SD-B4.092.020-04.000

The Bosch Rexroth Indramat SD-B4.092.020-04.000 permanent-field servomotor belongs to the SD Magnet Motors series and combines advanced motion control with a backlash-free disk brake. With a nominal speed of 2000 rpm and ferrite magnet material, it delivers consistent performance across its speed-torque curve. This servomotor is primarily designed for integration into Servodyn inverter systems, offering precise torque control and rapid braking for demanding industrial applications.

Boasting a torque constant of 1.53 Nm/A at 40 °C, this unit is engineered for accuracy and reliability. The motor’s overall length of 366 mm and its compact brake assembly enable installation in space-constrained settings. It features fixed ball bearings for robust radial and axial load support, and a brushless tacho style for maintenance-free speed feedback. The IM B5 basic construction, compliant with DIN IEC 34-7, and a permanently attached type label ensure clear identification and easy conformity checks. The fail-safe principle of the disk brake protects operations from unexpected stops by applying permanent magnetic force to the brake armature disk. Protective plastic caps cover the connectors, preventing contamination and ensuring electrical safety.

This servomotor’s flange conforms to DIN 42948 and IEC 72-2 standards, and the cylindrical shaft end, balanced with a featherkey, supports secure coupling. A minimum terminating resistance of 20 kiloOhms safeguards the brake coil, while the integrated brake and power connection simplifies wiring. Vibration Quality Level N ensures compatibility with high-precision environments. Although the housing surface becomes very hot during operation, the motor maintains reduced output only if ambient conditions exceed specified limits. Ideal for industrial automation, the SD-B4.092.020-04.000 offers enhanced durability, efficient operation, and standardized mounting for diverse machinery and production lines.
