Product Description:

The MAC090A-0-ZD-4-C/110-A-0/WI504L is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts electrical energy into controlled mechanical torque and speed, enabling closed-loop motion control on conveyor, packaging, and machining axes that still rely on analog command signals. The unit interfaces with drive amplifiers that modulate voltage and current in response to process demands, making it suitable for automation cells that require consistent velocity and positional accuracy. Its analog-drive design also fits existing systems that use external amplifiers rather than integrated digital control modules.

The mechanical interface uses a centering diameter of 110 mm, allowing the flange to seat concentrically in standard machine frames and minimizing runout. Heat is removed by natural convection, so airflow around the housing must remain unobstructed for continuous duty. Under rated excitation, the rotor reaches 1500 rpm, a speed suited to mid-range torque while keeping vibration low. Power enters through a keyed circular connector located on side A, which can simplify cable routing when the motor is mounted with the shaft facing forward. Electromagnetic behavior is tied to winding code ZD; this code indicates the coil impedance set and the current the paired analog drive must supply during acceleration and steady-state load conditions.

The motor is supplied without a blocking brake, which reduces mass for high-cycle applications and requires external holding when the axis is at rest. Integrated tacho feedback generates a speed signal, and the secondary channel accepts an incremental or absolute encoder so the controller can use either relative counts or multi-turn position data. Standard tacho quality helps maintain repeatable output, and the tachogenerator produces 3 V/1000 rpm, giving the drive a linear voltage reference across the stated speed range. This feedback arrangement supports stable speed regulation during positioning and process control tasks. The position sensor is mounted with standard alignment hardware, matching its classification as a motor for analog drives in legacy and retrofit motion systems.
