Product Description:

The MDD041A-N-100-N2G-050GA0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact AC servo unit intended for digital drive controllers and is applied wherever rapid positioning or velocity profiles are required in automated machinery. By combining a high pole-pair rotor with resolver feedback, the motor supplies commutation data to the drive so that torque can be generated without lag during acceleration and deceleration cycles.

The motor can deliver a continuous standstill torque of 0.64 Nm, while its shaft can reach a nominal speed of 10000 min⁻¹ under rated operating conditions. Mechanical dimensions are defined by the Motor Size 041 and the short axial Motor Length Code A, giving machine builders a low-mass actuator for densely packed axes. A centering diameter of 50 mm aligns the flange to mounting faces and keeps runout within tolerance. The plain shaft and the standard shaft end simplify coupling to pinions or pulleys, and the cast housing dissipates copper losses that arise during continuous duty cycles.

Smooth rotation is supported by standard dynamic balancing, and service access is simplified because all electrical terminations sit on Side A behind a keyed circular connector. Position and speed loops are closed with high resolution thanks to the integrated resolver feedback. The unit is supplied without a blocking brake, so external holding mechanisms are required if the load must remain fixed when power is removed. A fitted shaft seal limits lubricant escape and prevents particle ingress along the journal, while the standard housing profile mates with existing MDD adapters. The rotor is limited to a single shaft extension, leaving side B free for tight installations or proximity sensors that require unobstructed clearance.
