New water cooled motor offers extremely high efficiency and multiple application options

WEG has launched a new K1W series of water-cooled motors. These newly developed motors are available up to energy efficiency class IE3 with rated power up to 700kW and compact dimensions. They are suitable for a broad spectrum of applications, including mixers, extruders, injection moulding machines, printing presses, paper machines and wire drawing machines. The new series of motors was developed by WEG’s German subsidiary AKH. “The K1W series is a completely new line of water-cooled motors which are cost effective and meet the needs of a large number of applications thanks to numerous options. Among other things, they are a good choice when a lot of power is needed in a small space and the lowest possible noise level is desired”, says Uwe Guthardt, managing director of AKH. “The K1W series is ideal in situations where an external fan is not possible due to a high dust burden in the air or the motor heat cannot be dissipated directly to the ambient, for example in an operating environment that is already at an elevated temperature.” This new series of motors is built to the specifications of vibration level A, protection class IP55 and insulation class F as standard. The shaft height of the available motors is between 200mm and 355mm. The motor casing and bearing shells of the standard version are made from steel.
