The Bosch Rexroth Indramat MAD100B-0150-SA-S2-HP0-05-N1 from the MAD IndraDyn A Motors series is a 4.4 kW servo motor designed for precision and durability in high-performance spindles. It features a 100 frame size and a B frame length offering a compact footprint for space-constrained cabinets with robust flange mounting. The motor incorporates a high-resolution singleturn absolute encoder EnDat2.1 delivering exact position feedback, complemented by a standard bearing type arrangement for reliable rotational support. Cooled by an axial fan and rated to vibration grade R, this design maintains stable thermal and mechanical conditions up to its rated speed of 1500 rpm.
The drive delivers a rated current of 11.8 A and supports a continuous current at standstill of 12.5 A, translating to a solid continuous torque at standstill of 31 Nm. With a torque constant of 3.03 Nm/A at 20 °C and 3 pole pairs, it offers high dynamic response and precise torque control. The B-side connection simplifies wiring in compact assemblies, while the whole-key balanced shaft with seal minimizes vibration and preserves alignment under load. Engineered without a holding brake and optimized for high-speed applications, this servo motor series excels in dynamic machining and automated spindle systems.
As part of the MAD Spindle Motor Series, this product combines advanced encoder technology with robust mechanical design to deliver consistent performance. Its compact dimensions, axial cooling, and precise torque characteristics make it ideal for machine tools, robotic spindles, and automated production systems requiring reliable 4.4 kW power output. The balanced shaft and vibration-resistant construction reduce maintenance intervals, ensuring dependable operation in diverse industrial environments.
