Product Description:
The MDD071B-N-030-N2M-095PB1 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 supplies rotary motion to axes that need coordinated velocity and position control in automated production lines. A standard housing and standard dynamic balancing simplify mounting, while the integrated blocking brake secures the load when power is removed.
The motor delivers a continuous stall torque of 4.4 Nm, giving a reference for amplifier sizing and matching mechanical loads. Under rated operating conditions, the rotor reaches 3000 rpm, aligning with common machine tool spindle and feed rates. When the blocking brake is engaged, it can hold up to 3.0 Nm, preventing axis drift during power-off periods or emergency stops. Precision alignment on the machine frame is handled by a centering diameter of 95 mm. Power and feedback conductors exit on side B, a layout that eases cable routing when the opposite face is obstructed. A circular connector serves as the connection type, and motor length code B marks the mid-length stator option in this frame size. Housing, shaft end, and balancing are all standard versions for this motor configuration.
The motor uses a compact frame designated 071. Torque is transmitted through a shaft with a keyway, and a shaft seal keeps lubricants from migrating into the stator cavity. Rotor position is reported by an integrated multiturn absolute encoder, while the control loop relies on digital servo feedback (DSF) to maintain synchronization with the drive electronics. The absence of a secondary shaft end on side B reduces overhang, and the standard housing allows closed-coupled mounting in IP-rated enclosures without additional adapters or extension pieces.
