[Case Study] Variable Speed Control Specifications for Pearldex

Achieving optimization of production takt time! A case where the versatility and flexibility of the equipment have significantly improved.

We would like to introduce a case where the introduction of the "PDW Series," which involved changing to a three-phase induction motor, successfully addressed the challenge of controlling indexing speed. The standard specification includes a single-phase induction motor, which has the limitation of operating at a constant speed due to its characteristics. As a result, there were cases where production sites raised more advanced demands to control the indexing speed according to the type of workpiece and the situation of the process. We proposed a solution to change the motor combined with the Pearl Decks to a "three-phase induction motor." This allowed for flexible adjustment of indexing speed through rotational speed control using an inverter. [Challenges] ■ There is a need for variable speed control to optimize takt time, such as low-speed operation to suppress vibrations during workpiece transport or high-speed operation to maximize production capacity. However, the standard motor may not meet these needs, which can prevent the overall performance of the equipment from being maximized. *For more details, please feel free to contact us.
