WEG, manufacturer of motor and drive technology, has recently launched the new K1W series of water-cooled motors. The newly developed K1W motors are available up to energy efficiency class IE3 with rated power up to 700 kW 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, Antriebstechnik KATT Hessen, commonly known as 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,” said Uwe Guthardt, Managing Director of AKH. “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. 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.”

According to WEG, the 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, WEG said, is between 200 and 355 mm. The motor casing and bearing shells of the standard version are made from steel.

The electrical options include optimisation for variable-speed-drive operation as well as special voltages and frequencies, WEG said. The mechanical options of the K1W motors, WEG added, include water-cooled shafts, electrically isolated bearings, automatic lubrication, and foot or flange mounting.
