Product Description:

The MDD071B-N-040-N2S-095GB2 is an AC synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is built for direct connection to digital drive controllers, converting commanded current into accurate rotary motion for packaging lines, pick-and-place stations, and small robotic axes. Permanent-magnet excitation, compact iron core geometry, and an aluminum frame allow the unit to fit inside crowded cabinets while still responding quickly to torque demands encountered in industrial automation.

The motor supplies a continuous stall torque of 4.4 Nm and can run steadily at a nominal speed of 4000 min⁻¹ before field-weakening becomes necessary. Precise mounting is aided by a centering diameter of 95 mm, and all power and feedback conductors exit on Side B for predictable cable routing. A blocking brake rated at 6.5 Nm locks vertical or suspended loads when power is removed. The rotor is balanced to the Standard class, the housing finish is Standard, and the motor is identified by size 071 with length code B. Because the series variant omits a side B shaft end, only the drive side is available for coupling.

Interface features round out the design. A keyed industrial Connector handles both power and feedback, and position data are transmitted through Digital servo feedback (DSF) for high-resolution closed-loop control. The front bearing region is protected by a With shaft seal configuration that keeps lubricant in and contaminants out. Motion is delivered through a Plain shaft that accepts clamp or collet couplings without introducing keyway imbalance. These connection, sealing, and feedback elements complement the mechanical and braking capabilities detailed above, giving system designers a compact motor that integrates cleanly into drive-based motion platforms.
