Product Description:

The MAC041B-0-QS-4-E/050-A-1/WI652LV is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This rotary actuator converts controlled electrical input from matching drive amplifiers into precise shaft torque and speed for automated equipment. By integrating into closed-loop motion axes, it allows pick-and-place units, feeders, and light-duty conveyors to execute repeatable moves, synchronize with sensors, and maintain positional accuracy during production cycles. In automated stations, this response helps the axis follow commanded motion profiles while correcting for minor load changes. Its operating profile suits compact automation tasks that require frequent starts, stops, and short indexing moves.

Heat generated in operation is dissipated through natural convection, eliminating the need for external blowers or liquid cooling and simplifying cabinet layout. Rotor position signals are produced by an incremental encoder with standard mounting, allowing the associated drive to count pulses for velocity and displacement control with low latency. The feedback package also includes tacho feedback for analog speed monitoring. The motor uses frame size 041 and length code B, and a factory-installed blocking brake is standard so the load can be held when power is removed on vertical or safety-critical axes. This cooling method also keeps the installation free of auxiliary fan wiring.

For electrical wiring, the power leads exit through a connector on side A, which orients the cable toward the driven machine and keeps connector positioning consistent across the installation. The motor is classified as a motor for analog drives, meaning it is intended to run from voltage-controlled amplifiers that process ±10 V command signals rather than fully digital fieldbus interfaces. This control style is common in legacy servo systems that exchange command values as analog voltage levels. It lets the amplifier regulate torque and speed through continuous command signals instead of packet-based network updates. The arrangement supports coordinated axis motion where stable feedback and direct analog command handling are required.
