Product Description:

Bosch Rexroth Indramat's MAC071C-0-NS-4-C/095-B-1/WI520LV/S001 belongs to the MAC AC Servo Motors series and is supplied as a motor for analog drives. It converts commanded current into proportional torque for indexing tables, pick-and-place arms, and packaging axes that need consistent closed-loop velocity. A compact housing combines the permanent-magnet rotor and feedback devices, allowing the unit to fit multi-axis assemblies while maintaining accurate motion control. That arrangement also helps the connected drive stabilize speed during repeated starts, stops, and short positioning moves.

With a frame size of 071, the motor occupies a moderate footprint suitable for compact axis modules. It maintains a rated speed of 3000 rpm, allowing direct coupling to gear stages or belt transmissions without overspeed concerns. Shaft alignment is assisted by a 95 mm centering diameter, which matches common machine mounting interfaces and helps reduce radial runout. Heat generated in the stator is removed through natural convection, so no auxiliary fan or liquid circuit is required. Because cooling is passive, surrounding installation space should remain open enough for heat to leave the housing. During power-off or an emergency stop, the integrated blocking brake applies 3 Nm of holding torque to help prevent load drift on lightly loaded vertical axes.

The electrical winding uses code NS, pairing the motor with analog drives that provide the current characteristics intended for this resistance and inductance profile. Power conductors exit through a connector on side B, which can simplify cable routing when the motor is mounted with the shaft facing forward. Output torque is transmitted through a DIN 6885 keyway, allowing keyed hubs to lock axially along the 16 mm shaft without backlash. Speed feedback is supplied by an incremental encoder mounted in the standard housing, and its companion tacho generator produces 3 V/1000 rpm for velocity loops that use proportional voltage feedback. The encoder and tacho arrangement lets the connected drive receive both position and speed information from the same motor assembly. The C mechanical length leaves room for the feedback package and brake without pushing the motor beyond the intended envelope.
