Product Description:

The MAC041A-0-FS-4-E/050-A-1/WI670LV is a compact AC servo motor supplied under the MAC AC Servo Motors series by Bosch Rexroth Indramat. Designed as a motor for analog drives, it delivers closed-loop motion control for positioning axes, pick-and-place units, and light conveyor stations where precise speed and torque regulation are required in industrial automation. Its compact format also suits installations where available mounting space is limited but repeatable motion is still required. In automated equipment, it works well on axes that need stable response during frequent starts, stops, and short positioning moves.

For holding duties, the motor includes a standard blocking brake that secures the shaft whenever drive torque is disabled. Thermal energy is removed solely by natural convection, so the housing fins must remain unobstructed during continuous operation. The motor uses winding code FS, which sets phase resistance and inductance so analog drive amplifiers can apply the correct current loops. Position and velocity are derived from an incremental encoder with standard mounting, and the feedback assembly also includes a tachometer channel. Power conductors exit through a connector on side A, which can simplify cable routing when the motor is installed with its A-side toward incoming cable trays.

The mechanical envelope corresponds to length code 041 and frame designation A, a size combination that balances low inertia with enough continuous torque for medium-duty automation axes. The small frame helps reduce moving mass on short-stroke mechanisms, which can improve response in indexing and transfer tasks. This length uses common seal kits and bearings across the same housing size, which helps keep service parts consistent. The remaining interface characteristics suit legacy analog amplifiers, so the motor can be integrated into existing control layouts without changing motor-side hardware.
