MAD100D-0250-SA-S0-AH1-05-N1

The Bosch Rexroth Indramat MAD100D-0250-SA-S0-AH1-05-N1 is a high-performance spindle Servo Motor within the MAD IndraDyn A Motors series designed for demanding industrial motion control applications. This unit delivers a rated torque of 50 Nm at a rated speed of 2500 rpm and can sustain peak speeds up to 9000 rpm thanks to its robust drive design. Constructed with a Flange mounting style and a Motor Frame Size 100 combined with a Motor Frame Length D, the unit integrates seamlessly into standardized machine interfaces. Cooling is managed via an Axial fan blowing system, while protection of critical components is ensured by a Standard deep-groove ball Bearing Type. Position feedback is provided by a Singleturn absolute encoder with 2048 increments, offering precise angular resolution for closed-loop control. The connection topology features a reinforced power interface on the A-side Connection with a minimum power wire cross section area of 6 mm2 to guarantee reliable electrical contact.

Performance characteristics emphasize the motor’s dynamic response and energy efficiency. The torque constant of 2.04 Nm/A at 20 °C underpins predictable torque generation, and the 3 pole pairs architecture ensures smooth synchronous operation. The rotor possesses a moment of inertia (excl. brake) of 0.0392 kg·m2, optimizing acceleration and deceleration cycles, while the auxiliary electrically-released Holding Brake adds 0.000556 kg·m2 to the inertia when engaged, with a maximum braking speed of 10000 rpm. Mechanical robustness is further highlighted by the Smooth shaft without shaft seal, providing a non-floating shaft–hub connection rated to vibration grade R. Electrical parameters are stable across the operating envelope, and peak torque capability reaches 118.7 Nm at maximum speed conditions.

Reliability is engineered through stringent quality control and maintenance-free operation when used within the prescribed parameters. All units undergo comprehensive electrical and mechanical testing to certify performance and endurance. The absence of a sealing ring simplifies service and minimizes downtime, while compatibility with standard deep-groove bearings ensures high parts availability. Integration is simplified by industry-standard mounting and connection conventions, facilitating retrofit into existing motion systems or new machine designs. Ideal applications include CNC machining spindles, rotary indexing tables, and precision assembly equipment where sustained high speed, accurate torque control, and long service life are paramount.
