Product Description:

The MAC093B-0-GS-4-C/110A-A3/WI522LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it receives proportional current from a servo amplifier to generate controlled shaft torque and speed in handling equipment, printing presses, and general motion axes. This control style suits legacy motion systems that rely on analog command signals rather than digital communication. The housing follows motor length code B, which gives it a medium active stack length that balances inertia and torque density. A standard tacho generator provides velocity feedback suited to analog control loops.

An extra heavy-duty blocking brake is fitted to hold the shaft when power is removed. Its holding torque is 22 Nm, which helps prevent load drift on vertical or overhung mechanisms. Mechanical alignment is simplified by a 110 mm centering diameter that mates with standard flange adapters and helps seat the motor accurately on the machine face. Heat generated in the stator is dissipated by natural convection, eliminating the need for forced air or liquid cooling. Winding code GS corresponds to the electrical characteristics used for the rated current range. Because cooling is passive, the motor can be used where external fan maintenance is undesirable.

The motor has a nominal speed of 4000 rpm, allowing fast cycle times without excessive mechanical stress. The built-in tacho generator produces 1.5 V/1000 rpm, a proportional signal used by analog regulators to stabilize velocity under varying load. Frame size 093 indicates the stator diameter and supports compatibility with gearboxes that use the same bolt circle. For position loops, an incremental encoder can be specified with standard mounting, enabling count-based positioning while keeping the overall length unchanged. This arrangement supports speed-regulated operation and position supervision in machines that continue to use analog amplifier architecture.
