Product Description:
The SE-B4.210.030-04.000 is a synchronous servo motor in the SE Synchronous Servo Motors series from Bosch Rexroth Indramat. Within industrial automation, this rotating actuator converts commanded electrical energy into precise motion for positioning tables, gantries, and processing heads while working with drives that regulate speed, torque, and position through feedback. The frame and winding combination place it in medium-capacity axes commonly found in assembly cells, packaging equipment, and material-handling stations where repeatable rotary movement is required. Its intended use centers on controlled motion tasks that need consistent response during indexing, positioning, and speed changes.
Its mounting interface follows the IM B5 construction format, giving a circular flange that aligns with machines through a 142 mm bolt circle while meeting the IEC 72-2 and DIN 42 948 dimensional code. A Ø24 × 50 mm shaft projects from the flange, and the keyway with feather key provides positive torque transfer to couplings. This shaft arrangement helps the motor connect securely to driven components without relying only on friction at the hub. Dynamic loads are accommodated by a shock limit of 6 g, and airborne acoustic emission is restricted to 58 dB(A). Designed rolling elements endure 20,000 h of service life, and the bearing system, cooling path, and balanced rotor help control vibration during repeated acceleration and deceleration.
The holding device is an electromagnetic brake that produces 18 Nm of torque to secure vertical axes when power is removed. It operates from a 24 VDC ±10 % supply and draws 1.0 A during coil excitation, allowing quick brake release during normal drive operation. Rotor inertia added by the brake is 0.90 × 10⁻³ kg·m², so it must be considered when calculating acceleration and deceleration behavior. Heat-resistant materials tolerate temperatures from -10 to +145 °C within the motor assembly. This supports reliable brake and motor operation where internal temperatures rise during repeated cycling.
