MDD041B-N-100-N2G-050FA0
The MDD041B-N-100-N2G-050FA0 is a compact AC servo unit from Bosch Rexroth Indramat that belongs to the MDD Synchronous Motors series. Built as a motor for digital drive controllers, it converts commanded electrical input into controlled rotary motion for positioning and speed-regulated axes in compact automation equipment. The motor uses a standard housing and follows the 041 frame size with the B-length code, giving a short axial dimension that suits installations with limited mounting depth. Standard rotor balancing minimizes vibration across the speed range, while the plain single-ended shaft fits directly to couplings or pulleys in tight automation spaces.
The rotor can supply a continuous standstill torque of 1.35 Nm, which is available for holding or slow-speed indexing without overheating. Peak mechanical speed reaches 10000 rpm, allowing rapid point-to-point moves when paired with high-bandwidth drives. A 50 mm centering diameter on the flange helps align the motor with gearboxes or mounting plates during installation. Positional data is returned through resolver feedback, providing noise-resistant analog signals for commutation and closed-loop control. This feedback method supports stable speed regulation and consistent position tracking during repeated motion cycles.
Cabling exits on Side A through a keyed industrial connector, so power and feedback can be routed along the machine frame without sharp bends. The motor is supplied without a blocking brake, so applications that need holding torque at standstill must provide it through the drive or external mechanics. The shaft interface uses a plain shaft and is delivered without a shaft seal, making it suitable for clean, dry environments where low drag is preferred. A standard shaft end on the drive side and no auxiliary shaft on side B reduce overhang length and simplify coupling. This arrangement keeps the mechanical interface straightforward for direct connection to driven machine elements.
