Electric motors are traditionally cooled using air. In very large machines, liquid cooling has already been used for some time. However even the lower power range (<50KW), liquid cooling can bring great benefits.
The lost heat from the motor is fed away by the coolant and as such, does not impact the immediate surroundings. In particular, this is a great advantage in:
• Precision machines
• Unfavourable installations (no air circulation)
• High ambient temperatures
• Climatised rooms
