Product Description:

The Bosch Rexroth Indramat MDD071C-N-040-N21-095PB1 is a synchronous servo motor in the MDD Synchronous Motors series. It is intended for installation in digital drive controller systems, where it converts commanded current into mechanical motion for positioning tasks in automated machinery. The standard housing and integrated blocking brake make it suitable for axes that must hold a load when power is removed. Its connection layout also helps keep motor power and feedback wiring organized in compact machine assemblies.

During steady-state operation, the motor can deliver 6.6 Nm of continuous torque at standstill, providing sufficient holding force for precision feed axes without thermal overload. Its rated mechanical speed reaches 4000 rpm, allowing direct coupling to ball screws or belt transmissions without additional gearing. A centering shoulder of 95 mm supports repeatable alignment on machine frames, and all power and feedback leads exit on side B, which can simplify cable routing when the drive is mounted toward the rear of the cabinet. Electrical termination is completed through a keyed connector, supporting correct phase orientation and secure installation. The rotor is factory balanced to the standard grade, and the C length code indicates the stack height used for this motor size.

The embedded blocking brake supplies 3.0 Nm of static holding torque, helping prevent axis drift when power is cut during tool changes or emergency stops. With a frame designation of 071, the unit fits compact gantry or pick-and-place layouts where available space is limited. A fitted shaft seal protects the front bearing against coolant spray, while the machined keyway on the output shaft transmits torque to pulleys or couplings without slip. The motor uses a standard housing with a single-ended shaft for common industrial mounting arrangements.
