Product Description:

The MAC115B-0-GS-3-C/130-B-0/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives intended to deliver closed-loop speed and torque control in automated machinery such as printing presses and material-handling axes. By combining a wound stator with permanent-magnet excitation and integrated tacho feedback, the unit supplies real-time velocity data to an external drive controller, allowing precise regulation without digital bus hardware. This arrangement suits applications that rely on analog command structure and need stable motion response without added communication interfaces inside the motor.

The motor uses a centering diameter of 130 mm, providing concentric alignment when the flange seats against mating machinery. Heat is removed through natural convection, so the installation must permit free ambient airflow instead of relying on forced cooling. Under rated load, the rotor turns at a nominal speed of 2000 rpm, which supports common servo duties where steady speed and repeatable acceleration are required. The built-in tacho generator supplies 3 V/1000 rpm, giving the analog drive a continuous speed reference so it can correct small deviations quickly during operation. Power conductors are routed through a connector on side B, which can simplify cable routing when the motor is mounted with its rear extension oriented toward nearby machine components.

Because the motor has no blocking brake, any static load must be held by drive torque or by an external mechanical brake. The frame size is 115, and the motor uses length code B, which corresponds to the housing depth used for this version. Electrical behavior is tied to winding code GS, which sets the phase resistance and current requirements expected by the matching drive. Standard tacho quality and the second shaft end support applications that need an added pulley, handwheel, or similar accessory on the rear extension while leaving the main drive end available for the primary coupling.
