MDD025C-N-100-N2K-040FR0
The MDD025C-N-100-N2K-040FR0 is a brushless servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for integration with digital drive controllers, it translates commanded current into accurately regulated rotation so automated pick-and-place modules, small gantries, or packaging axes can maintain repeatable position and speed profiles on every cycle. Its 025 frame size and C length code keep overall mass low, which helps the motor fit compact machine layouts where space is limited.
The rotor uses standard balancing, which keeps vibration within limits suited to high-speed operation. A centering collar of 40 mm simplifies concentric mounting to gearboxes or flanges, while the power and feedback leads exit to the right side to reduce cable loops in tight panels. The motor uses a single plug-in connector that combines phase conductors and signal cores in one connection. At standstill, the electromagnetic circuit produces 0.90 Nm of continuous torque, giving adequate holding force for light indexing loads without oversizing the axis. Because the unit is supplied without a blocking brake, any power-off holding requirements must be handled by the drive or by external mechanical restraint, and the standard aluminum housing provides passive cooling for continuous duty under typical ambient conditions.
The magnetic design supports a rated speed of 10,000 rpm, allowing rapid traverse moves when paired with a matching inverter. Position data is derived from an integrated absolute encoder, and the drive receives additional fine-angle information through resolver feedback for commutation. Output torque is delivered through a plain shaft that omits keyways to minimize runout, and the shaft end on side B is omitted to shorten the package depth. The front bearing area is built without a shaft seal, so the motor should be mounted in clean environments or provided with an external sealing element if splash exposure is expected.
