Product Description:

The MDD093C-N-020-N2M-130PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It interfaces with digital drive controllers to convert commanded current into precise rotary motion, making it suitable for positioning tables, pick-and-place gantries, and similar automation axes where repeatable velocity and torque are required. The C-length stator stack in the size-093 frame provides higher continuous torque while preserving mounting compatibility across the series. This arrangement supports accurate starts, stops, and speed changes in automated handling systems.

A centering pilot of 130 mm aligns the motor flange concentrically with the driven machine frame, reducing runout that could lead to vibration. Power and feedback cables are routed on side B through a sealed connector, which can simplify cabinet layouts when multiple axes are stacked in line. The motor reaches a nominal mechanical speed of 2000 rpm, enabling direct shaft coupling to low-ratio gearboxes or timing belts without overspeeding the rotor. Position data is supplied by an integrated multi-turn absolute encoder, allowing operation without a homing cycle after power-up. The feedback link uses digital servo feedback, which transmits position, speed, and temperature data over a single serial channel. A blocking brake rated at 11 Nm holds the load when the controller is disabled, helping prevent drift on vertical or rotary tables during power loss.

Protection against coolant splash is provided by a shaft seal that guards the front bearing, and the standard cast housing maintains enclosure integrity. The output shaft uses a keyway, which provides positive torque transfer and supports repeatable hub mounting. That layout suits couplings that need a fixed angular relationship between the shaft and the driven hub. The rotor uses standard balancing, which keeps residual vibration low during cyclic acceleration and helps preserve stable encoder operation. The sealed front end also helps limit contamination at the bearing seat in splash-prone machine areas.
