If your system architecture requires a drive solution that implements top speed, we would recommend our SPIROPLAN® right-angle gearmotors: space-saving and simple to install.

The special, wear-free SPIROPLAN® gearing offers you a largely vibration-free drive with low weight and high efficiency. Excellent smooth running properties are achieved as a result of this gearing and steel on steel combination of the tooth elements.

The SPIROPLAN® right-angle gear units are also maintenance-free thanks to their practical lubrication for life and help you to reduce the ongoing operating costs of your system. They are real lightweights thanks to their aluminum housing, with which you can of course implement any mounting position you wish.

Be it with hollow shaft or solid shaft, we offer a diverse range of mounting and extension options and motor combinations according to your individual requirement profile. The SPIROPLAN® right-angle gearmotors meet the requirements for energy efficiency classes IE1 to IE4 so that you can use them anywhere in the world.

By opting for one of our gearmotors, you are already saving time and money with this selection and project planning. This is because our modular system enables a multitude of combination options for gear units and motors. You can therefore reduce operating costs, count on a long service life and benefit from simplified maintenance that is characteristic of our brand.
