Product Description:

The MAC021A-0-YS-2-E/032-A-0/S001 is a compact servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for integration into analog control loops where voltage commands are converted into proportional shaft torque and speed. Within automated machinery, the unit drives light-to-medium load axes by using integrated speed feedback and without auxiliary cooling devices. Its mechanical outline supports direct flange mounting, so the motor can couple to gearboxes, timing belts, or lead-screw assemblies used in packaging, printing, and material-handling installations. The compact housing also helps when available motor space is limited near slides, feeders, and small transfer mechanisms.

The frame designation 021 sets a small stator diameter that lowers inertia and favors rapid acceleration. Stack length code A provides enough active iron to maintain continuous torque while keeping the housing short. Thermal energy leaves the enclosure by natural convection, so open space around the motor body is needed for heat dissipation during operation. Rotational velocity is sensed through integrated tachometer feedback, which generates a proportional voltage that analog regulators use for closed-loop speed control. Power conductors terminate in a sealed circular connector, which keeps the connection layout compact and separates high-current lines from signal wiring.

The supply interface uses a connector on side A, allowing fixed cable routing along the motor flank and reducing harness movement near the housing. The motor has no blocking brake, which reduces rotor inertia and leaves holding torque to the external drive or machine mechanism when the axis stops. Delivered as a motor for analog drives, the unit pairs with amplifiers that use the internal speed signal for stable velocity regulation. This arrangement suits compact axes that prioritize smooth speed control and a simple motor package.
