Product Description:

The MAC041A-0-FS-4-E/50-B-1/WI652LX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, the unit converts commanded current into controlled shaft motion for positioning and velocity loops found in pick-and-place stations, textile machinery, and packaging equipment. Its frame corresponds to motor size A and length 041, giving a compact diameter-to-length ratio that fits tight machine layouts without sacrificing continuous performance. Standard encoder mounting and tachometer or absolute encoder feedback options allow the drive to close control loops in either incremental or absolute coordinate modes. This type of motor is well suited to applications that require repeatable acceleration, stable speed control, and compact installation space.

The motor has a nominal speed rating of 6000 min⁻¹, which indicates the highest continuous mechanical velocity attainable at rated voltage and frequency. For holding or low-speed moves, the rotor can deliver a standstill torque of 0.59 Nm while drawing only 1.80 A, which indicates the static load the axis can support without rotation. Dynamic torque rises in proportion to phase current with a torque constant of 0.330 Nm/A, so the controller can predict output by monitoring current feedback. Velocity feedback from the integrated tachometer is linear and produces 0.75 V/1000 min⁻¹, which supports analog speed regulation circuits. Heat generated at these operating points is removed through natural convection, eliminating the need for external blowers or liquid circuits.

Mechanical integration is simplified by the B05 flange, a footless mounting style that mates directly to gearheads or machine plates. Power conductors exit on Side B, which keeps cabling away from adjacent axes when the motor is installed in close groupings. The holding brake, released by an electrical signal, secures vertical loads during shutdown and disengages automatically when 24 V is applied. This layout helps keep wiring organized in dense assemblies where multiple axes are mounted close together. Winding code FS tailors resistance and inductance to analog amplifiers, and the feedback-ready tachometer or encoder completes a closed-loop package without additional adapters.
