Product Description:

Bosch Rexroth Indramat manufactures the MAC041B-0-BS-4-E/050-B-0/WI668LV/S001 as part of the MAC AC Servo Motors series. The unit is a brushless AC servo motor that delivers position-accurate rotary motion for pick-and-place modules, small actuators, and light machine-tool axes in industrial automation cells. When combined with a compatible drive controller, the motor converts electrical commands into controlled shaft torque and velocity for synchronized closed-loop movement in multi-axis systems. Its compact format makes it suitable for installations where available mounting space is limited but precise motion is still required.

The motor has a frame size of 041 and a compact length code of B, giving it a short overall body for tight mechanical envelopes. Heat is removed by natural convection, so no external fan or liquid manifold is required. The motor has no blocking brake, so the axis must rely on drive torque or an external clamp to hold position when power is removed. Power conductors exit through a connector on side B, which helps keep cable routing clear of the motor body. The unit is a motor for analog drives, allowing it to work with legacy voltage-controlled amplifiers that use analog command signals instead of digital fieldbus control.

For speed regulation, the motor can use tachofeedback in velocity control loops. It can also work with an absolute encoder when retained position information after power loss is required, while the supplied configuration uses an incremental encoder mounted directly on the shaft. These feedback signals travel through shielded cables routed beside the power connection to reduce electromagnetic interference during rapid load changes. The drive can interpret the pulse train or analog tachometer output directly, which helps maintain fast response in analog motion systems without added interface hardware.
