Water cooled motors
Water-cooled motors are energy-efficient and environmentally friendly. Their advantage is reduced noise emission compared to surface-cooled three-phase motors of the same power and size.
Features
- Up to size 280 designed in cast iron with cast-in cooling tubes and from size 315 as double-walled welded steel construction
- Connection boxes, end shields, winding insulation, protection class and color scheme correspond to the series design
- the advantage of water cooling is a reduction in noise emission compared to surface-cooled three-phase motors of the same power and size
- the heat loss of the motors is dissipated without affecting the environment, and the cooling principle allows increased power and optimal vibration damping in a compact design of the motors.
The motors can be supplied in compliance with VO(EC) 640/2009 in the following versions:
- Without efficiency classification
- Standard Efficiency IE1
- High Efficiency IE2
- Premium Efficiency IE3
- Super Premium Efficiency IE4
Transponder optional, RFID system iID®2000 (13.56 MHz based on ISO 15693)
