Hi everyone, I'm the European Support Manager with Curtis instruments who manufacture motor controllers for battery powered vehicles, plus instrumentation and battery monitoring. We mostly sell into the materials handling and wheelchair markets, but in the last 10 years have done a fair bit in the Light On Road market. We mainly deal with induction motor controllers for everything except wheelchairs who still use PM motors. I've been working on applications for the last 16 years, varying from AGV's, forklifts, tow tractors, micro cars and utility vehicles. PMAC controls are on the horizon now that the market has expanded a little. Our AC controllers are very robust, can auto characterize the induction motor and work in the 24V - 96V, 150 -650Amp per phase with a programmable application layer.
My day jobs are control systems design and vehicle performance analysis.
