Product Description:

The MAC041B-0-BS-4-E/050-B-1/WI673LV is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is intended for precise positioning and speed regulation in automated machinery, where the drive amplifier commands controlled shaft motion. The motor supports stable response as load and temperature change, helping the connected axis maintain repeatable movement during continuous operation. Its compact format places it in the smaller portion of the series, which suits feeders, indexing units, and other axes that need accurate motion without the bulk of a larger motor.

Thermal management is passive because the motor uses natural convection, so heat leaves the housing without external blowers when surrounding airflow is adequate. Electrical power enters through a connector on side B, which keeps the cable run parallel to the stator axis and helps clear nearby machine components. Speed feedback is supplied by tachofeedback, providing an analog signal for velocity control loops. For power-off holding and emergency stops, the motor includes a standard blocking brake that engages automatically when supply voltage is removed. The 041 stack length helps keep rotor inertia low, which supports short acceleration and deceleration cycles on lightly loaded axes.

The housing uses the Size B outline, so the stator diameter fits common mounting flanges and gearbox interfaces in this frame class. Position feedback is provided by an incremental encoder with standard mounting, which supports consistent signal pickup without changing the motor's basic installation pattern. The unit is supplied as a motor for analog drives, making it suitable for systems that use legacy ±10 V command structures. Its cable exit arrangement, compact body, and integrated brake make it a practical choice for light gantries, transfer mechanisms, and similar axes that need repeatable motion in a limited installation space.
