Product Description:

The MDD071C-N-040-N2T-095PA1 is a synchronous motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers and supplies controlled rotary power to axes in automated production cells, packaging lines, and material-handling systems. In servo applications, that controlled output helps the connected drive maintain accurate starts, stops, and speed changes. Its synchronous design supports responsive torque delivery during short cycle movements and positioning tasks.

The unit attains a nominal speed of 4000 rpm, supporting fast indexing cycles when paired with an appropriately rated drive. A continuous torque at standstill of 6.6 Nm lets the shaft hold static loads without overheating, while the integrated multiturn absolute encoder works with the drive to track position across power cycles. Mechanical alignment to gearboxes or mounting plates is aided by a 95 mm centering diameter, and vibration is limited by standard dynamic balancing. Power and feedback conductors exit on side A through a sealed connector interface, which can simplify cable routing in compact machine layouts. Motion data is transmitted via digital servo feedback (DSF), so high-resolution feedback reaches the controller without additional interface converters. Because the cable exit is grouped on one side, surrounding hardware can be arranged more neatly in narrow installations. A standard-profile housing allows convection cooling in tight machine frames.

The motor includes a blocking brake that produces 3.0 Nm of holding torque, enabling load retention during emergency stops or power loss. The brake can also help keep a vertical or inclined axis from drifting when power is removed. Shaft protection against dust and splash is provided by a shaft seal, and the single-ended shaft is finished with a keyway to secure couplings or pulleys. Frame designation 071 indicates the stator diameter, while length code C indicates the active stack height for this model. The drive-side shaft end is standard, and there is no extension on side B, which helps when space behind the motor is limited. That layout leaves more room for nearby machine structures and rear cable clearances.
