MDD041C-N-100-N2G-050PB0
The MDD041C-N-100-N2G-050PB0 is a motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as the rotary actuator in compact automation axes. It supplies precise speed and torque so a drive controller can execute positioning, indexing, or coordinated motion tasks on packaging, printing, or small handling equipment.
This model reaches a nominal operating speed of 10000 rpm, allowing high surface velocities on lightweight mechanisms. At standstill it can deliver 2.05 Nm continuously, which is the stall load the drive can hold without thermal overload. The rotor uses standard balancing, and the flange includes a centering diameter of 50 mm for accurate location against gearboxes or mounting plates. Power and feedback plugs are oriented on Side B, which helps cable routing inside narrow cabinets. A sealed Connector interface is used instead of flying leads, which helps maintain ingress protection. The motor has size 041 and length code C, which correspond to the stator diameter and active stack used in this model.
Feedback signals are produced by an integrated resolver feedback unit, giving analog sine-cosine data for high-resolution interpolation in the controller. For holding duties, the unit is supplied without a blocking brake, so any static load must be secured electrically or with an external clamp. The shaft follows the DIN profile and is described here simply as a keyway, ensuring positive torque transfer to couplings. A factory-installed shaft seal prevents oil or coolant from migrating along the shaft bore into the stator cavity, and the housing uses the standard non-cooled design for normal ambient conditions. The shaft end is single-sided, so there is no secondary projection on side B to interfere with tight machine frames.
