MDD071B-N-040-N2T-095GR2
The MDD071B-N-040-N2T-095GR2 synchronous servo motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded current into closed-loop torque and speed for automated handling modules, packaging stations, and light-duty machining centers where repeatable axis motion is required. A blocking brake secures the shaft when power is removed, and the 071 frame with B length gives the motor a compact form that suits shallow machine layouts while still providing enough surface area for heat dissipation during continuous duty.
The unit reaches a nominal speed of 4000 rpm, allowing rapid indexing without overspeeding connected mechanics. It provides a continuous standstill torque of 4.4 Nm, so the motor can hold a steady load at zero speed without additional cooling. Installation is aided by a 95 mm pilot diameter on the flange for accurate centering. Power and feedback cables leave from the right side, and the motor uses a plug-in connector for electrical connection. The unventilated housing relies on surface convection for cooling, and standard dynamic balancing helps limit shaft vibration at rated speed.
Position data is provided by an integrated multi-turn absolute encoder with digital servo feedback, so the drive can monitor rotor position during moves and homing sequences without an external resolver. This feedback arrangement also gives the controller absolute position information after power-up, which supports precise motion control through repeated operating cycles. When the machine is idle, the holding brake supplies 6.5 Nm of torque to help prevent drift on vertical axes. The output uses a plain shaft with a shaft seal, which supports common clamp or collet couplings while helping keep lubricant away from the bearing area.
