MDD071A-N-040-N2T-095GL1
The MDD071A-N-040-N2T-095GL1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, delivering closed-loop motion for positioning tasks on packaging lines, pick-and-place axes, and compact machine tools. By integrating the rotor, stator, feedback system, and brake into a single housing, the motor provides a space-efficient drive element for industrial automation where repeatable torque and speed are required.
The motor can develop a continuous standstill torque of 2.2 Nm, which indicates the sustained mechanical twisting force available for holding or slowly moving loads without thermal overload. During dynamic operation, it reaches a nominal speed of 4000 rpm, matching drive controllers that output high-frequency sinusoidal currents. A blocking brake supplies up to 3.0 Nm, so vertical or suspended axes remain stationary when power is off. A centering diameter of 95 mm supports repeatable alignment to gearboxes or flanges. All power and feedback connections exit on the left side through a sealed connector, which helps simplify cable routing in multi-axis cabinets. Standard balancing limits residual vibration, and the standard aluminum housing dissipates heat by natural convection. Size code 071 and length code A indicate the stator stack dimensions used in this motor frame.
An integrated multi-turn absolute encoder provides position data over multiple revolutions, while digital servo feedback (DSF) allows direct transmission to compatible Indramat drive controllers without additional converters. The motor uses a plain shaft machined to DIN tolerances, simplifying coupling to clamping hubs or pulleys. A factory-installed shaft seal protects the interior against coolant splash, and the shaft end is provided only on side A to keep the overall length compact. The connector interface also allows quick cable exchange when the motor is installed in tightly spaced machinery.
