Harry Hagerty

Harry Hagerty is a registered professional engineer in Pennsylvania. He has managed product development, and R&D involving direct technical design and oversight of internal as well as external resources. This includes solid state power electronics for motor control of SCR (Silicone Controller Rectifier) reduced voltage starters from small three phase motors up to 22,000 horsepower. Analysis includes SCR, heat sink and R-C suppressor design for soft starter product lines through 15kVAC as a core competency. He designed the first UL347 listed 5kV solid state starter and received US and Canadian patents for software control algorithms. In addition, he managed 600VAC variable frequency drive development for systems up to 700 horsepower, has extensive application engineering in motor controls, AC power system engineering simulation expertise for solid state motor controls and management in all aspects of synchronous three phase motors.
