Product Description:

The MAC112C-0-HD-3-C/130-B-0/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, the motor converts electrical commands into controlled mechanical rotation for indexing tables, gantries, print mechanisms, and other automated equipment. Its internal tachogenerator supplies real-time speed data so the associated drive can maintain a stable feedback loop without requiring an external encoder. This arrangement supports precise positioning and repeatable cycle times during industrial operation.

The unit has a frame size of 112, providing a stator diameter that fits midrange machine envelopes while supporting high torque density. Winding code HD identifies the electrical configuration used with compatible analog amplifiers that supply higher current at moderate voltages. At its nominal speed of 2000 rpm, the rotor delivers rated output while the tachogenerator maintains a proportional feedback voltage. Heat produced during continuous operation is removed through natural convection, eliminating the need for an external blower or coolant plumbing. Precise shaft alignment during installation is supported by a centering flange with a diameter of 130 mm. The motor has a C-length mechanical stack that balances rotor inertia and continuous torque for general-purpose motion tasks.

The motor has no holding brake, so a vertical axis must be secured through drive-applied torque or an external clamp when power is removed. Power conductors enter through a connector on side B, keeping the wiring path clear of the driven load at the opposite end. The tachogenerator produces 3 V/1000 rpm, providing a linear signal that the drive card uses to monitor speed deviations. The motor includes tachofeedback and a second shaft end, allowing the additional shaft interface to support an auxiliary encoder or a mechanical load while analog velocity feedback remains available. Standard tacho quality provides the accuracy needed for typical analog velocity loops. The cable orientation also helps keep the connection path organized when the motor is mounted near surrounding machine components.
