Voice coil motors offer precision motion in compact packageINMOCO is adding the Juke Series voice coil motor from the American manufacturer Celera Motion to its portfolio of high-performance drives and actuators. The Juke Series motors are designed to enable OEMs to move light payloads with high acceleration and dynamic motion profiles. They offer smooth, jitter-free motion, short settling times and accurate positioning. Formats available include both round-bodied and flat-bodied designs, and moving-magnet and moving-coil configurations. Typical fields of application include the manufacture of semiconductors and focusing of precision optical systems.

To aid simple installation and commissioning, the motors do not require commutation, which simplifies wiring and increases system reliability in use. This feature helps to make them compact and enables easy integration into lightweight precision assemblies.

As a simple two-wire device, the Juke series motor can be controlled with readily available amplifiers and PID controllers. Coupled with precision encoders of 5nm resolution, they are able to offer positioning to an accuracy of 1 micron. With a footprint of only 13 x 11.8mm, plus versatile mounting and cabling options, they are easy to integrate into host machinery such as small linear stages.

The round-bodied motors offer a peak force of 5-46N, strokes of 22–40mm and continuous power of 3–18W; physical dimensions are 19-32mm wide by 25–38mm long. The flat-bodied counterparts provide 8–175N peak force, 6–20mm stroke and 25–25W continuous power from a unit 55–140mm wide by 40–120mm long. For both types of Juke motor, when paired with a precision encoder, resolution of 5nm, accuracy of 1 micrometre and repeatability of 1 nanometre are achievable.

Available in standard sizes and formats, custom options can also be developed to match specific application requirements.
