Product Description:

The MSS202D-0360-FA-N0CN-NNNN is a water-cooled synchronous servomotor produced by Bosch Rexroth Indramat for the MSS Synchronous IndraDyn H Motors series. It serves as a direct-drive torque source in industrial automation, allowing machine builders to couple the rotor directly to spindles or linear actuators without intermediate gearboxes. The open IP00 housing is intended for installation inside a guarded enclosure, where the integrated cooling jacket removes heat and maintains consistent magnetic performance during high-duty cycles.

At its nominal operating point, the motor runs at 3600 rpm, delivers 51.3 kW of mechanical power, produces 136 Nm of continuous shaft torque, and draws 102 A of phase current. A low winding resistance of 0.10 Ω limits copper losses, improving efficiency at sustained loads. For transient demands, the electromagnetic design supports up to 333 Nm, providing extra capacity for acceleration or process peaks. Thermal stability is supported by a 315 mm cooling jacket fed through G 1/4 ports that tolerate 6 bar of internal pressure. This water circuit can remove heat rapidly throughout continuous operation.

Dynamic peaks require 197 A, so the drive inverter must accommodate this current without clipping. Torque rises linearly with a constant of 1.70 Nm/A, enabling predictable control tuning, and the back EMF follows a voltage constant of 113.8 V/1000 rpm, which helps establish regenerative braking limits. A frame diameter of 220 mm provides a compact profile relative to the motor’s torque density, easing integration with machine flanges. Because the unit relies on water for thermal management, continuous coolant flow keeps the magnets and bearings within their thermal limits during rapid speed changes and high cycle rates.
