MS2E04-C0BNN-CMSK1-NNNNN-NN
MS2E Synchronous Servomotors
The MS2E04-C0BNN-CMSK1-NNNNN-NN is a three-phase permanent-magnet servomotor produced by Bosch Rexroth Indramat within the MS2E Synchronous Servomotors series. Intended for industrial automation tasks, it drives rotary axes that demand explosion-protected equipment in accordance with its ATEX conformity. A self-cooling housing, standard deep-groove ball bearings, and an electrically released holding brake simplify installation, while the single M23 rotatable connector combines power, signal, and brake lines to minimize cabinet wiring.
At nominal conditions the motor supplies a continuous shaft torque of 1.62 Nm while drawing just 1.1 A from the inverter, producing an output of 0.55 kW at its 3000 rpm rated speed. This baseline rating is augmented by a mechanical upper limit of 6000 min⁻¹, providing headroom for quick cycle moves, and by a short-term torque ceiling of 13.05 Nm for acceleration or overload events. These figures guide drive selection so that current peaks and thermal loads stay within the motor’s self-cooling capability. The PT1000 sensor in the stator supplies real-time temperature feedback to the drive for protective shutdown when ambient temperatures approach the specified 0 … 40 °C range.
Closed-loop positioning accuracy is enabled by the Advanced Performance ACUROlink multiturn encoder, which returns single-turn data at 20 bit resolution and tracks 4096 revolutions overall. With a torque sensitivity of 1.74 Nm/A, the drive can calculate current commands that convert directly into predictable mechanical output, an advantage when low rotor inertia is required for dynamic axes. The housing meets IP65 ingress protection with a shaft sealing ring and is coated in RAL 9005 varnish for corrosion resistance. Including the size-1 brake the assembly weighs 4.4 kg, allowing the B5/IM3001 flange to be mounted on machines operating up to 1 000 m above sea level without imposing excessive structural loads.
