Product Description:

The MDD041A-N-100-N2K-050GB1 is a synchronous servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers rapid rotary motion for compact handling modules, labeling heads, or spindle drives where finely resolved speed control and position feedback are essential to overall machine coordination. The motor length code is A, reflecting the shortest stator stack in this frame.

A centering boss of 50 mm supports precise flange alignment, while the rotor is factory balanced to the standard grade to limit vibration at the rated shaft speed of 10000 rpm. The stator can maintain a continuous standstill torque of 0.64 Nm, giving the axis enough holding capability during dwell periods without thermal overload. Motion feedback is delivered by an onboard integrated absolute encoder, and its multiturn position data eliminates the need for homing after power cycles. For power-off safety and vertical loads, a blocked-rotor brake supplies 1.2 Nm of static torque and is released through the drive control when motion is commanded. Resolver-based diagnostics travel through the secondary channel, and the motor also provides resolver feedback for drives that require analog sinusoidal position information.

The motor uses a plain shaft geometry that mates with friction or collet couplings. All electrical terminations exit on side B so cable trays can be routed consistently along the machine frame. The frame identification of 041 keeps the overall diameter low, helping designers place multiple axes in tight clusters. A sealed housing with a shaft seal helps prevent lubricant escape, and a single keyed circular connector carries both power and feedback leads. A standard shaft end on the drive side and the absence of a secondary shaft on side B simplify guarding arrangements.
