MDD041A-N-100-N2K-050PB1
The MDD041A-N-100-N2K-050PB1 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion in automated assembly lines, pick-and-place gantries, and other closed-loop axes. Its compact 041 frame allows it to fit into machines where space is limited while still providing the rotational speed needed for high cycle rates.
The motor delivers a continuous standstill torque of 0.64 Nm, which is suitable for holding position while the shaft is stationary. During operation, it can reach a nominal speed of 10000 rpm, allowing fast indexing or spindle duties that benefit from high velocity. A blocking brake is integrated, and its holding torque is 1.2 Nm, so the shaft remains fixed after power is removed. Electrical and feedback connections emerge on Side B, and the 50 mm centering diameter simplifies coaxial mounting to gearboxes or couplings. Standard dynamic balancing reduces residual vibration, and the housing is the standard uncooled version. Motor size 041 with length code A keeps total mass low, and the shaft seal helps prevent lubricant leakage during extended duty cycles.
Signal integrity is maintained through the sealed connector that carries both power and feedback lines. Position data originate from an integrated absolute encoder, while servo loop velocity is derived from resolver feedback, allowing the drive controller to process both position and speed information in closed-loop operation. The output shaft uses a keyway profile for positive torque transmission, and it is supplied without an opposite-side extension to suit single-ended couplings. The standard shaft end mates directly with clamped hubs, which supports secure coupling in compact drive assemblies.
