Product Description:

The MAC041B-0-BS-3-E/050-A-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It functions as a drive element that transforms analog velocity or position commands into shaft rotation for automated machinery, allowing precise motion control in packaging lines, small handling robots, and indexing tables. The motor is intended for applications that rely on external drive electronics to regulate current, speed, and position during operation. Its compact format also suits axes where repeatable rotary motion is needed without a large motor envelope.

This model relies on natural convection for thermal management, so heat is dissipated through the housing without auxiliary fans or liquid circuits. Rotor position is reported through tacho feedback and a second shaft end; the tacho supplies a proportional voltage for speed loops, while the extended shaft can carry an external encoder if higher-resolution feedback is required. Frame designation B indicates the stator diameter used in this MAC size, and it keeps the mounting dimensions consistent with gearboxes that use the same flange code. The power leads exit through a connector on side A, which keeps cable routing on one face of the motor and leaves the opposite side available for mechanical adapters or added feedback hardware.

No mechanical holding torque is provided because the motor has no blocking brake, so machines that need static load support must use external brakes or energized drive torque during idle periods. The stack length marked as 041 limits overall motor depth, which helps space-restricted gantry or turret assemblies while also limiting continuous power to the thermal capacity of that lamination length. Classified as a motor for analog drives, it matches legacy drive amplifiers that regulate current with analog command voltages instead of fieldbus protocols. It is part of the MAC AC Servo Motors series, which shares mounting accessories and related service parts with other MAC units.
