We offer project planning of your required drive (required torque, power, speed, etc.) in addition to the geared motors.SEW Sales Department
Standard geared motorsThree-phase electric motors with the following gear types cover the widest range of all possible applications.
Spiroplan geared motors
From 0.09 kW to 4 kW or from 25 to 180 Nm.
Axis of the output shaft perpendicular to the motor rotation axis.
Apart from the fact that gear units and motors can be of different dimensions/equipment, there are other important features depending on the use of the gear motor. We will be pleased to advise you!
- Spatial position/design
Attention please: Depending on the spatial position of the geared motor (installed / in three-dimensional space), a sufficient filling level with oil must be ensured. All teeth, rolling bearings, etc. must be immersed in oil by revolutions and completely lubricated.
- The spatial position determines the design: foot, flange or in a few cases even both.
While the gearbox is very heat stable, the engine must be sufficiently cooled.
Normally, a geared motor cools itself. In exceptional cases, a forced cooling fan must be fitted.
- Position terminal box / cable entry connector position
This point again concerns the nature of the site. Of course, one would like to have good cable accessibility. The position of the terminal box on the motor and the cable entry should be well planned.
- With & without brake (SEW-brakes & brake rectifier)
- With & without tacho transmitter (for operating the geared motor via frequency converter)
- With explosion-proof three-phase motors (ATEX) for use in potentially explosive atmospheres (EU Directive 94/9/EC (ATEX), or from 20.04.2016 on EU Directive 2014/34/EU (ATEX))
- Temperature sensor
- Aseptic gear motors
In some applications like:
- Food, luxury food and beverage industry
- Chemical / pharmaceutical industry
- Dairy / Cheese factory
special hygiene regulations must be observed. Gearmotor housings must be cleaned regularly and even treated with disinfectant . For this reason, they must be closed and the surface must be painted accordingly. In addition, aseptic gearmotors are larger in size because they do not require ventilation and the heat can only be dissipated via the larger surface of the housing.
Special gear motorsWe also distribute gear motors for less common applications in industry and large scale industry.
up to 3,000 Nm
Industrial gear units up to 600,000 Nm
up to 1,400,000 Nm
We generally recommend drive technology from SEW. We can also fulfill special customer requirements (other manufacturers) due to our extensive product portfolio. We can therefore also offer you gear units and gearmotors from the following manufacturers:
