Product Description:

The MAC071A-0-ES-4-C/095-B-0/W1620LV/S001 is an AC servo motor engineered by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It operates with analog drive controllers and supplies closed-loop rotary motion for positioning tables, pick-and-place heads, and similar axes in automated equipment. The unit converts commanded current into precise torque while providing tacho-derived speed feedback to the drive, allowing the controller to maintain steady velocity or follow reference profiles under varying loads. This arrangement suits machinery that needs repeatable motion with direct feedback handling in the connected amplifier.

The motor’s mechanical interface uses a centering diameter of 95 mm, supporting direct attachment to gearboxes or machine frames without additional adapters. Its rotor is designed for a nominal speed of 4000 rpm, enabling fast indexing where cycle time is critical. Heat is removed by natural convection, so adequate air space around the housing is required instead of forced ventilation. Integrated tacho electronics generate 1.5 V/1000 rpm, and the feedback channel can use tacho feedback, an incremental encoder, or an absolute encoder depending on the control requirement. The A length code balances shaft overhang and inertia, while standard tacho quality supports general-purpose accuracy. This combination allows the motor to fit compact machine sections as long as airflow around the housing is not obstructed.

For shaft coupling, the output end uses a DIN 6885 keyway, giving positive torque transmission without slip. The motor has a frame size of 071, which aligns with the torque class used for this model. Power conductors leave through a connector on side B, simplifying right-angle cable routing inside cabinets where rear clearance is limited. The armature winding marked ES sets the voltage constant so the drive can apply rated current across the speed range. Because no blocking brake is fitted, any vertical load must be held by external means. The cable outlet orientation can also help when nearby guards, panels, or machine members restrict routing space around the motor body.
