Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI652LV is a compact AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts controlled stator current into rotary torque for accurate positioning and speed regulation in industrial automation equipment. Its compact housing is suitable for pick-and-place actuators, light gantry axes, and other machinery with limited installation space. Closed-loop control allows the connected drive amplifier to correct motion as operating loads change.

Heat is removed through natural convection, so the installation must provide unobstructed airflow around the motor housing. The motor is supplied without a blocking brake, which reduces mass and eliminates brake-release wiring. When power is removed, a vertical or externally loaded axis must be held by drive torque, a mechanical lock, or an external clamp. The motor has a frame size of 041, which establishes its compact stator and flange envelope. Its housing uses motor length B, providing additional active material while maintaining low rotor inertia for responsive acceleration. The position sensor uses standard mounting, providing a conventional mechanical interface within the feedback section.

Power wiring exits through a connector on side B, allowing the cable route to be directed toward the corresponding side of the housing. The cable should have enough clearance to avoid sharp bends and excessive strain near the connector. Rotor speed and position can be monitored through a combined tacho feedback system with an incremental or absolute encoder, allowing the controller to obtain velocity feedback and position information from the same motor assembly. The unit is a motor for analog drives, making it suitable for compatible closed-loop amplifiers that regulate motor current and velocity from analog command signals. Its winding code BS identifies the installed stator configuration, while the 050 centering dimension supports accurate alignment at the mounting interface. These operating characteristics support controlled motion without requiring forced-air cooling or an integrated brake mechanism.
