MAC093C-2-KS-4-C/110-A-1/DI520LB/S001 by Bosch Rexroth Indramat

The MAC093C-2-KS-4-C/110-A-1/DI520LB/S001 servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is a motor for analog drives that provides closed-loop speed and position control in industrial automation systems such as machine tools and handling modules. The motor uses frame size 093 with C length, and the KS winding code matches drive units that can supply the required current profile. A standard blocking brake is included for power-off holding, and axial surface cooling is assisted by an external 115 V AC blower mounted on the housing.

During installation, the 110 mm centering flange locates the motor precisely on the machine face. With axial cooling active, it can produce 19.5 Nm of continuous standstill torque while drawing 22 A. Rated shaft speed is 2000 rpm, and short demand peaks are tolerated up to 110 A. The electromagnetic conversion ratio of 0.910 Nm/A gives a consistent relationship between current and torque output. A winding resistance of 0.433 ? limits copper loss, and the 50-minute thermal time constant indicates how quickly heat rises and falls in the winding. Operation is permitted up to 1000 m altitude, and supply cables connect through a connector on side A of the stator housing.

In dynamic cycles, the rotor carries 0.0042 kg·m² of inertia, which supports controlled acceleration without making the motor overly sensitive to load changes. Total motor mass is 22.0 kg, which helps the assembly resist vibration during normal machine operation. Position data comes from an incremental encoder mounted on shock-damped supports, and the integrated tacho provides 3 V at 1000 rpm for speed feedback. Phase inductance of 7.0 mH helps smooth current transients from the amplifier and supports stable current regulation. Housing seals rated IP65 protect the interior from dust and water jets, allowing use in machining environments where contamination and coolant splash are common.
