Product Description:

The MAC041B-0-QS-4-E/050-A-0/WI651LV/S006 is an AC servo motor in the MAC AC Servo Motors series. Designed as a compact rotary actuator, it supports closed-loop motion on pick-and-place gantries, indexing tables, and light material-handling stations. A permanent-magnet rotor works with integrated feedback to provide repeatable positioning and stable speed control in automated assembly and packaging equipment. The motor converts current commands from the drive into controlled shaft rotation, helping axes accelerate, settle, and reverse direction with predictable response. Its compact format suits machines that need accurate motion without a large installation footprint.

The motor uses size code 041 with frame designation B, which gives it a compact active core for light-duty servo axes. Heat from winding losses is removed by natural convection, so no external blower or liquid circuit is required and the installation should leave room for free airflow around the housing. Because cooling depends on the housing surface, tightly enclosed mounting spaces can reduce heat dissipation during continuous operation. The motor has no blocking brake, so the axis must rely on drive torque or an external holding device when power is removed. Power conductors enter through a connector on side A, and the unit is built as a motor for analog drives.

Motion feedback is available through a package described as tacho feedback, incremental encoder, or absolute encoder, allowing the connected drive to process speed signals or full position information. This version is equipped with an incremental encoder with standard mounting, which supplies quadrature pulses for accurate phase alignment without increasing overall motor length. The E execution with a 50 mm centering diameter supports mounting alignment on compatible machine faces. In applications that use velocity and position loops, that feedback arrangement helps the controller track motor response during acceleration, deceleration, and settling.
