Environment and contamination

Posted on by Matt Passannante

Environment conditions and contamination are a main cause of motor failure. Environmental conditions refer to a number of factors, including the ambient temperature at which the motor operates. Every motor has its own distinct recommended operating range. The operating range is determined by the viscosity of the bearings’ lubricant and the motor’s ability to withstand heat. If the ambient temperature is outside of the motor’s operating environment, contamination can result. Contamination happens when the motor is exposed to temperatures that are lower or higher than the ambient temperature. The lubricant, for instance, may freeze at colder temperatures.
