Like in many other situations in life, the right level of cool can mean the difference between keeping things running smoothly and suffering a heat-induced breakdown.
Like in many other situations in life, the right level of cool can mean the difference between keeping things running smoothly and suffering a heat-induced breakdown.
When an electric motor is in operation, the rotor and stator losses generate heat which must be managed through an appropriate cooling method.
Efficient cooling – or the lack thereof – has a significant impact on the lifetime of your motor. This is especially the case for the bearings and the insulation system, which are the components most vulnerable to overheating. In addition, long-term overheating can cause metal fatigue.
This basic rule of thumb illustrates the relationship between heat and lifetime:
In addition to ensuring the health of the motor, maintaining optimal temperature levels are important to avoid efficiency reduction in general.
In short, ensuring proper heat management results in a more reliable and robust motor with a longer lifetime. And with an effective cooling system, it is often possible to use a smaller motor, which carries significant size-, weight- and cost reductions.
There are many cooling options available for electric motors. The optimal choice depends on your application, where the motor is mounted, the operating environment and several other factors. In this guide, we give you what you need to know to make an informed choice.
