MS2E04-C0BNN-CMSK1-NNNNN-NN by Bosch Rexroth Indramat

The MS2E04-C0BNN-CMSK1-NNNNN-NN is a synchronous servo motor in the MS2E series produced by Bosch Rexroth Indramat. It is a three-phase permanent-magnet unit intended to drive precision axes in industrial automation, converting electrical energy into controlled rotary motion for robots, conveyors, and tooling spindles. The motor has frame size 04 and length code C.

Rated output parameters describe the continuous operating point. The motor delivers 0.55 kW of mechanical power while producing 1.62 Nm at the shaft and drawing 1.1 A from the drive at a nominal speed of 3000 rpm. For transient demand, the standstill torque is 2.80 Nm, and overload capacity reaches 13.05 Nm with a peak current of 9.7 A. A maximum mechanical speed of 6000 rpm is permitted. Magnetic performance is characterized by a torque constant of 1.74 Nm/A and a voltage constant of 105.7 V per 1000 rpm. Low rotor inertia supports fast acceleration, while self-cooling and a deep-groove ball bearing help maintain temperature and mechanical stability. A PT1000 sensor monitors winding temperature for closed-loop thermal protection.

An electrically released size 1 brake provides 5.00 Nm of holding torque when supplied with 24 V DC, helping prevent drift when the drive is disabled. Position feedback is provided by an Advanced Performance ACUROlink multi-turn encoder with 20-bit single-turn resolution and storage for 4096 absolute revolutions. A single rotatable M23 hybrid connector simplifies cabling. The assembly is finished in RAL 9005, weighs 4.4 kg, and carries an IP65 rating, with a keyed shaft and sealing ring for ingress control. Installation uses B5 / IM3001 mounting with an 82 mm flange, a 95 mm hole circle, 6.6 mm bolt holes, and a 50 mm centering collar. Standard flange accuracy is maintained, and operation is permitted from 0 °C to 40 °C without derating and up to 1000 m altitude. ATEX compliance allows use in regulated atmospheres.
