Product Description:

The MAC112C-0-ED-2-C/130-A-1/S05 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drive systems, it converts electrical energy into controlled mechanical rotation for positioning and velocity duties in automated machinery. By integrating position feedback and a blocking brake, the unit supports precise axis control and safe holding during power-off conditions within packaging cells, transfer stations, and similar equipment.

Key mechanical data begin with a centering diameter of 130 mm that aligns the flange to gearboxes and keeps radial run-out low. The built-in blocking brake delivers 45 Nm of static torque so the load stays fixed when the drive is disabled. Thermal management relies on Natural convection; heat leaves the housing without fans, reducing maintenance. Rotor position is monitored through a configuration with tachofeedback that supplies a proportional voltage to the analog controller. The windings follow code ED, giving electrical constants matched to the MAC drive family. Continuous operation at a nominal speed of 3000 min⁻¹ permits direct coupling to ball screws or belts without extra reduction stages.

Electrical integration is simplified by the power connector mounted on side A, so cabling routes toward the drive cabinet without crossing moving parts. The stator package follows the C length designation, balancing continuous torque capability against overall footprint for medium-inertia axes. A frame size of 112 defines the outer diameter and shaft height, making the motor interchangeable with other units of the same size class. The tachogenerator outputs 3 V per 1000 min⁻¹, providing a linear speed signal that the analog loop uses for regulation. Coupled with passive cooling and the matched winding, these mechanical and electrical attributes create a servo element that supports precise positioning while keeping maintenance demands low.
