MDD041B-N-100-N2K-050GB0
The MDD041B-N-100-N2K-050GB0 is a servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it delivers high-speed rotary motion for compact automation axes, pick-and-place units, and other installations that require precise velocity regulation. It is intended for closed-loop motion systems that rely on motor feedback to maintain repeatable movement during rapid acceleration and deceleration. Its compact format suits applications where fast response and accurate positioning are needed in limited machine space.
The motor has a nominal speed of 10000 rpm, which is the highest continuous running velocity under rated conditions and supports fast indexing in light-duty stages. At standstill, it can produce 1.35 Nm of continuous torque, so static holding or low-speed feed duties remain stable without overheating. Accurate mechanical alignment is supported by a centering diameter of 50 mm, which matches standard mounting flanges and helps keep the rotor coaxial with the load. Dynamic balance is set to a standard class to help reduce vibration across the speed range. Both power and feedback leads exit on Side B, and the single plug-style connector keeps wiring compact. The unit is size 041 with length code B, and it has a plain shaft for couplings that do not use keys.
Position data are delivered by an integrated absolute encoder, while commutation and speed tracking are handled through resolver feedback. This arrangement provides absolute position after power-up without external sensors and supports stable control at low and high speed. Because the motor is supplied without a blocking brake, stopping torque must be provided by the drive or by machine mechanics when power is removed. A fitted shaft seal helps prevent lubricant migration and protects the internal bearings from splashes. This layout is suited to typical industrial use where reliable sealing and consistent feedback are required.
