DM 45K 9101-D

The DM 45K 9101-D from Bosch Rexroth Indramat belongs to the DM Servo Drives and delivers a robust three-phase module solution for demanding motion applications. It supports a peak 45 A current output at a 2 kHz switching frequency, enabling precise control of linear, synchronous and asynchronous motors. Compact mechanics and an onboard air cooled scheme ensure high performance in tight cabinet spaces. Designed for integration in Servodyn-D inverter systems, it features a sturdy IP20 enclosure for industrial environments.

Engineered for high-voltage DC link applications, this drive accepts a 670 V input and regulates to 670 V DC (regulated) or 715 V DC (unregulated) at up to 45 A continuous current. It offers dual communication via CANopen and CANrho interfaces and a Standard encoder port for real-time feedback. Under overload, it sustains up to 47.5 A at 4 kHz and 35 A at 8 kHz, while continuous currents range from 23.5 A at 4 kHz to 16.5 A at 8 kHz. The module draws 1.4 A from a 24 V auxiliary supply and dissipates a maximum 205 W of power loss, all within a 75 mm footprint weighing 6.7 kg.

Integration into automation systems is seamless: the DM 45K 9101-D mates directly with Bosch SF, SR or DU motor lines, reducing panel wiring and simplifying commissioning. Its IP20 rating—when mounted in an IP54 cabinet—along with operation from 0 °C to 45 °C and elevation limits to 1000 m, guarantees reliable long-term performance. A one-year global warranty and compliance with industrial safety standards ensure consistent uptime and serviceability for high-duty-cycle applications.
