Product Description:

The MAC112C-0-ED-3-C/130-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This model is intended for analog drive systems, where the controller issues proportional current and velocity signals instead of fully digital fieldbus commands. In industrial automation, the motor delivers closed-loop rotary motion for positioning axes, pick-and-place heads, and material-handling stations. It converts electrical setpoints into stable mechanical movement with repeatable speed and position control during continuous machine operation. That makes it suitable for packaging lines, indexing tables, and transfer systems that depend on responsive analog servo control.

The motor has a centering diameter of 130 mm, which aligns the housing with the machine frame and helps maintain concentricity. Heat is removed through natural convection, so the mounting area must allow unobstructed airflow around the housing. Under rated excitation, the rotor reaches 3000 rpm, which suits mid-range dynamic response in analog servo applications. The integrated tacho generator outputs 3 V/1000 rpm, and this signal feeds the analog velocity loop for real-time feedback. The analog feedback path helps the connected amplifier correct speed deviations caused by changing load conditions. Power is routed through a connector on side B, permitting cable exit toward the non-drive end of a typical cabinet layout.

The motor has size 112 and length C, giving a balance between inertia and continuous torque for medium payloads. The stator uses an ED winding, which lets the drive amplifier supply the required current without saturating the magnetic circuit. The unit has no blocking brake, so any vertical axis must rely on external mechanical holding if power is lost. For axes that must hold position at standstill, a separate holding device or controlled motor torque is required. A secondary shaft end supports the tacho feedback assembly, and the feedback arrangement can also serve as a reference for an external encoder when higher resolution is required.
