MDD071B-N-030-N2S-095PR1
The MDD071B-N-030-N2S-095PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical power into regulated rotary motion for positioning and speed-controlled axes in automated machinery. The housing, shaft end, and balancing follow the standard pattern used for this motor line, while a factory-installed blocking brake holds the axis securely when the drive is de-energized. This arrangement suits machine axes that need precise movement during operation and reliable holding at standstill.
A centering pilot of 95 mm keeps the flange concentric with adjacent mechanics, which helps reduce runout during high-speed operation. All power and feedback conductors exit on the right side through a single industrial connector, an arrangement that simplifies cable routing and strain relief. Under continuous stall conditions, the motor develops 4.4 Nm of torque, allowing it to support static loads until motion commands resume. During motion, closed-loop regulation maintains a top speed of 3000 rpm, which matches many pick-and-place and feed-axis applications without exceeding the thermal capacity of the winding.
The built-in brake supplies 3.0 Nm of holding torque, so vertical or suspended loads remain stationary after power loss. Rotary position data is returned through digital servo feedback, enabling the drive controller to correct positional error with high accuracy. Size code 071 identifies the stator diameter used for this motor frame. The output uses a keyway shaft, which transmits torque without slip and works with the shaft seal to help keep lubricants inside the gearbox. The B-length stator and standard housing keep the motor compact for medium-inertia loads.
