MDD041B-N-100-N2G-050FB0
The MDD041B-N-100-N2G-050FB0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the device converts electrical energy into tightly regulated rotary motion for pick-and-place arms, feed drives, and small spindle stations in automated lines. Its frame size 041 and length code B keep the footprint compact, while the standard housing allows direct mounting to machine frames or in electrical cabinets with limited clearance. This layout suits axes that need responsive motion without taking up much installation space.
Its mechanical interface uses a centering diameter of 50 mm, which aligns the flange precisely to the mating surface and helps keep radial runout low. Power and feedback plugs are located on Side B, so cabling exits opposite the working shaft and stays clear of nearby gearboxes or pulleys. Position data is generated by resolver feedback, enabling accurate rotor angle detection at high speeds. Under continuous stall, the motor can produce 1.35 Nm, which is suitable for holding light loads without additional gearing. It can run at a nominal speed of 10000 rpm, supporting high-cycle processes that require rapid acceleration and short motion sequences. A detachable connector keeps the electrical connection separate from the motor body and simplifies cable routing.
The rotor is balanced to standard balancing grade, which helps reduce vibration when the motor is coupled directly to precision mechanisms. The motor uses a single output side with a plain shaft, while the opposite end is closed so there is no second shaft extension to affect mounting space. It is supplied without a blocking brake, so any static holding force must be provided by the drive or by an external clamp. The front bearing area is without a shaft seal, which makes the motor suitable for dry environments or enclosed spaces where contaminants are controlled.
