Product Description:

The MDD041B-N-100-N2G-050GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is used with digital drive controllers and converts inverter current into precise rotary motion for compact pick-and-place units, light conveyor stations, and other small automation axes. The motor is well suited to applications that need quick acceleration, steady speed control, and repeatable positioning in a limited installation space. Because it is a synchronous design, it works with the drive to maintain commanded speed and position with high accuracy during continuous machine operation.

This unit uses frame code 041 with length designation B, giving it a compact housing for restricted mounting spaces. A centering diameter of 50 mm keeps the motor aligned on the machine flange, and all plugs are placed on Side A so cables leave in one direction. This layout helps keep cable routing orderly where surrounding machine parts leave little clearance around the motor body. The rotor reaches a nominal speed of 10,000 rpm, which supports short cycle times on light automation axes. At standstill, it provides a continuous torque of 1.35 Nm, and the plain shaft is intended for friction-fit couplings rather than keyed hubs.

A blocking brake with 1.2 Nm of holding torque secures the axis when power is removed. The integrated shaft seal helps keep dust and lubricants away from the bearing area, which supports cleaner operation in enclosed machinery. Position data is returned through resolver feedback, providing analog sine-cosine signals for speed and angle control. Resolver-based feedback is useful where stable signal transmission is needed under vibration or electrical noise. Power and feedback connections use circular connectors, and single-plane balancing helps keep rotation smooth across the usable speed range.
