Product Description:

The MAC090C-1-GD-4-C/110-A-2/WI521LV/S013 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It couples to analog servo amplifiers to translate command voltages into precise shaft rotation for indexing tables, packaging lines, and material-handling axes in automated plants. This arrangement supports controlled motion where repeatable speed and stopping behavior are required.

To hold static loads securely, the motor is fitted with a heavy-duty blocking brake that clamps the shaft when the amplifier is disabled or when power is lost. Ventilation for the internal windings is driven by an external blower rated at AC 230 V, allowing the cooling fan to use a common plant supply. The housing centers on a 110 mm pilot diameter, giving a repeatable reference for flange mounting and reducing radial misalignment. Thermal energy is removed through axial surface cooling, where air moves along the stator length to support continuous torque while keeping the frame compact. The GD winding code matches the electrical characteristics to compatible drive outputs for balanced current and manageable temperature rise. Position information is generated by an incremental encoder with standard mounting, supplying evenly spaced pulses for velocity and position loops within the analog drive.

The power leads exit through a connector on side A, so cable routing follows the motor's left side when viewed from the shaft and can stay clear of nearby machine parts. Classified as a motor for analog drives, the unit uses electrical constants intended for voltage-controlled servo amplifiers with classic PI current regulation. Speed feedback uses standard tacho quality, providing predictable linearity between back EMF and the speed signal. The wiring set supports tachofeedback with an incremental or absolute encoder for applications that require absolute position capture.
