Product Description:

The MDD071A-N-060-N2T-095PB0 is a motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a permanent-magnet AC servo unit, it supplies rapid closed-loop positioning to handling, packaging, and machine-tool axes. Integrated with Rexroth drive modules, the motor converts commanded current into synchronized rotational motion, acting as a compact actuation element for automated systems. This arrangement supports accurate speed and position control during repeated start-stop cycles in automated equipment.

The unit operates at a nominal speed of 6000 rpm, enabling high-cycle duty when coupled to lightweight loads. At standstill, it maintains 2.2 Nm of continuous torque so fixtures remain stable during dwell periods. Concentricity during mounting is set by a 95 mm centering diameter, and rotor mass is factory balanced to the Standard grade to minimize vibration over the full speed range. Power and feedback conductors exit on side B through a sealed connector interface. Position information is generated by an integrated multi-turn absolute encoder, allowing the drive to recover rotor angle after a power cycle without external homing.

Feedback signals reach the controller through Digital servo feedback (DSF), supporting high-resolution velocity and position loops. The ground shaft uses a keyway profile for positive torque transmission, and contamination ingress is limited by delivery with a shaft seal around the output journal. Because the motor is shipped without a blocking brake, external holding devices are required when static torque alone is insufficient. The housing follows the series' standard construction, and Motor Length Code A keeps overall mass low while preserving thermal paths. The motor has frame designation 071, which corresponds to the stator and flange size.
