Motor brakes that eliminate pitch drive maintenance

The Magnashear motor brake from Force Control Industries eliminate pitch drive maintenance by eliminating the root cause of maintenance required for traditional dry braking systems, degradation of friction material. Oil Shear technology is a unique technology which transmits torque between lubricated surfaces, thereby eliminating wear on friction surfaces. A fluid recirculation system dissipates heat thus eliminating heat build-up which causes friction material glazing, another common problem in dry braking systems which requires adjustment. Oil Shear eliminates the wear and thus the need for adjustment, and significantly increases service life (typically to 5-10x that of dry braking systems). Oil shear technology also provides a smooth cushioned stop which reduces shock to the drive system, further extending service life of downstream components. The totally enclosed, IP56 rated, Magnashear brakes are impervious to moisture, dirt, and dust and are suitable for critical wind turbine applications such as pitch drive systems.
