How do you cool an electric motor?

Electric motor cooling fans are used to reduce and regulate temperatures on electric motors. To determine how effective a motor cooling fan is, volume, static pressure, and altitude are all considered. In other words, how much air it moves and at what pressure. Other factors considered in calculating the effectiveness are the use of variable frequency drives (VFDs), trimming or machining the impeller, and the use of fan covers. When determining the effectiveness of an electric motor cooling fan a skilled Jenkins technician can help you through the process of choosing the right fan to cool your electric motor.
