Product Description:

The MAC021B-0-WS-2-E/032-A-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as a rotary actuator for industrial automation lines that still rely on analog velocity and position loops, translating commanded current into controlled shaft movement for pick-and-place modules, printing cylinders, or small feed axes. Its compact format suits machinery that uses established analog servo amplifiers instead of newer network-based motion platforms.

The motor uses a WS winding, and its coil resistance and inductance are matched to legacy analog drives so current regulators remain within a linear operating range. Its compact 021 frame size reduces the footprint when multiple axes are clustered on a single machine base. The power connection is made through a connector on side A, allowing cable routing to follow the motor flange without crossing adjacent devices. Heat is removed through natural convection, so no fan or liquid circuit is included and ambient airflow must carry away copper losses. For velocity verification, the back shaft carries tacho feedback, which supplies an analog speed signal for closed-loop operation in older drive amplifiers without requiring a digital encoder.

The motor uses B length, which provides a moderate stack depth that fits inside shallow enclosures while still leaving room for couplings. The motor has no blocking brake, so external clamps or drive torque must secure vertical loads when power is off. Because the unit is delivered as a motor for analog drives, its terminals, feedback scale, and insulation system are aligned with ±10 V control architectures rather than modern fieldbus networks. This arrangement supports integration with legacy motion systems that depend on analog command signals and direct speed feedback.
