Product Description:

The MDD041A-N-100-N2G-050PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it supplies torque and speed for precise industrial motion sequences common in assembly cells, electronic component insertion equipment, and small handling axes. Its compact format suits installations where mounting space is limited. It is especially suitable for compact machine sections that cycle frequently and need stable control at low load inertia.

Its mechanical interface begins with a centering diameter of 50 mm, providing a reference surface that aligns the motor flange with attached machine frames. At standstill the rotor can deliver 0.64 Nm continuously, allowing the axis to resist modest loads without overheating. During operation the shaft reaches a nominal speed of 10,000 rpm, which suits light, high-cycle positioning tasks. Power and feedback cables exit on side A of the housing, so cable routing and bend radii can be planned from that face. The built-in resolver feedback supplies rotor position signals to the drive, enabling closed-loop control throughout the speed range. The motor uses the 041 frame size with the short A length code, and its rotor is balanced to a standard grade to limit vibration during general-purpose operation.

The shaft features a keyway for positive torque transmission to couplings or pulleys, and it includes a shaft seal that helps block coolant or dust from entering the bearing cavity. Because the unit is supplied without a blocking brake, any static holding duty must be handled by the drive’s energized torque or an external mechanical stop. A standard housing encloses the stator laminations and permits natural convection cooling when mounted inside a control cabinet. The sealed shaft end also helps protect the front bearing area during routine machine operation. This arrangement is suited to compact servo axes that use direct couplings or small belt drives.
