Product Description:

The MS2N03-D0BYN-AMDL0-N-NNNN-NN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MS2N Synchronous Servo Motors series. It carries the MS2N03 size designation, uses frame length D, and is built with standard design features and standard flange accuracy. The mechanical layout follows the B5 / IM3001 form and incorporates a PT1000 temperature sensor. Self-cooling is provided by a housing finished in standard RAL 9005 black varnish. Power and feedback are routed through a rotatable double-cable connection with two M17 plugs. The unit is supplied without a holding brake, has a keyed shaft without a sealing ring, relies on a low-inertia rotor, and has a total mass of 2.0 kg.

During operation, the motor can reach 9000 rpm; this is also its rated speed for continuous duty. At a 100 K winding rise, it delivers 0.4 kW, while short-time output peaks at 6.8 Nm. The torque constant is 0.6 Nm/A, and the current controller must stay within 14.5 A to avoid thermal overload. Phase resistance is 6.29 Ω at 20 °C; together with a winding inductance of 9.56 mH and a voltage constant of 36.2 V per 1000 rpm, these values describe the electrical behavior of the winding. When the stator is limited to 60 K, continuous standstill torque is 1.15 Nm. Encoder performance is Basic with 16 signal periods on a Hiperface interface, providing mid-range speed feedback.

At a 100 K temperature rise, the motor sustains 1.45 Nm of standstill torque, and it can reach a peak of 7.4 Nm for rapid acceleration because of its low rotor inertia. Absolute position retention is provided by a multi-turn encoder capable of 4,096 revolutions, allowing the axis to power up without homing. Mechanical connection is handled by a shaft measuring 11 × 23 mm that accepts a 4 × 16 × 2.5 mm keyway, which supports secure torque transmission in compact automation assemblies.
