  8. Cogging torque - Wikipedia

    en.wikipedia.org/wiki/Cogging_torque

    Cogging torque. Cogging torque of electrical motors is the torque due to the interaction between the permanent magnets of the rotor and the stator slots of a permanent magnet machine. It is also known as detent or no-current torque. This torque is position dependent and its periodicity per revolution depends on the number of magnetic poles and ...
