DM 45K 9301-D

The DM 45K 9301-D, Bosch Rexroth Indramat, DM Servo Drives opens the discussion for a high-performance servo drive module engineered for precision motion control. This three-phase module features air cooling and integrated feedback via a Resolver encoder, optimizing it for synchronous, linear, and asynchronous motor operation. Its modular design is part of the Servodyn-D family, allowing easy integration into digital inverter systems with supply and axis modules. Certified two-channel safety structure and redundant electronics ensure compliant operation in demanding industrial environments.

In terms of detailed specifications, the drive accepts an Input Voltage of 670V and delivers a continuous Module Current Rating of 45 A at a 2 kHz switching frequency. It maintains full performance within an Ambient Operating Temperature range of 32 … 113 °F, with automatic current derating above this limit and restoration as temperatures fall. For storage and transport, the unit withstands Storage Temperature extremes from –13 °C … 158 °C and should be kept clear of corrosive gases and metal vapors. The compact housing carries an IP20 protection rating and weighs approximately 14.7 lb, while Bosch recommends a 100 mm clearance around the module to ensure adequate airflow and heat dissipation.

Integration of the DM 45K 9301-D into existing Servodyn-D systems is seamless, thanks to its native CANopen and CANrho interfaces and plug-in architecture. The robust air-cooled design offers high reliability with minimal maintenance, reducing downtime in production lines. Ideal for machine builders requiring scalable motion control, this drive module supports swift commissioning, safety compliance, and long-term operational stability.
