Product Description:

Bosch Rexroth Indramat manufactures the MAC093A-0-PS-4-C/110-B-1/WI521LX as part of its MAC AC Servo Motors series. This unit is a motor for analog drives that converts drive controller output into precise mechanical motion for industrial automation tasks such as coordinated material transport and indexing. By pairing tachometer and encoder feedback with closed-loop control, it delivers repeatable velocity and position profiles demanded by automated packaging, printing, and assembly equipment.

The motor aligns to adjoining mechanics through a centering shoulder that measures 110 mm in diameter, ensuring concentric mounting on gearboxes or brackets. Heat generated in the stator is removed by natural convection, so no forced-air or liquid auxiliaries are required, which simplifies cabinet layout. Its shaft is designed to reach a nominal speed of 3000 min⁻¹, allowing the drive to support mid-range line rates without overspeeding the winding. An internal tachogenerator outputs 3 V/1000 min⁻¹; this voltage is proportional to shaft speed and is used by older analog regulators for velocity feedback. Winding code PS identifies the resistance, inductance, and current ratings that must match the connected amplifier. Motor length code A and the standard tacho quality are part of the stated motor configuration.

The motor has size 093, giving a frame diameter that balances torque capacity against footprint for medium-duty axes. A standard blocking brake is integrated to hold position when power is removed, preventing load drift on vertical or indexing stations. Power enters through a connector on side B, allowing cable routing opposite the drive shaft to minimize interference with couplings. Rotor position is reported by a incremental encoder mounted in the standard housing, and the feedback configuration can also accept an absolute encoder when required by the control architecture. This arrangement supports position monitoring and stable motion control in analog drive systems.
