Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI673LV/S001 is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed as a compact rotary actuator, it converts electrical energy into controlled torque for indexing tables, feed rolls, and small pick-and-place axes that rely on analog drive amplifiers. By pairing tachometer-based feedback with precision winding geometry, the unit delivers stable speed regulation and rapid start-stop cycles in general factory automation. Its compact format suits machine sections where limited space and quick response are both important.

With a cooling method based on natural convection, the motor dissipates heat without external blowers, so cabinet airflow requirements remain minimal. The electromagnetic stack uses motor length 041, while the frame cross-section follows size code B. Power is routed through a connector on side B, allowing cable exits that keep service loops clear of moving parts. Rotor position is reported by an incremental encoder with standard mounting, supplying quadrature pulses that an analog controller converts to velocity and position signals. This feedback arrangement supports stable low-speed regulation and repeatable stopping on light indexing mechanisms.

For installations that must brake through drive torque alone, the unit is supplied without a blocking brake, reducing inertia on compact axes. The optional sensor set provides tachometer feedback with incremental or absolute encoder signals for applications that require additional feedback options. Its classification as a motor for analog drives supports use with legacy transconductance amplifiers still common in older transfer lines. As part of the MAC AC Servo Motors series, it uses the same style of mechanical flange, feedback pinout, and power connector orientation found across that product line.
