Product Description:

The MAC090A-0-ZD-4-C/110-A-0/WI522LV/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. This motor is intended for analog drive systems where a velocity or current loop is closed in the drive controller rather than within the motor housing itself. By combining the electromagnetic stack assigned to the ZD winding with an integrated tacho and encoder package, the unit delivers the position and speed signals required for mid-range motion axes in packaging lines, material-handling gantries, and general automation cells. This arrangement lets the external drive process feedback directly while the motor remains a compact rotary actuator for coordinated machine movement.

The mechanical interface is fixed by a 110 mm centering diameter, allowing the flange to seat directly against precision-ground machine faces. Heat is removed through natural convection, so no external fan or liquid circuit is required when the motor operates at its rated load. Shaft rotation is specified at 1500 rpm, a speed selected for drives that must balance torque production with low acoustic noise. The ZD winding code identifies the coil arrangement used for compatibility with the corresponding analog amplifier range. A built-in tacho generator provides a calibration factor of 3 V/1000 rpm, furnishing the drive with an analog velocity feedback signal proportional to actual shaft speed.

A blocking brake is no blocking brake, so vertical loads must be secured by external means during power-off states. Main power conductors enter through a connector on side A, simplifying cable routing in cabinets where multiple axes share a common harness path. Tacho performance is graded as standard, which is suitable for routine speed regulation in general automation service. Position data can also be obtained through a tacho feedback incremental or absolute encoder, providing an additional feedback channel for position monitoring. This combination allows the motor to support both speed regulation and position-related control functions without adding an external sensing assembly.
