The range of products of newest and linear motor of Danaher/Kollmorgen is Platinum DDL, can offer without core structure (primary and there is attraction between sub part) with core structure (the great power that provides unit structure measure is outputted) .
Industry obtains electromotor of UL attestation linear the first times to rotating the insulation system integrality of servo electromotor and product security undertake attestation, people thinks to manage ought to, but undertaking attestation to linear electromotor is a big news.
The core of steel of new-style LC series that the subsidiary Anorad of Rockwell Automation weighs it does not have a product in brushing linear electromotor in Feburary 2003 “ takes the lead in ” obtains UL attestation. Explanation of Michael Backman of chief inspector of Anorad company market says, the structure do not have casing that the insulation requirement with additional UL gives these electromotor put forward function and enclose a challenge. A kind of new insulation system and electromotor coil design provide understanding definitely plan, achieved H level 180 ℃ protection and grade of voltage of 650V dc bus line. In addition, magnetic body of new generation rare earth was used in development of LC series electromotor, make force density rises somewhat than the model previously.
Say according to Anorad, finite yuan analytic law is used to optimize the LC linear electromotor of patent application is statified steel core design, the copper that this kind of design allows to be as high as 85% in the fill in coil group (than going up electromotor of generation steel core is tall 7% . ) . Steel core and the existence of a large number of copper material improved thermal efficiency. Original, model of two kinds of electromotor has measure of two kinds of coil, offer 62 pounds strength and output of 94 pounds strength. The three-phase of LC electromotor and standard is not had brush servo gearing compatible. Exchange the servo gearing of feedback to need, can give the installation using a group of electromotor module of suddenly Er effect. Use the control equipment that supplies this kind of function to realize electromotor inverting likely still with software.
