Product Description:
The MAC041B-0-BS-4-E/050-B-1/WI674LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It provides closed-loop torque and position control for material-handling, packaging, and general automation equipment that require precise axis movement in a compact installation space. When paired with a compatible drive amplifier, it converts commanded current into controlled shaft rotation for indexing, transfer, and positioning tasks across repetitive duty cycles. The motor is intended for applications where repeatable motion, stable speed feedback, and reliable holding behavior are needed during normal operation and controlled stops. Its compact design makes it suitable for machinery that must fit a servo axis into a limited mounting envelope without adding external cooling hardware.
The motor has a frame size of 041 and a frame length of B, giving it a compact housing for machines with limited mounting depth. Cooling is provided by natural convection, so heat is removed through the ribbed housing without fans or liquid circuits. A standard blocking brake is integrated to lock the shaft when control power is removed, which helps hold vertical or suspended loads in place. Power is routed through a connector on side B, keeping the cable exit at the non-drive end for straightforward routing in enclosed machine layouts.
Rotor position and speed are monitored through a tachofeedback incremental or absolute encoder interface, which supports feedback processing for the connected drive. The factory configuration includes an incremental encoder with standard mounting that generates two-channel sinusoidal signals for analog velocity control. As a motor for analog drives, the unit is matched to classic Indramat control concepts that use phase-aligned feedback for current control and stable low-speed operation. The encoder arrangement allows the drive to monitor rotor movement continuously during acceleration, steady-state running, and deceleration. This helps the axis maintain repeatability in machines that cycle frequently under changing loads.
