Product Description:

The MAC041C-0-LS-4-E/050-B-0/WI671LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for precision motion control, it converts drive commands into tightly regulated rotary movement for light to medium industrial axes such as feeders, wrappers, or pick-and-place stations. Permanent-magnet excitation, real-time feedback, and a compact housing allow the unit to maintain commanded velocity and position under the variable loads commonly encountered in automated assembly and packaging equipment.

The motor uses a C frame size stator that keeps the outer diameter compact while still permitting practical torque output. Its active section uses the 041 length code, so the magnetic stack is suited to short mechanical envelopes without sacrificing dynamic response. The electromagnetic circuit uses the LS winding, which matches the current and voltage limits of classic Indramat analog amplifiers. Internal heat is dissipated solely through natural convection cooling, so the mounting layout must support free air circulation rather than forced ventilation. For power, the motor uses a sealed connector on side B, separating high-current conductors from the feedback plug and directing cables away from moving machinery.

Mechanical holding is external because the assembly includes no blocking brake. Closed-loop control is enabled by tachofeedback, incremental encoder, or absolute encoder feedback, giving the drive electronics the speed or position signals required for regulation. The motor’s integrated sensing element is an incremental encoder with standard mounting, which supports straightforward integration with common evaluation cards. When wired to a compatible converter, it functions as a motor for analog drives and supports the legacy ±10 V command interface still used in many long-life production lines and test rigs.
