MDD041A-N-100-N2G-050GB1
The MDD041A-N-100-N2G-050GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for installation in digital drive controller systems where rapid speed regulation and compact dimensions are required. The motor converts electrical energy from the drive into mechanical rotation so that automated axes, pick-and-place units, or light-duty spindles can be positioned with high repeatability. Its compact format is useful where installation space is limited and responsive axis motion is required. A standard housing and an integrated blocking brake allow the unit to be mounted directly into machinery without an added external holding device.
During continuous operation, the motor sustains a standstill torque of 0.64 Nm, allowing small workpieces or sensor stages to be driven without exceeding thermal limits. Its rated mechanical speed reaches 10000 rpm, which supports high linear feed rates when it is coupled to ball screws or belt transmissions. Power and feedback conductors exit on Side B, and the factory-installed connector simplifies wiring to the drive cabinet. Position and velocity data are returned through resolver feedback, allowing the controller to monitor rotor position for closed-loop operation. The motor uses length code A, which keeps installed depth low in the 041 frame.
The integrated brake delivers 1.2 Nm of static torque so vertical loads remain fixed when the drive is disabled. Mounting is guided by a centering pilot of 50 mm, which helps position the motor accurately on the machine interface. A plain shaft with a factory shaft seal helps limit lubricant escape and the entry of particulate matter. The compact 041 frame size keeps the housing small for tightly spaced machine assemblies. Rotor balancing is standard, which supports smooth rotation across the speed range.
