Product Description:

The MAC093B-0-JS-4-C/110-B-2/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it translates command voltages from legacy controllers into controlled rotary motion for production equipment. The 093 frame size and B length code give the motor a medium footprint that fits inline gear stages and belt transmissions where space is limited but consistent dynamic response is still required. This layout makes it suitable for machinery that depends on repeatable speed changes, steady torque delivery, and compatibility with established control hardware.

The motor is equipped with a heavy-duty blocking brake that delivers a holding capability of 14 Nm, so vertically oriented loads can remain in place when power is removed. Precise axial alignment is provided by the 110 mm centering diameter, which seats the flange against companion machinery with minimal radial error. Heat is removed by natural convection, so no external fan or coolant loop is required during normal operation. During rated operation, the shaft reaches 3000 rpm, which suits analog drive modules set up for this speed range. Standard tacho feedback on the auxiliary shaft supplies a proportional voltage for speed regulation in systems that do not rely entirely on encoder-based positioning.

Power conductors enter through a connector on side B, allowing cable runs to stay parallel with machine frames and reducing bend stress near the motor entry point. The integrated tacho generator produces 3 V/1000 rpm, while the main position sensor is an incremental encoder with standard mounting for digital servo loops and motion monitoring. This combination allows the motor to provide both analog speed-related feedback and encoder-based position information within the same housing. The feedback arrangement supports legacy controller layouts that still require a tacho signal while also using encoder data for more accurate axis supervision. Winding code JS identifies the electrical layout used for this motor and matches it to compatible MAC drive ratings for stable current regulation during acceleration and braking.
