Product Description:

The DD045CB4ANEA200 belongs to the Linear Servo Motors series manufactured by Sanyo Denki. This coil assembly provides the driving force for a linear axis, allowing production machinery to position loads directly along a track without ball screws or belts. By combining an iron core, permanent-magnet rail, and built-in feedback device, the unit converts controlled current into smooth thrust for pick-and-place modules, inspection gantries, and other precision automation cells.

The factory-terminated cable extends 600 mm from the housing, easing routing inside compact carriers, and the coil weighs 8.6 kg, which must be considered when calculating the moving mass. A matching drive that can source up to 75 A is required; this current produces the rated operating point of 1.9 m/s at a continuous thrust of 800 N. Eight M6 threaded mounting holes secure the coil, and each hole has a depth of 9 mm. Two precision dowel seats with a diameter of 4 mm and a tolerance of +0.02 mm align the assembly, while an auxiliary 6 mm locating pin hole accommodates secondary fixtures. The threaded holes provide secure fastening, and the dowel seats maintain consistent coil alignment relative to the magnet track.

For transient moves, the stage can accelerate to 3.0 m/s and develop a peak thrust of 2200 N before thermal limits intervene. The magnetic attraction between the coil and magnet track reaches 600 N, so the carriage must counteract this constant preload. The motor includes a Hall sensor that supplies commutation signals to the amplifier and supports coarse homing without an external switch. Because the Hall signals indicate the electrical phase position, the controller can energize the windings in the proper sequence from startup and maintain directional thrust during motion. Proper support for the attraction force helps prevent unwanted carriage deflection and keeps the air gap consistent as the stage travels along the magnetic rail.
