Abstract

An electric motor is equipped with an interface module, which is used to calculate the remaining service life of a bearing. The interface module can be integrated into the motor or can be fitted to the latter. The remaining service life of the bearing can be estimated from the signal of a rotary transducer and optionally a temperature sensor.
