Product Description:

The MAC093B-1-GS-4-C/110-A-2/WI538LV is an AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for closed-loop motion axes, the unit converts command voltages from analog drive controllers into precise torque and speed for automated equipment. Its design supports repetitive indexing, feed, and traverse functions in machinery that must maintain positional accuracy under variable load.

The motor’s heavy-duty blocking brake exerts 14 Nm of holding torque so vertical or suspended loads remain fixed when power is removed. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm, matching the dynamic range required by many packaging and handling lines. Mechanical alignment is supported by a 110 mm centering diameter that fits common gearbox flanges, while the size 093 frame pairs with the B length code to limit overall depth. Stator conductors use winding code GS, which indicates resistance and inductance values compatible with Indramat analog amplifiers. Thermal energy is removed by axial surface cooling with a blower supplied at AC 230 V, allowing continuous duty in typical cabinet temperatures. The tacho is standard for routine velocity monitoring.

In feedback terms, the motor is equipped with tacho feedback, and the position channel uses an incremental encoder with standard mounting. The tacho provides 1.5 V/1000 rpm to the velocity loop for fine speed correction, and power conductors are routed through a connector on side A to simplify parallel installation when several axes share a common manifold. Because the unit is supplied as a motor for analog drives, interface parameters such as a ±10 V speed command and tachometer feedback are aligned with legacy Indramat controllers, so the motor can be integrated without additional signal scaling.
