SD-B4.070.030-10.000

The Bosch Rexroth Indramat SD-B4.070.030-10.000 is a high-performance member of the SD Magnet Motors series, designed as a permanent-field servomotor for precision motion control in demanding mechanical engineering applications. With a Motor Size of 4 and a reference speed of 3000 rpm, this unit delivers consistent performance and precise synchronization. The Torque Reference Number of 70 ensures the motor can handle moderate torque requirements, making it suitable for use in automated manufacturing equipment where reliable rotary motion and positional accuracy are critical.

Featuring a robust Construction Index B, the SD-B4.070.030-10.000 is built for durability and operational stability. It employs Natural Convection and Thermal Radiation for passive cooling, aided by a low thermal resistance between the stator winding and housing surface to ensure efficient heat dissipation. Vibration performance meets the stringent Vibration Quality Level N as per DIN ISO 2373, while the inclusion of an NTC Thermostat provides thermal monitoring to protect against overheating. Connection versatility is achieved through two plastic connector sockets with aluminum securing rings, allowing for right-angled or straight plug configuration with a prescribed cable diameter. A type label is permanently attached to the housing for clear identification.

This servomotor complies with IP protection standards defined in DIN 40 050/40 053 when used with the correct connector and cable, ensuring reliable operation in dusty or moisture-prone environments. Although it does not support IM V1 mounting (shaft downwards), its design facilitates safe handling of the hot housing surface—use of a touch guard is recommended. In emergency-stop situations, the unit can be rapidly braked by shorting its windings through compatible braking resistors and any of three approved short-circuit braking contactors. Weighing 23 kg, the SD-B4.070.030-10.000 offers exceptional reliability and thermal efficiency, making it an ideal choice for industrial automation systems that demand precise control and long-term operational stability.
