1MS270C-4B-A1

1MS270C-4B-A1, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors offers a frameless spindle configuration optimized for demanding motion control. The unit features a Motor Length of C, a Windings Code of 4B, and a Motor Size of 270, ensuring compatibility with high-speed systems. A High-Resolution Position Encoder on the stator delivers precise rotor orientation feedback, while an integrated Temperature Monitoring Sensor maintains thermal stability. Designed for grinding, printing, and other precision applications, this motor aligns with industry standards for robustness and performance.

Technically, the motor achieves a Torque Constant of 2.12 Nm/A and delivers a continuous Torque rating of 190 Nm at speeds up to 6000 rpm. It comprises 2 Polar Pairs with a rotor Moment of Inertia of 0.258 kgm^2, enabling rapid acceleration and deceleration. Supplied via a 1.5 m low-diameter cable rated at 255 V, the stator dissipates a measured Power Loss of 3.6 kW through an Aluminum Cooling Jacket. Weighing 82 kg, the robust construction and precision-lathed housing ensure minimal vibration and optimal heat transfer.

Integration into existing drive systems is simplified by standard stator dimensions and industry-standard electrical interfaces, reducing commissioning time. The closed-loop cooling circuit and built-in thermal sensor guarantee reliable operation under continuous load, while the frameless design allows seamless mounting directly to machine spindles. With global shipping support and a one-year warranty, the 1MS270C-4B-A1 delivers dependable performance for high-speed precision machining and dynamic processing applications.
