Product Description:

The DS050CD1ANEA200 is a coil module from the Linear Servo Motors series produced by Sanyo Denki for direct-drive positioning stages and gantries that need fast, stall-free linear motion. By interacting with a separate magnet track, the coil converts drive current into thrust without intermediate gearboxes or ball screws, which simplifies mechanical layouts in semiconductor handlers, pick-and-place heads, and packaging machinery. An integrated Hall sensor supplies coarse commutation feedback to the amplifier.

This model pairs with amplifiers that can deliver up to 30 A, so the drive channel must be sized for the required current to avoid current limiting. The active copper stack spans 145 mm, providing a long electrical path that supports a high motor constant while maintaining a compact overall length. A coil mass of 2.15 kg minimizes moving inertia, which improves acceleration and shortens settling time after rapid position changes. The magnetic circuit produces an attractive force of 2000 N, so the mechanical design must account for this preload even when the carriage is unpowered. The coil can generate a peak linear thrust of 630 N, allowing quick index moves or rapid acceleration of moderate payloads.

Installation tolerances center on an air gap of 0.6 mm when the optional cover is used; removing the cover increases the clearance to 0.7 mm and slightly reduces flux density. The assembly reaches a maximum travel velocity of 3.0 m/s, so cable management systems must withstand high reciprocating speeds. Eight mounting points with a thread arrangement of 8 × M5 secure the coil against a reference surface that is only 7 mm deep, helping keep the installation height low. The coil can produce a continuous process force of up to 340 N at the rated speed of 2.0 m/s, while its 71 mm width and 48.5 mm height allow it to fit within narrow machine envelopes.
