Solar technology with Baumüller disc motors

Nuremberg. Exact positioning accuracy, high dynamic response within the speed control range, and a high level of long-term stability – these are the requirements that must be fulfilled by drives used in solar technology. Baumüller disc drives feature these exact characteristics and are thus predestined for applications in this sector.

The demand for renewable energy is constant as always. Solar energy, in particular, is ever growing in popularity. In contrast to fossil fuels, the amount of photovoltaic- or thermally-produced solar energy available is practically unlimited. And, this technology releases no CO2 or fine dust, such as soot particles.

Stringent requirements for drive technology

The solar industry places very stringent requirements on its drive technology. In addition to exact positioning accuracy and a high dynamic response, the drives must exhibit a high level of long-term stability.

Baumüller disc motors fulfill these requirements. First, they exhibit low torque ripple, which enables them to feature smooth synchronization. Second, they are easy to control and feature exact positioning accuracy. For example, during adjustment of the solar panels to follow the progression of the sun, the optimum angle of incidence for solar radiation can be ensured.

In addition, the high dynamic response of the disc motors within the speed control range makes them optimally suited to move the solar panels to a safe position in the event of large environmental variations, such as high wind conditions.

Brushless disc motors are characterized by their long service life. Because wear-prone components are eliminated and due to the very high level of long-term stability, expenses for service and maintenance are minimized.

Upon request, Baumüller provides disc motors as integrated units and can supply complete drive units, consisting of a gearbox, encoder/tachometer, and brake. This optimizes the interfaces in the system and minimizes the susceptibility to errors significantly.
