Product Description:

The MDD071A-N-040-N2T-095GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, it converts regulated current into rotation so automated stations can hold position, index, or follow precise speed profiles. This motor type is well suited to feed axes, indexing tables, and compact handling modules that require repeatable motion through frequent start-stop cycles. The motor is supplied in a standard housing and uses connector-based power and encoder connections for compact installation. It also uses standard balancing and the short A housing length, which help it fit tightly spaced machine layouts without adding unnecessary mass.

Its continuous standstill torque reaches 2.2 Nm, allowing the axis to support load without motion under closed-loop current control. During operation, the rotor reaches a nominal speed of 4000 rpm, which suits high-speed pick-and-place tasks or light spindle duty. An internal blocking brake provides 6.5 Nm of static holding torque when power is removed, which helps keep a vertical or suspended axis from drifting at rest. Mechanical alignment is set by the 95 mm centering diameter, and feedback is returned through digital servo feedback (DSF) for real-time position verification. The digital feedback channel lets the drive monitor rotor position and speed during commanded motion.

All external cabling exits on the right side of the stator, which can simplify routing in compact control cabinets or machine frames with limited side clearance. Position and revolution data are generated by the integrated multiturn absolute encoder, eliminating the need for homing cycles after shutdowns and preserving position information across power loss. Within the MDD frame, size code 071 sets the flange and mounting pattern, and a shaft seal protects the plain output shaft from airborne coolant or dust. The motor has a plain shaft with no side-B extension, which suits applications that couple through collets or friction hubs instead of keyed interfaces.
