MDD041B-N-100-N2G-050GB1
The MDD041B-N-100-N2G-050GB1 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is used on coordinated motion axes where the encoder signal is processed directly by the drive. In industrial automation cells, the unit converts regulated current into rotary motion for compact positioning tasks in packaging, printing, and assembly equipment that require high speed and repeatable torque from a small frame. Its compact format makes it suitable for axes where installation space is limited but responsive motion is still required.
Its continuous stall torque is 1.35 Nm, so the shaft can support static loads without overheating while the controller maintains holding current. During accelerated duty, the rotor reaches a nominal speed of 10000 rpm, enabling rapid feed movements in lightweight gantries and other fast-travel mechanisms. An integrated blocking brake rated at 1.2 Nm secures vertical or suspended axes when power is removed. Accurate mounting is supported by a centering diameter of 50 mm, and all power and feedback connections are routed on side B of the housing to simplify cable routing in compact machine layouts.
The compact 041 frame size and length code B provide a longer active lamination stack without increasing the motor diameter. Position data is delivered through resolver feedback, which tolerates temperature changes well and helps the drive maintain stable commutation during changing loads. The motor uses a plain shaft for direct coupling, and the installed shaft seal helps limit dust and splashed coolant entry into the housing. The rotor is dynamically balanced to a standard grade to reduce vibration during high-speed operation, and the cast aluminum housing provides a rigid enclosure for the windings and bearing arrangement.
