Electric vehicle (EV) charging infrastructure is a critical aspect for bringing EV adoption online. Key requirements include reducing range anxiety among users and supporting local and national environmental goals. When an EV infrastructure provider approached Dings Motion, they had already sourced a magnetic gearhead pump from a manufacturer overseas, intending to pair it with a NEMA 24 BLDC (brushless DC) motor. However, they encountered persistent communications issues, which included delays in technical support that hindered their ability to finalize the assembly and move forward with prototyping and testing prior to production. 

The complexity of integrating the pump with the motor presented additional engineering and supply chain headaches. What they needed was a partner that could overcome these initial roadblocks as well as one that could provide a custom product of high quality. The Dings Motion engineering team quickly identified an opportunity to streamline the development process by leveraging its strong supplier relationships to obtain answers to the client’s technical questions within days—compared to the months they had previously waited. 

To further reduce complexity, a turnkey solution was developed, sourcing the pump on the client’s behalf, assembling it to a Dings BLDC motor in-house, and delivering a fully integrated drive subsystem. This eliminated the need for the client to manage cross-continental component sourcing as well as system integration. 

The partnership between Dings Motion and their EV infrastructure client resulted in a customized motor and gear pump subassembly that matched the client’s performance specifications. Dings’ engineers were able to select from the company’s broad range of low-cost, customized BLDC motor solutions and match them with the right amplifier for the application. The advantages of brushless DC motors include speed regulation, higher power density, and overload capacity. The company produces NEMA sizes from 17 to 34 and with three different lengths per size. The final subsystem was fully compatible with Dings’ open-loop BLDC motor driver networked through RS485. 

The plug-and-play solution significantly simplified the client’s prototyping and testing process. By delivering a fully assembled subsystem, the client’s R&D process was accelerated, which greatly eliminated the pain points of overseas coordination. While the project is ongoing, early feedback indicates that the client has shortened their development timeline and minimized integration risks by sourcing a full solution rather than individual components and having to assemble and test them in-house.
