Voith Drive™ –direct drive, direct advantage

Voith Drive™

small, compact, powerful

Impressive balance

Voith Drive is the integrated solutionfor an innovative drive that replacesthe traditional arrangement of car-dan shaft, gear unit, coupling andmotor. The motors are simplyslipped on at tender or drive sideand drive the rolls without backlashand without any intermediatemechanical components.The frame-mounted gear unit andall mechanical drive parts, there-fore, become superfluous.

Abundant power

The achieved torques are impres-sive. They are available even at lowrotational speeds and remain virtu-ally constant throughout the speedrange. Because of the low circum-ferential backlash, the motors arecharacterized by maximum controlquality.

Universally applicable

The advantages of Voith Drive areobvious. On all paper and spreaderrolls, in the dryer section, in thecalender as well as in the wind-upsection and the rope drives, thecompact design of Voith Driveallows easy integration into themachine.

Conventional drives for paper machines now have a problem,

because Voith Drive, an innovative drive for front and drive

side, for new machines and rebuilds, shows its superiority in

all parameters. And that means hard cash for you.

convincing all along the line

Less energy

With Voith Drive, the omission ofmechanical drive parts such asgearwheels, cardan shafts andcouplings increases the over-allefficiency. That significantly reducesthe complete energy consumptionof your paper machine.

Less noise

The compact, wear-free Voith Driveperceptibly and significantly lowersthe noise level in the machine room.This takes the burden off your staff.This quiet, backlash-free powertransmission without mechanicaldrive components additionallyensures better runnability of yourpaper machine.

Mastering extreme conditions

The extreme ambient temperaturesand the high air humidity prevailingin the dryer hood place extraordi-nary demands on the engineeringaspects. Voith Drive is optimallydesigned for these:� Magnetic material� High-temperature bearing grease� Coating of rotor and stator� Seals at the terminal boxes� Motor with special coat of paint� Transmitter systems for high

temperatures

You want to make your paper production process more efficient?

You are interested in minimizing your energy consumption and the

high operating costs for storage and maintenance? Reduced noise

pollution for your staff is a prime concern of yours? Then decide in

favor of Voith Drive.

Lower operating costs

The operating costs go down, asVoith Drive drastically reducesmaintenance expense and storagecosts. You require fewer spare parts because wear-intensive gearwheels are a thing of the past.

No oil

Through the omission of all gearwheels costly central oil lubricationis no longer required. The oil con-sumption is thereby considerablyreduced. There are no longer any oil leakages , i.e. oil-contaminatedframing parts belong to the past.This improves the environmentalbalance of your production line.

Bringing up to the right

temperature with water

The motors of Voith Drive arecooled via a closed water cycle with upstream dirt filter and deliverypump. This leads to high powerdensities. Even continuous opera-tion at crawl speeds is made possi-ble without any problems. All pipingis made from stainless steel.

Perfect Fit

If you decide on Voith Drive for a rebuild, this is the “Perfect Fit”solution. The compact design allowsimmediate integration into themachine, both on the drive side and on the tender side. Voith Drivemakes installation more flexible,shortens the rebuild times andlowers capital costs.

successful in commercial operation

The Voith Drive drive concept hasbeen running successfully since theyear 2000 in many paper machinesall over the world. Voith Drive raisesthe economic efficiency of yourproduction line, minimizes operatingcosts and improves your staff’sworking conditions thanks to thelower noise level of the drives.Voith Drive is the modern drivesystem for the paper industry.

LEIPA-Schwedt PM 4

PM 4 is the most modern LWCpaper machine in the world, with awire width of 8,900 mm and a maxi-mum drive speed of 2,000 m/min.

The latest technology requires aninnovative drive concept: 30 VoithDrives of the most varied capacitiesensure the necessary dynamics onPM 4 and thereby increase the totalefficiency of this demanding system.

Velsen PM 2

Voith received an order from Papier-fabrik Crown van Gelder for therebuild of PM 2 in the shortest timepossible. The goals were:� Higher production speed� Elimination of the defective gear

wheels� Elimination of oil leakages in the

frame-mounted gear units.

With Voith Drive these demands were met on schedule. In addition,the energy costs were significantlycut and noise pollution for the staffwas greatly reduced.

Voith Drive has excellent references. The drive without

additional gear wheels, cardan shafts and couplings is

the drive concept of the future and has proven success-

ful in applications worldwide.
