Product Description:

The MAC112B-0-LD-3-C/130-B-1/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts electrical commands from motion controllers into controlled shaft rotation for positioning and speed regulation in automated machinery. The built-in blocking brake secures the load whenever power is removed, and the standard tachogenerator on a secondary shaft delivers speed feedback to compatible drive amplifiers. Because both functions are integrated into the motor, the axis can provide controlled stopping and continuous speed feedback without separate external devices. This arrangement suits gantries, packaging lines, and other equipment that require closed-loop motion control with stable stopping behavior.

The motor body is guided into mounting fixtures by a centering pilot of 130 mm, which helps align the machine frame with the rotor axis. Heat is removed through natural convection, so no external blower or liquid circuit is required. Installation must permit free airflow along the housing fins for consistent heat dissipation during operation. During deceleration or standby, the integrated brake can hold up to 45 Nm, helping prevent back-drive on vertical axes or other gravity-loaded mechanisms. Nominal speed reaches 2000 rpm, which suits gear-reduced and direct-drive layouts used with medium-inertia loads. Power is supplied through a single connector on side B, allowing cable routing away from the driven shaft. This connector position can also help keep the cable path clear of rotating couplings and adjacent machine parts.

The tachogenerator outputs 3 V/1000 rpm, giving the analog drive card a proportional signal for velocity control without a digital encoder. This feedback is provided through tacho feedback with a second shaft end, which also allows connection to external sensors or handwheels. Electromagnetic behavior follows winding code LD, which matches 300 V class power modules and supports the expected current characteristics of the motor. With a motor size 112 frame and the associated B-length stack, the unit offers mid-range torque density while remaining compact for retrofit into existing machine layouts. The frame size and winding combination make the motor suitable for applications that need steady analog speed regulation and dependable holding capability at standstill.
