B&R Industrial Automation recently announced the addition of precision planetary gears to its line of synchronous and stepper motors. The result is a high performance and economical drive program for all industrial fields that can be optimized to meet customers' needs and is provided from a single supplier. B&R developed a motor-gear building block principle together with German manufacturer Neugart. The planetary gears are delivered fully mounted on B&R's 8LSA, 8LVA, 8JSA and 80MP series motors. Gears in both straight and angled designs and with all conventional drive flange geometries were developed together with Neugart as the technology partner. The standard gears are single-stage for gear ratios I= 3, 4, 5, 8 and 10 and have less than 8 - 15 arcmin backlash. The gears are also offered in two-stage or three-stage designs. At the top of the product line, the premium series provides backlash less than 1 arcmin as an option paired with high output torques.
