The R911307311 (MHD095B-058-PG1-AN) is a synchronous motor from Bosch Rexroth's MHD series, featuring a digital servo feedback mechanism with integrated multiturn absolute encoder and a winding code of 058. The design features a 22Nm holding brake, a plain shaft with a sealing ring, and an A-side power output direction. The cooling system is equipped for natural convection and surface cooling. Electrical and mechanical data are recorded for various levels of cooling and motor temperatures. Key parameters include continuous current at standstill (ranging from 22.8A to 34.2A) and continuous torque at standstill (varying between 17Nm and 25.5Nm). The motor is fitted with four pole pairs. Its rated data include current, performance, voltage and torque, whilst also consisting of a constant rated speed and frequency. Operation conditions recommend an ambient temperature between 0-40 degrees Celsius, with storage conditions between -20-80 degrees Celsius. The motor comes with a global one year warranty.
