Växellösa Hissmaskiner

Wittur provides high quality gearless machines for lift applications, setting the highest standard in the high rise segment and proposing smart solutions in the machine room-less and modernization market. Compared to traditional gearbox machines, gearless technology offers advantages like reduced noise and vibrations and increased suspension load. Gearless machines are environmentally friendly, reducing the energy consumption and eliminating the need for lubricating oil.

 

Servo gearless

Now available in ECO version Servogearless synchronous traction machines is ideal for use without a machine room, as small as servo, as powerful as a torque motor, smart and simple installation. Thanks to a electro-magnetic redesign the traction machines “servogearless” are available now in ECO version with lower current consumption. This current drain has been reduced for different applications by more then 20%. Smaller inverter sizes can be used in many cases.
