MDD071A-N-060-N2T-095PA1
The MDD071A-N-060-N2T-095PA1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is designed for digital drive controllers and converts drive current into precise rotary motion for positioning tables, pick-and-place heads, and small tooling spindles in automated lines. The motor uses size 071 with the short A length code to minimize footprint, and its standard housing suits cabinet installation without extra protective enclosures. This combination makes it a practical choice for compact axes that need repeatable motion, fast response, and straightforward integration with closed-loop control hardware.
This model develops a continuous standstill torque of 2.2 Nm, giving steady holding force during low-speed interpolation and controlled dwell periods. Its rated operating speed reaches 6000 rpm, so high cycle rates can be achieved on lightly geared axes without sacrificing dynamic response. Mechanical centering on a 95 mm pilot diameter simplifies alignment to gearboxes or flanges, and standard dynamic balancing helps reduce vibration during operation. Power, brake, and feedback leads exit on side A, which supports one-direction cable routing in tight machine layouts. Position and revolution data are provided by an integrated multi-turn absolute encoder, allowing the drive to recover rotor angle after power loss and resume control with known position data.
To secure vertical loads when de-energized, the blocking brake applies 3.0 Nm of torque, and its release is commanded through the same connector used for phase conductors. Closed-loop control is handled with digital servo feedback (DSF), giving the drive high-resolution velocity and position signals for stable regulation at low and changing speeds. The single shaft end is machined with a keyway and fitted with a shaft seal to help keep lubricant inside the bearing chamber while protecting the shaft opening. A molded connector serves as the interface for power and signals. This arrangement keeps the connection area compact and supports orderly cable entry at the motor.
