Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI670LV is an AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is intended for use with analog drive amplifiers, where commanded current is converted into controlled shaft motion for light-duty positioning and repeatable speed regulation. Its compact construction suits pick-and-place units, transfer mechanisms, and other machines that need closed-loop servo action without giving up installation space around the axis. A smaller housing can also reduce the burden on supporting structures when the motor is mounted near slides, pivot arms, or compact rotary assemblies.

Cooling is handled by natural convection, so the housing must remain exposed to free air during operation. The motor uses size B for its frame code, and the 041 length identifies the axial body size within this platform. Power wiring exits through a connector on side B, which keeps the opposite end more accessible for adjacent machine hardware. That cable direction can simplify layouts where the motor is installed close to a plate, guard, or coupling on the front side. The motor has no blocking brake, so any load that must stay fixed after power removal requires an external holding method or drive-generated holding torque.

Position feedback is provided by an integrated incremental encoder with standard mounting, allowing the connected controller to process speed and position signals directly from the motor. The cable arrangement also supports tacho feedback with an incremental or absolute encoder when a different feedback scheme is required by the application. Classified as a motor for analog drives, the unit is matched to control systems that use analog command signals instead of network-based motion control. This setup fits established servo platforms that rely on dedicated amplifier tuning and direct feedback processing. Using onboard feedback can also eliminate the need for a separate external measuring device on many basic motion axes.
