Product Description:
The MAC090C-0-PD-3-C-110-B-1-S005 is a servo unit from the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. Classified as a motor for analog drives, it is used in positioning axes where torque and velocity are commanded by voltage signals rather than digital buses. Within industrial automation, the model converts drive current into controlled mechanical rotation for tooling, handling, or packaging machinery. It can also serve feed axes, indexing mechanisms, and other machine motions that require predictable response during repeated operating cycles.
Mechanically, the motor seats against a faceplate that incorporates a centering spigot measuring 110 mm in diameter, allowing coaxial alignment with gearboxes or direct-drive flanges. This centering feature helps maintain shaft alignment and reduces coupling stress during installation. Heat generated by the stator is removed through natural convection, so supplementary fans or liquid circuits are unnecessary when the housing is left unobstructed. During operation, the rotor stabilizes at a nominal speed of 1500 rpm, which fits moderate-speed axis applications. Mains conductors are attached through a right-angle connector on side B, which simplifies cable routing when several motors share a cabinet wall. The motor uses a PD winding, so the drive amplifier can match its electrical characteristics to the required torque response.
Position and holding duties are supported by a standard blocking brake that clamps the shaft when control power drops, helping prevent back-driving on vertical axes. Velocity feedback is supplied by a tachogenerator mounted on a second shaft journal; this arrangement is identified as tacho feedback and a second shaft end and feeds the drive with a proportional signal of 3 V/1000 rpm. The motor uses standard tacho quality, so ripple and linearity remain within the range expected by analog regulators. This arrangement allows the paired amplifier to monitor motor speed continuously and correct deviations during load changes.
