Plettenberg is well known in the model airplane world for its large and powerful electric motors that pull or push giant-scale models \u2013 sometimes half the size of their real counterparts \u2013 into the air.\u00a0 Brian Carpenter of Rainbow Aviation is even using them on his EMG-5 and EMG-6 ultralight aircraft<\/a>.\u00a0 Jean-Luc Soullier had two of them on an electric Cri-Cri<\/a>.\u00a0 His forum details that adventure and subsequent projects.\u00a0 These Predator motors weigh a little over four pounds and can put out 15 horsepower and up to 99 pounds of thrust with the right propeller.<\/p>\n

Going beyond their model motors, Plettenberg has bold thoughts to share about its new, bigger and less model-like units<\/a>, including their 150 kilowatt Nova series motor.<\/p>\n

\u201cThe guiding principle for the development of the Nova series was the creation and development of a completely new product and not the development of existing systems.<\/p>\n

\u201cCombining intelligently selected materials and components together with innovative, ground-breaking geometries made these unique actuators possible.<\/p>\n

\u201cHere, the experience of the high-performance models of sport, led in recent years to win multiple world titles, contributed to the development of engines and are from the 2013 season in the e-bike racing series TTXGP feed.\u00a0The NOVA 150 will be the drive to beat, because the experienced team at the world champion of 2010, 2011 and Vice World Champion 2012 racing season starts this with him chasing the title in 2013!\u201d<\/p>\n

Review of current racers in the TTXGP lineups do not reveal a bike with a Plettenberg on board, but that may change during the season.<\/p>\n

The Nova 15 looks like an apt possibility for ultralight aircraft use, weighing a mere 2.5 kilograms (5.5 pounds) and putting out 15 kilowatts (20.1 horsepower) and 30 Newton-meters (22 foot-pounds) of torque at 4,900 rpm when driven by 80 Volts.\u00a0 Plettenberg claims 92-percent efficiency for the Nova 15.<\/p>\n

Their Nova 30 produces 30 kW (40.2 hp) from five kilograms (11 pounds) at 120 Volts.\u00a0 It generates 105 Newton-meters (77.4 foot-pounds) of torque and can top out at 3,300 rpm at 93-percent efficiency.<\/p>\n

The 150, according to Plettenberg\u2019s web site, seems destined to be a challenger in electric motorcycle racing, putting out a very competitive 150 kilowatts (201 hp) from 11.5 kilograms (25.3 pounds) and 250 Nm (184.4 ft.-lbs.) of torque with 95-percent efficiency.\u00a0 A higher-voltage unit than its smaller brethren, the 150 pulls 350 Volts at full power.<\/p>\n

All are small for their output, compact pancakes ranging from 87 millimeters to 104.7 millimeters (3.42 to 4.125 inches) in thickness and from 124 mm to 310 mm (4.875 to 12.20 inches) in diameter.<\/p>\n

Finding most commercially-available units too big and heavy for its purposes, Plettenberg teamed with MST to develop two motor controllers that would match their \u201cself-imposed standards of quality and optimization,\u201d epitomized by their motors<\/p>\n

The smaller MST 140-200 controller weighs 1.3 kg. (2.86 pounds) and can handle continuous outputs of 30 kW and a peak power of 40 kW.\u00a0\u00a0 Its \u201cbig brother,\u201d the MST 400-400 weighs a bit more, 2.9 kg. (6.38 pounds) and can manage a continuous output of 120 kW and a peak power of 160 kW.\u00a0 It is equipped with an integrated water cooling.<\/p>\n

These are high-end motors compared to their model counterparts, the 15 kW model costing over $3,000 at current rates of exchange, with bigger motors probably proportionally more. \u00a0 As such, they will probably find a market for applications where light weight and power are more important than cost.\u00a0 In the aviation market, these are not \u201chigh-end\u201d at all compared to other powerplants available.<\/p>\n
