Product Description:

The MAC041C-0-LS-4-E/050-A-0/WI671LV/S001 servo motor is supplied by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a compact rotary actuator, this model is intended to operate with analog velocity and current controllers commonly used in legacy and retrofit automation lines. Its purpose is to translate proportional drive commands into repeatable shaft rotation, allowing pick-and-place axes, indexing conveyors, or small tool heads to hold programmed speeds under varying mechanical load. The compact MAC platform is suited to machinery where repeatable motion is needed without a large motor body, especially on axes that cycle frequently during normal production.

Mechanically, the unit uses housing size C, giving a narrow motor profile suited to tight mounting envelopes, while length 041 indicates the active stack depth and continuous torque profile. The electromagnetic circuit follows winding code LS, a selection that sets the phase resistance and voltage constant so the motor couples correctly to standard 50 V supply rails. Heat generated in the windings is removed solely by natural convection, eliminating the need for auxiliary blowers in sealed cabinets. For stopping and holding duties, the axis is supplied without a blocking brake, so holding force must be provided by the external drive or machine restraint. This arrangement keeps the motor package simple and avoids the added wiring associated with an internal brake or forced-air device.

Electrical interfaces are grouped on a connector on side A, enabling cable runs to follow the machine frame without sharp bends. For feedback, the motor can return tacho, incremental, or absolute encoder signals to an analog drive controller, and the standard assembly ships with an incremental encoder with standard mounting for typical velocity loops. Because it is a motor for analog drives, signal scaling, excitation voltages, and commutation phasing align with classic Indramat transconductance amplifiers. This layout supports stable speed regulation on installed analog systems and helps the motor fit existing machine harness routes without changing the basic control method.
