Product Description:

Bosch Rexroth Indramat manufactures the MAC041C-0-LS-3-E/050-A-0, an AC servo motor in the MAC AC Servo Motors series. The unit delivers closed-loop torque and speed control for pick-and-place axes, small conveyors, and assembly tooling, where stable rotary motion is needed for repeatable starts, stops, and short travel moves. Within an automation cell, the motor pairs with a matching Indramat drive to translate low-level voltage commands into deterministic rotation, providing the mechanical power required for precise positioning tasks and steady speed regulation during routine machine cycles.

Thermal management relies on natural convection, so heat dissipates through the housing without forced airflow. The motor has no blocking brake, making this model suitable for applications where the drive or external mechanics hold position when power is removed. Rotor position is monitored through integrated tacho feedback, and the design also provides a second shaft end for encoder coupling or mechanical takeoffs when additional feedback or auxiliary coupling is needed. The stator stack uses the 041 length index, which corresponds to the magnetic active length and influences continuous torque capability. Frame code C sets the mounting face dimensions used for this motor size.

Power is routed through a keyed connector located on side A, simplifying cable management inside compact machine frames and helping keep the cable exit aligned with nearby drive hardware. The stator windings use the LS designation, matching the impedance and inductance values expected by compatible drive amplifiers for stable current control. Because the motor is intended for analog drives, velocity and torque loops are closed directly inside the drive electronics, while tachometer feedback returns to the amplifier for regulated motor operation.
