Mitsubishi Electric Automation, Inc. has introduced Economy Solutions, packaged servo and motion bundles that allow for high precision motion control in a way that is quick and affordable to integrate.
Effective April 1, 2022, Dr. Fritz Faulhaber GmbH integrates subsidiary PDT Präzisionsdrehteile GmbH from Nürtingen and thereby welcomes 34 new specialists to the Schönaich location. Thanks to this strategically planned step, Faulhaber can, with a machining center of its own, respond more quickly to individual requests and expands competencies in the area of machining production.
NSK Ltd. has developed a new technology that significantly extends ball screw life in high-load drive applications. Products with this technology are expected to be adopted by industrial machinery makers shifting to electric designs. Through this and other technologies, NSK continues to contribute to electrification and productivity increases industrial machinery.
Transverse magnetic flux motors -- also known as step motors -- become Hybrid Servos when you operate them closed loop. This is the same transformation that happens between running a 3-phase synchronous motor from line voltage as opposed to running it closed loop as a brushless servo. In the case of hybrid motors, there are many degrees of what is advertised as "closed loop," and thus significant differences in the performance improvements seen.
The transverse flux permanent magnet motor -- also known as a hybrid step motor or hybrid servo motor -- has a wide range of performances, depending upon how you drive these motors, and whether you operate them in open loop or one of the many variants of closed loop methods you use. In this third installment we will cover some of the many ways to drive these motors, as well as how these choices affect the performance of these motors.
This is the first of a series of articles on permanent magnet transverse magnetic flux motors - AKA step motors. These articles will be covering the development history and the various drive technologies used with these motors - both open and closed loop.
