Product Description:
The MDD041A-N-100-N2K-050GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers and converts drive current into precise rotary motion for automation axes that need fast acceleration, compact size, and continuous closed-loop control. It is intended for servo-driven packaging, handling, and light assembly equipment where the drive must maintain stable position control during repeated motion cycles. The rotor uses standard dynamic balancing, which helps limit vibration at operating speed and protect bearings and connected mechanics.
A centering pilot of 50 mm aligns the flange accurately on gearboxes or mounting plates. Power and feedback leads leave the unit on Side A through a keyed connector, keeping cable routing in a single direction. With 0.64 Nm of continuous standstill torque, the motor can hold tension on light loads without overheating, while its rated speed of 10000 rpm supports high-throughput positioning tasks. The internal stator windings are paired with resolver feedback, delivering analog sine-cosine signals that allow the controller to resolve rotor position over each electrical cycle. The housing uses standard cast construction, and the compact A-length body under size code 041 fits into tight machine spaces such as transfer units and small slides.
For static holding, the unit is delivered with a blocking brake that supplies 1.2 Nm of holding torque when the drive is disabled, helping prevent back-driving on vertical or inertia-loaded axes. An integrated absolute encoder provides true position data immediately after power-up, removing the need for homing moves and complementing the resolver used during motion. Output torque is transmitted through a plain shaft, and the shaft end is only on the drive side to reduce overall length. A dedicated shaft seal blocks coolant splash and dust from entering the front bearing so the standard housing can maintain a clean internal environment during high-speed operation.
