Product Description:

The MDD071B-N-030-N2S-095PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into controlled rotary motion for packaging cells, handling gantries, and other automated stations. Size 071 construction with length code B gives a mid-range envelope, while the standard housing and standard balancing support direct mounting in typical factory conditions. Its synchronous design supports responsive acceleration and repeatable positioning in indexing, transfer, and feed applications.

At a continuous standstill rating of 4.4 Nm, the motor can resist load torque indefinitely without exceeding its thermal limit. During motion, it reaches a nominal speed of 3000 rpm, providing a predictable velocity point for the paired drive. A centering pilot of 95 mm maintains concentricity between the motor flange and adjoining mechanics, which helps reduce bearing wear and coupling misalignment. Field wiring exits on Side B, and a single circular connector carries both power and signal conductors. This arrangement keeps external connections compact and reduces the number of separate cable entry points at the motor.

An internal blocking brake supplies 3.0 Nm of static torque to lock the shaft when power is lost or when the axis is brought to a stop. Position information is returned through digital servo feedback, allowing stable closed-loop control with accurate speed and position response. The driven interface uses a keyway so couplings can transfer torque without slip, and a shaft seal helps protect the interior from coolant spray and fine dust. Because only the drive-side shaft is present, the opposite face remains open for cable exit and air circulation. The brake and sealed output end are useful on axes that stop frequently and then restart under closed-loop control.
