Product Description:

The MAC112C-0-ED-2-C/130A-1/505 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive current into controlled shaft torque and speed for positioning tasks on machine tools, packaging lines, and transfer equipment. The motor integrates with analog velocity or position controllers common in legacy automation, allowing stable feedback-based regulation without digital fieldbus hardware.

Mechanical dimensions begin with a centering diameter of 130 mm, allowing direct flange mounting onto gearboxes or machine frames without additional adapter rings. The rotor is designed for a nominal speed of 3000 rpm; this base speed matches conventional drive applications when regulated by an analog controller. Heat is removed through natural convection, so the housing relies on surface area and ambient airflow rather than forced fans. Frame designation 112 denotes the stator size and aligns the shaft height and bolt pattern with the MAC family standard. Electrical behavior is indicated by winding code ED, which corresponds to the phase resistance, inductance, and rated current values expected by compatible analog drives.

Velocity information is generated internally, and the motor is supplied with tacho feedback, producing a proportional voltage signal that closes the analog speed loop. The tachogenerator delivers 3 V/1000 rpm, so a controller receives 9 V when the shaft reaches 3000 rpm, enabling straightforward scaling of gain components. Stack length index C identifies the magnetic core depth that sets continuous torque without altering the 112 mm frame. Tachometer assembly quality is graded as Standard, providing repeatable output characteristics for general-purpose machining axes and conveyor sections that do not require laboratory-grade velocity linearity.
