Product Description:

The MDD025C-N-100-N2G-040MC1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it supplies rotational energy for fast axes in automated machinery. In industrial automation, this unit converts controlled electrical power from the drive into mechanical motion, enabling positioning, speed control, and braking tasks on assembly lines, PCB handlers, and robots. Its small frame size supports installations where footprint and inertia must be kept low while still allowing high spindle velocities in compact equipment.

At a nominal speed of 10,000 rpm, the rotor can sustain rapid cycles suitable for pick-and-place or light machining operations. When the shaft is locked, it can develop a continuous stall torque of 0.90 Nm, allowing the axis to hold static loads without overheating. The integrated blocking brake adds an emergency stop torque of 1.0 Nm to secure vertical stages during power loss. All electrical and encoder terminations are routed toward Side A, which can simplify cabinet layout, and the 40 mm centering pilot keeps the flange concentric with the gearbox or mounting plate. Velocity and position are returned to the controller through resolver feedback, providing analog sine-cosine signals with good noise resistance.

A splined drive is unnecessary because the shaft uses a keyway, which provides positive torque transmission to couplings or pulleys. Power is supplied through a connecting cable with a coupling unit, so the motor connects through a preassembled interface rather than individual pin wiring. Because the design is without a shaft seal, the model is intended for clean environments where fluid ingress is not expected, and this omission helps reduce friction and bearing temperature. The motor uses a standard housing and standard dynamic balancing to keep vibration low. Its 025 frame size and C-length body also shorten the overall stack for space-critical installations, and the shaft is finished only on the drive end to avoid a side-B extension.
