Product Description:

The MDD071A-N-040-N2M-095PB0 is a synchronous servo motor built by Bosch Rexroth Indramat as a member of the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers and converts electrical power from the associated inverter into mechanical rotation for positioning tables, feeders, and other precision axes in industrial automation cells. In automated equipment, the motor serves as the rotary output element that responds to drive commands during acceleration, positioning, and reversal. This makes it suitable for applications that require controlled motion and repeatable axis response.

At stall, the motor develops a continuous torque of 2.2 Nm, allowing static holding of moderate loads without overheating. During motion, the rotor can reach a nominal speed of 4000 rpm while remaining within normal thermal and voltage limits. Accurate centering against the machine flange is achieved through a 95 mm centering diameter. Cabling is routed toward the rear because the power and feedback connectors are positioned on Side B. For position feedback, the unit incorporates an Integrated multiturn absolute encoder, so the drive can retain absolute shaft position after power loss. This arrangement supports orderly cable routing when the motor is installed near moving machine components.

The control loop receives high-resolution position data through Digital servo feedback (DSF), supporting tight velocity and torque regulation. Motion is transmitted through a shaft machined with a keyway, which provides a positive mechanical connection to couplings or pulleys. The front bearing region is supplied with a shaft seal to help limit contamination ingress. The motor is supplied without a blocking brake, so holding force must be provided by an external device when the axis is stopped. Mechanical balancing is performed to the standard grade to reduce residual vibration during normal operation. The A length code keeps the housing compact, which helps where installation depth is limited.
