Product Description:

The MAC021A-0-YS-3-E/032-A-0 is a compact drive motor manufactured by Bosch Rexroth Indramat and placed in the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts command voltages from legacy controllers into precise shaft rotation for pick-and-place assemblies, small conveyor sections, and auxiliary tool axes within automated cells. Its mechanical profile and electrical interface let machine builders integrate dependable closed-loop motion without the higher bandwidth demands of digital fieldbuses. The compact format also fits installations where brackets, slides, and other moving elements leave little room around the axis. It is well suited to production equipment that still uses established analog motion control.

Heat dissipation is handled through natural convection, so the housing should be mounted where ambient airflow can move freely because no fan or liquid circuit is included. Frame designation 021 indicates the stator diameter and the torque range supported by the motor. Stack length code A marks the shortest magnetic core used in this family, which helps keep mass and inertia low for fast acceleration. The main power leads exit through a compact connector on side A, allowing parallel cabling when multiple axes are lined up on a common plate and keeping the cable path clear of the mounting area. This side-exit arrangement also reduces cable crowding when several motors are mounted close together on narrow machine frames.

For installations that need mechanical holding during power loss, the motor has no blocking brake, so any required clamping must be provided externally. Its absence helps keep rotor inertia low and supports quick response during speed changes. The feedback package includes tacho feedback for speed monitoring, and a second shaft end allows an added encoder, belt pulley, or handwheel to be attached without changing the basic motor layout. That arrangement can support added mechanical devices without requiring a different housing style. Its voltage constants and signal levels align with classical ±10 V amplifiers, which helps the unit fit into existing control layouts.
