Product Description:

The MAC041B-0-BS-4-E/050-A-1/WI673LV/S006 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. In automated machinery, it converts electrical energy into precise rotary motion so that axes in assembly cells, packaging machines, and pick-and-place gantries stay synchronized with command signals. The combination of permanent-magnet excitation and closed-loop feedback makes the unit suitable for applications that require stable speed control, repeatable positioning, and rapid acceleration without adding gearbox backlash. This behavior is useful on indexing axes and synchronized transfer movements.

A passive thermal design based on natural convection disperses heat, so no external blower or liquid jacket is required and cabinet layouts remain simple. Frame data identify the motor as motor size 041 with a stack length coded B, a combination that sets the magnetic volume available to the connected amplifier. Power is routed through a connector on side A, letting cable trays follow the machine structure without crossing the feedback end. This arrangement helps preserve shielding on the high-current leads and keeps routing direct in compact machine sections. The passive cooling arrangement also reduces maintenance points and avoids fan-generated airflow around nearby components.

For load-holding duties, the motor is supplied with a standard blocking brake, so vertical axes can maintain position when the amplifier is disabled. Motion feedback may be provided through tacho feedback or an absolute encoder, allowing the drive to support either velocity regulation or power-on position retention. The dedicated sensor interface also accepts an incremental encoder with standard mounting when simple quadrature counts are enough. Because the windings and sensors are optimized for a motor for analog drives, the unit can be used in existing ±10 V control loops while keeping signal compatibility within the MAC platform. That flexibility helps the same motor fit both simple speed-control axes and applications that need stored position data after a restart.
