The Bosch Rexroth Indramat SD-B3.050.030 05.000 from the SD Magnet Motors series is a robust permanent-field servomotor designed to withstand axial and radial forces on its output shaft while delivering a standstill torque of 5 Nm and a nominal speed of 3000 min-1. This maintenance-free unit features embedded permanent magnets, ball bearings, and an insulation class F for reliable thermal performance between 0 °C and 40 °C. At 392 mm length, it integrates plastic connectors with aluminum securing rings and supports right-angled or straight connector types. The motor includes temperature monitoring and a brushless tacho system with voltage ripple under 1.5% and permits tacho cables up to 100 m, with pin 12 sealed by a blanking plug. Connections to the inverter use housing plug connectors, and braking is effected by shorting windings through external resistors. Installation requires careful heat dissipation and minimum cable cross-sectional areas.
