MDD071A-N-040-N2T-095GR0
The MDD071A-N-040-N2T-095GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical energy from an inverter into precise rotary motion for positioning tables, handling modules, and packaging axes. The compact 071 frame and A-length stator keep the body short, while standard dynamic balancing helps reduce vibration during operation. This layout suits closed-loop automation tasks where stable response is needed through frequent starts, stops, and short positioning moves.
The unit delivers a continuous standstill torque of 2.2 Nm, allowing it to hold moderate loads while stationary. During operation, it reaches a nominal speed of 4000 rpm, giving drive systems a wide velocity range for rapid indexing. A centering diameter of 95 mm sets the locating register on the mounting face, which helps align the motor with gearboxes or machine plates. Power and feedback leads exit on the right side through a keyed connector, which helps route cables in tight enclosures and keeps the connection secure during motion. The standard housing protects the windings, and the plain shaft runs smoothly in compact machine sections.
An onboard integrated multiturn absolute encoder supplies position data to the drive through digital servo feedback, allowing accurate control of velocity, position, and acceleration. The feedback system also lets the controller recognize shaft position immediately after power-up, which supports repeatable motion without a separate reference routine. The motor is supplied without a blocking brake, so external holding force is required whenever a vertical load must remain fixed after power is removed. A fitted shaft seal protects the plain shaft against fluid splash and dust, helping preserve the bearing area during normal service. The standard shaft end on side A and the absence of a side B extension keep the package short for closely spaced multi-axis installations.
