Global presenceSEW-EURODRIVE is driving the world with innovative drive solutions for all branches andevery application. Products and systems from SEW-EURODRIVE are used in a multitude ofapplications worldwide. Be it in the automotive, building materials, food and beverage ormetal-processing industry, the decision to use drive technology "made by SEW-EURODRIVE" stands for reliability and quality.

We currently have 15 manufacturing plants, 79 assembly plants in 48 countries, and acomprehensive range of services that represents our commitment to outstanding quality.

Complete solutionsThe SEW-EURODRIVE modular concept offers millions of combinations. This wideselection enables you to choose the correct drive for all applications, based upon your re-quired speed, torque, available space, and ambient conditions. We offer many gradual sizesof gear units so there is always a unit that closely matches your torque requirement to pro-vide the best economic solution and to prevent unnecessary oversizing.

Gearmotors are powered by MOVITRAC® or MOVIDRIVE® frequency inverters orMOVIAXIS® multi-axis servo inverters, providing a single-source solution for all of yourneeds. Whether its electronics or mechanical systems, SEW-EURODRIVE is responsiblefor the complete development, production and assembly of all products in order to providethe utmost in flexibility.

Products of the servo drive system provide precision and dynamics, including low backlashservo gear units, compact servomotors, and MOVIAXIS® multi-axis servo inverters. Fromsingle-axis or multi-axis applications all the way to synchronized processes, servo drivesystems by SEW-EURODRIVE offer a flexible and customized implementation of yourapplication.

For economical decentralized installations, SEW-EURODRIVE offers components such asMOVIMOT®, the gearmotor with integrated frequency inverter or MOVI-SWITCH®, thegearmotor with integrated switching and protection. Our hybrid cables have been designedspecifically to ensure cost-effective solutions, independent of the system size or system type.

The latest developments from SEW-EURODRIVE include: MOVITRANS® - contactlessenergy transfer, MOVIPRO® - decentralized drive control, and MOVIFIT®- decentralizedintelligence.

Power, quality, and sturdy design define the industrial gear units available from SEW-EURODRIVE. With high torque capacity and a modular concept, the industrial gear unitsonce again provide optimum adaptation of a standard product for a wide range ofdemanding applications.
