Product Description:

The MS2M04-B0FNN-KMDL0 is an ultra-compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. It is designed for industrial automation axes that demand high torque density, small mounting envelopes, and accurate position feedback. Within such systems, the motor converts electrical power into controlled rotary motion, while its integrated optical encoder returns absolute position data to the drive so that PLCs can execute repeatable moves without auxiliary sensors.

Rated output reaches 1 kW, a continuous power level achieved at the base speed of 3000 rpm. At that operating point, the shaft delivers 3.18 Nm, and the phase current is limited to 5.7 A (rms). Heat is removed by natural convection, eliminating fans and reducing maintenance requirements. Low rotor inertia improves acceleration response, while the motor has frame size 4 and length B to fit compact machine frames. Power and feedback connections use an M17 quick-lock SPEEDCON connector, and a double-metal lead wire cable shields the encoder signals. The optical sensor offers 23-bit resolution and is available with single-turn or multi-turn position tracking. Its electronics operate from a supply voltage of 4.75 to 5.25 V.

For short overloads, the drive can furnish 17.13 A (rms), allowing the motor to produce up to 9.55 Nm of peak torque. The IP65 enclosure blocks dust and resists water jets, while reliable operation is permitted within an ambient temperature range of 0 to 40 °C. Five pole pairs generate smooth torque with minimal cogging. This motor is supplied without a holding brake, so an external mechanism or drive-applied torque is required when a stationary load must be retained. The keyed shaft is delivered without a sealing ring for direct coupling to gearboxes or pulleys. Acoustic emissions remain below 65 dB(A), reducing motor noise in installations located near operators.
