Product Description:
Bosch Rexroth Indramat manufactures the MAC041B-0-BS-4-E/050-A-1/WI652LV as part of the MAC AC Servo Motors series. The unit is an AC servo motor intended for analog velocity and position loops in industrial automation. When paired with compatible servo drives, it turns electrical commands into controlled shaft movement for compact axes in pick-and-place machines, small conveyors, and indexing tables. It uses permanent-magnet excitation and a rotor-stator assembly optimized for low inertia, making it suitable for dynamic but moderate-power axes where electronic analog drives are still installed in legacy lines.
The motor size is 041 and it has a compact B length, giving it a short overall body that fits limited mounting depths while maintaining standard MAC interface dimensions. Heat is removed through natural convection, so the motor can operate without forced air or coolant lines and cabinet layout remains simple and quiet. A standard blocking brake is integrated to clamp the shaft whenever power is removed, preventing drift on vertical or safety-critical axes. Power is delivered through a connector on side A, allowing cable routing along the drive side of the machine and reducing interference with feedback wiring at the opposite end.
The signal path relies on an incremental encoder with standard mounting, providing phase-quadrature pulses that an analog controller converts into speed and position signals. For systems that need velocity linearization, the extended feedback option combines tacho feedback with an incremental or absolute encoder, supplying both pulse trains and a proportional voltage. Within the drive architecture, the unit is classified as a motor for analog drives, so it accepts the ±10 V command standard common to earlier Rexroth amplifiers. This arrangement supports closed-loop speed and position control without requiring separate external feedback hardware.
