Product Description:

The Bosch Rexroth Indramat MAC112B-0-GB-3-C/130-A-1 belongs to the MAC AC Servo Motors series. It is a motor for analog drives used to deliver controlled torque and speed to machining centers, printing equipment, and material-handling axes that are governed by analog servo amplifiers. The model produces a continuous velocity signal through an internal tacho generator on its second shaft end, allowing closed-loop regulation without digital field buses. It is suited to applications that depend on steady speed regulation and predictable response from analog command signals. Its round-flange housing matches other motors in the series, which helps it fit legacy machine layouts.

The motor uses size code 112 with a centering diameter of 130 mm, so it fits MAC mounting patterns in this frame class. A standard blocking brake rated at 45 Nm holds the shaft during shutdown and helps prevent axis drift when power is removed. Heat from the stator is dissipated through natural convection, so no blower or liquid circuit is required. This cooling approach keeps the motor layout simple and leaves more installation space around the housing. It also avoids added fan hardware around the motor body.

The feedback arrangement combines tacho feedback and a second shaft end, so an encoder or other accessory can share the drive side without extra couplings. With standard tacho quality, the motor supplies the analog controller with a low-ripple speed signal across the operating range. The motor has length code B, which gives it a medium housing depth that balances inertia and torque output. Power is routed through a connector on side A, allowing cables to exit toward the cabinet and stay clear of nearby axes. This layout can simplify cable routing when multiple driven components are installed close together.
