Product Description:

The MDD041B-N-100-N2G-050FA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated electrical power into precise rotary motion for positioning and velocity loops. Its compact frame size 041 and B housing length suit space-limited axes on packaging machines, pick-and-place heads, and light conveyors that require high speed with moderate torque. In servo systems, the motor works with feedback and current regulation so commanded speed changes and positioning moves can be followed with stable response.

This model uses a centering pilot of 50 mm to seat the flange concentrically against the mounting surface and reduce runout during high-speed operation. Power and feedback conductors exit on side A, which can simplify cable routing when the motor faces the load. A single multipole connector carries phase, sensor, and ground contacts in one interface. This combined connection reduces the number of separate cable entry points at the motor housing. At standstill, the electromagnetic design can deliver 1.35 Nm continuously, and under rated conditions the rotor can attain 10,000 rpm for short cycle times on fast-moving equipment.

The motor is supplied without a blocking brake, so vertical loads must be held by external clamping or drive-applied torque when power is removed. Rotor balancing is standard, and the housing dissipates heat by natural convection. Position information is returned through resolver feedback, which provides analog sine-cosine signals with good resistance to electrical noise. The output uses a plain shaft with no keyway, and the unit is supplied without a shaft seal, so the surrounding machine design must prevent fluid ingress. Because there is no shaft seal, the motor is better suited to clean, dry mounting areas, and the shaft is present only on the drive side with no extension on side B.
