Product Description:

The MS2N05-D0BRN-AMDG1-NNANN-NN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MS2N Synchronous Servo Motors series. It has size MS2N05 and frame length D, giving it a compact format with low rotor inertia for fast indexing tasks in packaging, handling, and assembly equipment. The motor uses self-cooling, and its 8.4 kg mass supports installation on lighter machine axes. A smooth shaft with a sealing ring helps protect the interior, while the Size 1 electrically released holding brake secures vertical loads at standstill. Power and feedback pass through a rotatable double-cable M17 connection that helps simplify cable routing in enclosed machine spaces.

Standard bearings support continuous duty, and a black RAL 9005 varnish helps protect the housing from oil and dust. A basic Hiperface encoder with 16 signal periods provides multi-turn absolute feedback over 4,096 revolutions, so position information remains available after power loss. Under rated thermal conditions, the motor draws 3.95 A and delivers 1.74 kW at a shaft speed of 4500 rpm, producing 4.74 Nm of continuous torque. Winding resistance of 1.76 Ω helps limit copper losses, while a permissible current peak of 30.3 A allows the controller to reach the mechanical top speed of 6000 rpm during short accelerations. This operating range suits servo axes that require quick response during repeated start-and-stop motion.

Short-term overloads are handled by a cold-start reserve of 34.0 Nm, and when motion stops, the electromagnetic circuit can sustain 9.35 Nm without thermal drift. Torque increases at 1.4 Nm/A, and the back EMF characteristic of 84.8 V/1000 rpm gives the drive a predictable voltage relationship during closed-loop regulation. Flange accuracy follows the standard tolerance used in the series, and the motor has a standard mechanical layout. These features support consistent installation on machines that use the same mounting pattern and feedback architecture.
