Product Description:
The MAC093A-B-PS-3-C/110-B-0 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives that converts controller commands into finely regulated torque and speed for positioning tables, gantries, and material-handling axes. Frame size 093 and length code A provide a compact enclosure for installations with limited space. Radial surface cooling and an auxiliary blower maintain thermal stability, allowing the motor to sustain its rated output during continuous operation in automated equipment.
The integrated blower is mounted below the motor shaft, directing airflow across the stator housing to augment the standard radial surface cooling channels. The fan operates from a dedicated 115 V AC supply, eliminating the need for a separate low-voltage converter inside the cabinet. A centering diameter of 110 mm aligns the flange precisely on gearboxes or adapter plates, helping keep runout within servo tolerances. At its nominal speed of 3000 rpm, the rotor supports stable speed feedback to the analog drive through a tachogenerator located on the second shaft end. Power conductors exit through a connector on side B, simplifying cable routing when the motor is installed with its output shaft facing the machine. This connector position can also help keep the power cable clear of nearby couplings and moving components.
The motor has no blocking brake, so applications that require static load support must rely on an external clamping device or torque supplied by the drive. The stator winding designation PS indicates the copper fill, resistance, and inductance values used with compatible analog amplifiers in the MAC platform. Standard tacho quality provides a feedback gradient of 3 V/1000 rpm, giving the controller a linear voltage signal for speed regulation without digital conversion. The second shaft end accommodates the tachogenerator while leaving the primary shaft available for connection to the driven mechanism. This arrangement supports bidirectional operation and rapid reversals in medium-inertia positioning systems.
