Product Description:

The MDD071C-N-040-N2T-095PR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power from the drive into precisely regulated shaft rotation for indexing tables, pick-and-place axes, and similar automation points. The unit uses a standard balancing class and a single shaft end on side A only, which helps it fit compact machine frames that do not allow space for a rear shaft extension. This layout also keeps the motor suited to direct coupling arrangements where motion must remain accurate during repeated start and stop cycles.

Rated for a nominal speed of 4000 rpm, this size 071 motor with length code C maintains positional stability with 6.6 Nm of continuous standstill torque, while a blocking brake provides 6.5 Nm of holding torque after power is removed. Mechanical alignment is simplified by its 95 mm centering diameter, which seats the motor accurately in matching machine flanges. Power and feedback connectors are placed on the right side, helping route cables away from nearby tooling or guards. The motor uses a single circular connector for both power and signal conductors, which reduces connector count and helps keep the installation compact.

Position data comes from an onboard integrated multiturn absolute encoder that works with the drive’s digital servo feedback channel to report absolute rotor position over multiple revolutions. Torque is transmitted through a keyway shaft, and a fitted shaft seal helps keep dust and oil away from the bearing area. The motor uses length code C, giving it a mid-range housing depth within the 071 frame size. Its standard housing supports convection cooling during normal operation, and the feedback system allows the drive to retain accurate position information after power interruptions.
