MagniX
magniX is an electric motor manufacturer for electric aircraft, wholly owned by Singapore investor Clermont Group. The company is headquartered in Everett, Washington, United States. History. The company was founded in 2009 in Australia to research various technologies for electric motors. In 2017, it developed a motor that became their prototype and led to pivoting the company to focus on Electric Aviation and move its headquarters to Redmond, Washington. The magni5, its original prototype electric motor, was developed in 2017. In June 2018, magniX publicly stated plans to fly an electric Cessna 208 Caravan with a motor for up  to an hour, by August 2019. By then, the company's magni5 electric motor could produce peak at 2,500 rpm at 95% efficiency with a 53 kg (117 lb) dry mass motor, having a 5 kW/kg power density. The magni5 competes with the , Siemens SP260D for the Extra 330LE. By September 2018, a electric motor with a propeller had been tested on a Cessna iron bird. The Caravan was expected to fly by the fall of 2019 and by 2022 magniX estimates electric aircraft could fly up to by 2024. The motor ran on a test dynamometer for 1,000  hours. The iron bird is a Caravan forward fuselage used as a test bed, with the usual PT6 turboprop engine replaced by an electric motor, inverter and a liquid-cooling system, including radiators, driving a Cessna 206 propeller. The production motor will produce at 1,900 rpm, down from the test motor's 2,500 rpm, allowing the installation of the propeller without a reduction gearbox. By April 2019, the magni250 375 hp (280 kW) was offered for the Eviation Alice as a second power option after Siemens 260 kW motors, as magniX had accumulated over 1,500 hours of ground tests in  Redmond and Australia. Beaver conversion. By then, magniX partnered with Harbour Air to electrify its entire fleet: the first converted aircraft was to be a DHC-2 Beaver serving as the test prototype for the magniX motor, energy storage, and control systems. On December 10, 2019, the eBeaver flew for the first time. Low energy density but proven lithium-ion batteries filled the cabin and took the prototype to its maximum gross weight to provide enough energy for a 15 min flight with a 25 min reserve. The magniX magni500 electric motor used in the Harbour Air electric de Havilland Canada  Beaver weighs and develops In contrast, the Pratt & Whitney R-985 Wasp Junior SB it is replacing has a dry weight of , not including oil, and produces , more than halving the weight, while nearly doubling the power - a saving in this case that can be transferred toward carrying the difference in additional batteries. Caravan conversion. The first flight of the modified Cessna 208B Grand Caravan was completed at Grant County International Airport on May 28, 2020. The eCaravan is powered by a motor and a , 750V lithium-ion battery. Its 30 min first flight consumed $6 worth of electricity, needing  30-40 min of charging. The magni500-powered variant can fly with 4-5 passengers while keeping reserve power, and aims for a certification by the end of 2021, hoping to operate 100-mile flights with a full load of nine passengers with better batteries. In January 2021 the company announced that they will be moving their headquarters from Redmond to Everett, Washington, with plans to relocate all of their Australia operations there as well.
