Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI673LV/S001 is a compact AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a rotary actuator in analog control loops, translating ±10 V drive commands into controlled shaft movement for pick-and-place systems, small transfer stations, and light assembly equipment. The motor’s permanent-magnet design, combined with integrated position sensing, supports stable velocity regulation and accurate positioning in space-constrained industrial installations. Its compact housing also helps it fit machinery where installation space and cable clearance are limited.

The electromagnetic package is identified by winding code FS, which sets the motor’s nominal voltage constant and allowable current so it matches analog servo amplifiers used on small axes. Frame size 041 sets the stator diameter, while length code A marks the active core stack depth; together these dimensions support continuous torque output without forced cooling. Heat generated in the windings is removed through natural convection, eliminating the need for external fans or liquid circuits. This cooling method keeps the motor mechanically simple and avoids auxiliary cooling connections. For applications that depend on mechanical holding during power loss, it is important to note that this model is supplied without a blocking brake, so any static load must be restrained by external means or by drive torque.

The power leads exit through a connector on side B, simplifying right-angle cable routing inside compact cabinets and helping keep the motor end clear in tightly packed assemblies. Rotor position is monitored through tacho feedback with an incremental or absolute encoder, and the customer-specified build identified here incorporates an incremental encoder with standard mounting to deliver velocity and position signals compatible with classic analog drive cards. As a motor for analog drives, the unit maintains the signal levels and electrical isolation common to legacy control architectures while still providing precise servo performance for modernized machinery. This combination allows the motor to work with older control hardware without giving up closed-loop motion control.
