Product Portfolio
  • Gearboxes and Geared motors

      • New WG20 Motors

      • WG20 is the first geared motor range to be completely developed in-house at WEG.

        It comprises helical, parallel shaft and helical bevel gear units with torques between 50 and 600 Nm. These two-stage units excel with their large ratio range, as well as being exceptionally efficient thanks to the sophisticated design. The light, yet robust, aluminium housing of the gear units in the WG20 range provide a highly versatile and reliable product, with a wide range of possible applications.

          • Helical geared motors C

          • The helical gear units come in five housing sizes for nominal torques from 50 to 600 Nm and are available in both foot and flange designs. While the two smaller gear units (C00 and C01) are able to perform to their full potential with just two stages, the larger C03 to C06 are available in both two and three-stage versions, for those applications in higher torque ranges.
          • Parallel shaft geared motors F

          • Thanks to their structural design, parallel shaft gear units are particularly suitable for conveyor technology applications. All four sizes can be fitted with either a hollow shaft, output shaft, mounting flange or shrink disc. The ratio range of gear unit sizes F04 and F05 can be extended by a third gear stage.
        • Geared motors

        • Top Quality Geared Motors.

          Watt Drive gearboxes and geared motors are the electro-mechanical key elements for low backlash, smoothly running and highly dynamic drive systems. Our high-performance gear units are built to withstand the toughest industrial applications. The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry. As a result our geared motors are often to be found as part of our customers own machines. The smooth running of Watt Drive gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.

          The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity enables smaller wheels to be used for the same torque, and smaller gears with exceptional power density also increase reliability. Watt Drive geared motors are consequently incredible space savers. Gearing manufactured with such micro-geometric precision allows the gearing play required for trouble free rolling contact to be substantially reduced and therefore the gear backlash to be minimized. Double chamber shaft seals developed by Watt Drive are used as standard in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.

          Watt Drive’s modular gear technology meets the requirements of advanced drive systems:
          • Excellent power density
          • Minimum backlash
          • Smooth running
          • Diverse mounting options
          • Maximum reliability
          • High variability
            • Helical geared motors

            • The Uniblock design - foot and flange execution in one case!

              UNIBLOCK® design for foot and flange mounting. Gear housing machined on all sides for universal application.
              Optimized gearing geometry here and in all the other models results in exceptional running smoothness. For special environmental conditions the gear unit can be fitted with two shaft seals.

              • High pressure ventilation valve
              • Oil level sensor
               
            • System adapter

            • The Watt system adapter enables all motors commonly found on the market to be built on the complete MAS® gear system.

              The drive motors are added on by using the adapter, without having to open the gears. The motors do not need to be oil-tight.

              The system adapter enables the following to be added:
              • Servo motors, with or without key
              • Nema motors (standard measurement Type C flange fixture)
              • IEC motors (model type B5 according to DIN 42677)

              • Play-free Connection
              • Unlimited use of the Watt gear system is possible
            • Input shaft

            • Gear systems with input unit (-WN) allow the running of WATT MAS® gear unit via the extension of drive unit elements such as coupling, belts or chains.

              This gear system with input shafts is an economical solution if the input motor cannot be assembled directly next to the gear unit.

              Possible field of application:
              • As subsequent ratio for shafts that are already slow or running at engine speed!
              • Manual input for regulating or adjusting movements.
              • To synchronize mechanically, for multiple drive units by using a common input shaft.
              • Also for gear units that are driven from output (turbine gear units for generator drive units).
              • For gear units that are under considerable load, such as in the field of chopper machines, whereby liquids or couplers for excessive loads between the motor and gear unit are implemented!
              • Drive units between motor and gear units that require additional mechanical brakes for safety reasons (stage technology, hoisting devices…)
              • Drive units whereby the motors are mounted separately for environmental reasons. (Ex-areas, areas where there is no power supply).
          • Modular System motors

          • A Motor for 100Hz Characteristic and Any Voltage Worldwide!

            WATT EUSAS® motors are top quality, three-phase AC industrial motors from Watt Drive’s customer-oriented motor system. EUSAS® stands for EUrope - USA - ASia and means that the wide voltage range and simple voltage selector in the terminal box enable the motor to be operated with virtually any supply voltage and frequency worldwide.

            100 Hz Characteristic - Double Power:
            In frequency inverter operation WATT EUSAS® motors can be controlled using the 87/100/120 Hz voltage/frequency characteristic without special windings. As a result, the same motor size can output up to double the power without being overloaded.

            Connection Modes:
            The Watt Drive quality motor uses a 9-pin terminal block and therefore can be switched in star, delta, double star and double delta with its wide-range winding. This way, the motor still covers a large part of worldwide supply voltages. EUSAS® motors up to incl. frame size 100 can be operated in the following voltage range: 220-240V (D), 110-120V (DD), 380-420V (Y) and 190-210V (YY). From frame size 112 following voltage ranges are possible: 380-420V (D), 190-210V (DD), 660-690V (Y) and 330-365V (YY) each for 50 and 60Hz.
              • Integral motors

              • The EUSAS® integral motor is part of the WATT motor system. All features and benefits have been implemented and further developed. The motor is robust, in keeping with the high demands made by the industry and in the short term is capable of excessive loads.

                The motors are equipped with a reinforced suspension and are directly built into the gear units, resulting in a very short, compact design.

                The standard is equipped with a brake end plate as NDE-side (non driven end side). By using the standardized motor modules (for more information see “Motor systems”), customer-specific solutions can be implemented quickly and economically.

            • The type series F.. RX 8.. (parallel shaft gears) and K.. RX 8.. (bevel gears) are available with torques of up to 120kNM.

              The drives can be implemented in many branches of modern engineering, like e.g. the conveying or environmental technology. With such vigorous packages, serial products, as well as customer optimised drive solutions, can be realised quickly and market-conform. Watt Drive is planning the optimal, machinery oriented drive selection together with the customer. A successful realisation of the project targets is the most important feature of our philosophy.
                • Parallel shaft gear units

                • Innovative total solutions up to 120 kNm.

                  The parallel shaft gear units F.. RX 8.. have a 1 - 4 stage design and therefore cover a large reduction range. The thermal power limit of the gear units are between 5.5 kW and max. 445 kW.

                  The motor mounting is established with an IEC adapter with coupling. The housings are worked on all sides so that they can be used for every mounting position. They are standardly manufactured of grey cast iron EN-GJL-250. The gears can be implemented either as shaft mounted gears with hollow shaft as well as parallel shaft gears with output shafts. Precisely manufactured gearwheels with involute profile guarantee high efficiencies and a low-noise running.

                  The bevel gears K.. RX 8.. are designed 2 to 4-staged by which thermal power limits from 14 - 304kW are covered.

                  With bevel gear motors, an IEC adapter with coupling establishes the motor mounting. The input level of those drives built the bevel level so that a swivelling of the input shaft is possible. Thus more mounting positions can be established, which is of a great advantage in case of a small mounting space. The housings are worked on every side like the parallel shaft gears and have the same mounting dimensions at the same size.
