1MS270C-4B-A1/S040

The Bosch Rexroth Indramat 1MS270C-4B-A1/S040 from the 1MB High-Speed Asynchronous Motors series features a motor size of 270 and a motor length designation of C, combined with a windings code of 4B for optimized performance. Designed for high-speed applications, this stator incorporates an aluminum cooling jacket for liquid cooling and built-in PTC and NTC resistors to support seamless integration with third-party drive controllers. An integral 1 500 cm cable provides reliable electrical connectivity, while the compact dimensions of 300 × 400 × 120 mm facilitate straightforward mounting in machine tool spindles and high-speed rotary devices. Robust construction and precision engineering ensure stable operation at elevated speeds.

Operating at a rated speed of 1 500 rpm and capable of reaching a maximum speed of 6 000 rpm, the 1MS270C-4B-A1/S040 produces a rated torque of 190 Nm and delivers continuous power output of 30 kW. The stator supports a current rating of 96 A and works in concert with a rotor moment of inertia of 0.258 kgm2 to maintain dynamic responsiveness under varying load conditions. An IP00 protection class enclosure and insulation class F winding insulation (per DIN VDE 0530-1) provide basic environmental protection and thermal endurance in ambient temperatures from 0 °C to 40 °C.

Weighing 82 kg and specified for installation at altitudes up to 1 000 m, the 1MS270C-4B-A1/S040 is engineered for reliable, high-speed duty cycles. Backed by a one-year warranty, this Bosch Rexroth Indramat stator offers an economical, high-performance solution for high-precision automation, spindle drives, and rapid indexing systems.
