Product Description:

The MAC090B-0-ND-4-C/110-A-2/WI522LV/S013 is part of the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives and is intended for automated machinery that requires closed-loop speed and position control, such as packaging lines and material-handling axes. By combining magnetic torque generation with integrated feedback devices, the unit converts drive commands into precise rotary motion that can be coordinated with PLC sequences. In this type of system, motion can be corrected continuously as operating conditions change during the machine cycle. That operating style suits repetitive axis movement where stable response and accurate following are required throughout production.

A built-in heavy-duty blocking brake secures the shaft when the drive is disabled, allowing vertical loads to remain stationary without external clamps. Cooling is done through natural convection, so the installation must maintain free airflow around the housing instead of relying on fan or liquid cooling. Power is routed through a connector on side A, which can simplify cable routing when the motor is mounted with the flange toward the machine frame. Accurate centering is provided by a 110 mm pilot diameter that aligns the motor to the mating surface. This mounting arrangement supports repeatable installation and helps keep the shaft axis aligned with the driven mechanism. It also allows the motor to fit common machine interfaces used for this frame style.

For velocity regulation, the drive reads tacho feedback, allowing the controller to monitor motor speed continuously during operation. Shaft position is monitored by an incremental encoder with standard mounting, which provides high-resolution pulses for phase-locked drive control. The motor also uses standard tacho quality components to keep ripple within the tolerance required by analog amplifiers. This feedback arrangement gives the connected control system separate information for speed regulation and position evaluation during coordinated motion. The resulting signal set supports stable low-speed behavior and consistent tracking when the axis must follow changing motion commands.
