Integrated stainless-steel drive offers high power densities

07 April, 2010

The German motor manufacturer Groschopp has developed a servomotor in a stainless steel housing which also incorporates a reduction gear and control electronics. The Silver Line motors, with ratings up to 2.3kW and 5.5Nm, are aimed at applications such as driving conveyor belts in the food, beverage and pharmaceutical industries.

The integrated design (shown above) is said to save space, material and assembly time, while the coil winding technology used in the motors is said to result in an output density which is twice that of other servomotors.

The corrosion-resistant stainless steel housing has no screw connections or holes, and the socket for the plug connection is welded into place. O-ring seals and plastic plugs help to provide a smooth, rounded surface, resulting in a protection rating of at least IP65, and possibly IP69K.

The system’s wormgear is also made out of stainless steel, including its driveshaft, and is filled with lubricants suitable for the food industry.

The Silver Line motors are optionally available without integrated electronics, allowing customers to use their own controllers.
