Product Description:

The MDD041B-N-100-N2G-050PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it supplies precise rotary motion and feedback to compact automation stations such as indexing tables, electronics assembly heads, and light machining spindles. Its synchronous design supports accurate speed and position control in compact axes where rapid starts, stops, and small correction moves are common. This makes the motor suitable for tightly packed machine layouts that still require repeatable motion and stable closed-loop behavior.

In continuous duty, the motor delivers 1.35 Nm of torque at standstill, allowing stable holding and fine interpolation without thermal overload. A rated speed of 10,000 rpm suits high-throughput machinery, while standard balancing keeps radial vibration low across that speed range. The compact 041 frame with length code B reduces rotor inertia for rapid acceleration, which helps the axis respond quickly to command changes. A centering diameter of 50 mm provides a true-running pilot surface for flange mounting, and power is transmitted through a keyway on the single drive-side shaft. The opposite end remains closed, which keeps the overall package short.

Electrical terminations are concentrated in a single connector, and those connections exit on side B, which simplifies cable routing in tight cabinets or closely spaced machine sections. Closed-loop operation uses resolver feedback to return rotor position during rapid reversals, so the drive can maintain controlled motion through repeated direction changes. The motor is supplied without a blocking brake, so vertical loads require an external holding method when power is removed. Protection against lubricant migration and airborne particulates is provided by a shaft seal at the output journal, and the standard cast-aluminum housing dissipates heat passively during operation.
