Product Description:

The MDD071A-N-040-N2T-095PL2 is a servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it delivers precise closed-loop motion so that packaging stations, pick-and-place heads, or auxiliary spindles can follow programmed position and speed profiles in real time. Its synchronous design supports accurate speed regulation and repeatable positioning during dynamic motion.

This model produces a continuous standstill torque of 2.2 Nm, meaning the shaft can hold that load indefinitely without overheating when cooling conditions in the cabinet are met. During normal operation, it reaches a nominal speed of 4000 rpm. A blocking brake is integrated, and its holding torque is rated at 6.5 Nm, which helps stop vertical or suspended loads when the drive is disabled. Machine fitment is eased by the centering pilot diameter of 95 mm, which aligns the motor housing with bell housings or mounting plates. Position feedback is supplied through digital servo feedback (DSF), allowing the controller to read rotor position during each interpolation cycle for smooth commutation and error monitoring.

An integrated multi-turn absolute encoder tracks several mechanical revolutions without battery support, eliminating homing moves after power loss. The power and feedback plug face left in the terminal box, and the interface uses a rugged connector that locks with a quarter-turn motion. The motor uses a keyway shaft to transfer torque into standard couplings, while a shaft seal helps prevent coolant or dust from entering the front bearing. The motor size code of 071 corresponds to its diameter class, the length code A indicates the shortest rotor stack, and both housing and rotor balancing are standard. The unit has a single-ended shaft with no side B extension.
