MDD025A-N-100-N2G-040FC0
The MDD025A-N-100-N2G-040FC0 is a compact synchronous motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical commands into precise mechanical rotation for positioning, tracking, and light-load handling tasks in automated machinery. Its A-length frame and 025 size housing keep the mass and mounting envelope small, which helps the motor fit compact servo assemblies on assembly lines, pick-and-place heads, or laboratory automation axes. In typical service, the motor supports short travel moves and repeated start-stop operation where accurate motion is more important than high load capacity.
The mechanical interface starts with a centering seat of 40 mm, which aligns the flange to the machine frame. Power and feedback cables exit on Side A, and the motor is supplied with a connecting cable with coupling unit that mates directly to compatible drive modules. Under continuous stall conditions, it produces 0.33 Nm of torque, providing stable holding force for low-inertia loads. During motion, it can reach a rated speed of 10000 rpm, which supports rapid indexing cycles and quick direction changes. Rotor inertia stays minimal, permitting fast settling on precision tables and helping the axis respond cleanly to frequent speed changes.
The motor is delivered without a blocking brake, so external restraint is required if position holding is needed when power is off. A resolver feedback element is mounted on the rear for closed-loop control, allowing reliable commutation and speed evaluation even under vibration. The drive shaft uses a plain shaft and is shipped without a shaft seal, which suits clean, dry installations where liquid exclusion is not a primary concern. A standard shaft end on the drive side and no extension on side B simplify coupling to miniature gearheads, while residual unbalance remains low at full rated speed.
