Product Description:

Bosch Rexroth Indramat manufactures the MAC041B-0-BS-4-E/050-B-0/WI656LV/S001 as part of the MAC AC Servo Motors series. This brushless servo motor is used in industrial automation systems where closed-loop motion control is needed to position tooling, conveyors, or indexing tables with repeatable accuracy. By converting electrical input from a servo amplifier into controlled shaft rotation, it provides the regulated speed and torque needed for coordinated machine operation during continuous or cyclic production. Its compact format makes it suitable for axes where installation space is limited but accurate motion and dependable speed control remain necessary.

The motor uses frame size 041 with length code B, giving it a shortened body that fits tight installation spaces while preserving the performance expected from this frame. Electrical power is routed through a connector on side B, so the cable run can stay parallel to the housing and reduce bend stress near the connection point. Thermal management relies on natural convection, so heat is dissipated through the motor surface in ambient air without an internal fan. The unit is supplied without a blocking brake, so any holding force at standstill must be provided by external mechanical means or by drive-applied torque.

Signal integrity is maintained by the integrated feedback chain. The motor uses a tachofeedback interface that allows the drive to monitor shaft motion directly and respond quickly to command changes. The built-in incremental encoder with standard mounting supplies low-latency pulses that support stable velocity regulation in analog control loops and consistent position tracking during normal operation. Because the unit is a motor for analog drives, it is intended for servo amplifiers that regulate current and speed through analog command voltages rather than through fieldbus-based control.
