December 12, 2008: Benchmark RPM Goal Achieved
The E-Flight design team has reached a major milestone in the development of the E-Flight Electric Powerplant System’s Main Controller Unit (MCU) and Integrated Motor and Switching electronics (IMS). The E-Flight design team has been running the system at high voltage and amperage power inputs with a large bank of lead-acid batteries, simulating power levels… Read More
November 28, 2008: System Development and High Power Runs
The E-Flight design team has been steadily making progress on the electric motor and controller systems. The E-Flight Electric Motor is being run at increasingly higher power settings using a ground test bank of lead acid batteries (see video at right). As expected, development of the Main Controller Unit (MCU) and Integrated Motor and Switching… Read More
April 2, 2008: First Runs of E-Flight Electric Motor
A prototype AeroConversions E-Flight Electric Motor was first run in the fall of 2007 at low power using simple computerized commutation software. Since then, the prototype Hall effect sensing system for the motor has been built and tested, and the prototype E-Flight Electronic Motor Controller has been built and is currently being tested and refined….
