www.weg.net Water Cooled Motors WEG Water Cooled motors were developed to match the increasing market demands for compact design motors with low noise level and high output power ratio per frame size. These motors meet the IE2 efciency levels dened by IEC 60034-30:2008 Standard, thus ensuring lower energy consumption and consequently reducing their operating costs. Construction characteristics The motor cooling is ensured by a jacket where the water ows uniformly between the stator core and motor frame. This cooling system is a very efcient method of transferring heat away from the motor,...

www.weg.net These motor frames are made of FC-200 cast iron, without requiring additional seals between the components which reduces inspection interventions. Other parts of the Water Cooled motors are fully interchangeable with the W21 and W22 lines which ensures major exibility and reliability to the whole set. Features and benets Features Benets Efciency levels in accordance with EC 60034-30:2008 Standard Lower energy consumption and reduced operating cost Water cooled Ensures more heat dissipation and allows higher output per frame size External fan not required Reduced noise level...

www.weg.net Low noise level The fan is one of the main acoustic noise sources in rotating electric machines. As the Water Cooled motor does not require the application of a cooling fan, this reduces the noise level and ensures a noisless operation with high performance, low mechanical losses and consequent efciency increase. Wide speed range at constant torque Water Cooled motors do not have cooling efciency reduction as result of the speed decrease of self-ventilated motors when driven by VSD. The continuous water ow through the frame jacket allows the motor to provide constant torque from...

www.weg.net Output per frame Due to the improved heat dissipation of the Water Cooled motors, they can provide higher outputs in equivalent frame sizes when compared to self-ventilated motors. Therefore, Water Cooled motors ensure optimization of the installation space for their compact design which reduces the end size of the equipment where they will be installed. The table below shows the guiding ratio for the outputs per frame for 50 Hz motors based on a maximum water input temperature of 40 °C.
