Electric Vehicle Motor Proliferation Spurs Huge Market, Finds IDTechEx Research
BOSTON, February 27, 2019 (Newswire.com) - Traction motor sales grow faster than electric vehicle sales because small vehicles, such as mobility for the disabled, have two motors. IFEVS has put two in microcars for four-wheel drive. In larger cars, two motors is now commonplace for economy, performance, four-wheel drive, vectored steering and attack survival. Audi E-tron GT’s two synchronous motors, one at the front and one at the rear, produce a collective 300kW 664 N.m power output for 0-62mph in 3.5sec, top speed 149mph. The quattro permanent all-wheel drive gives torque vectoring. Two motors are in the following existing and planned cars: BMW X3SUV, Aston Martin RapideE, Mercedes EQC, Tesla S, X and Y. The new IDTechEx Research report, “Electric Motors for Electric Vehicles: Land, Water, Air 2019-2029” has the analysis and appropriately comprehensive forecasts.
Avid offers so-called portal two-motor systems for buses and trucks: BYD does something similar near-wheel with its own technology for its buses selling at 10,000 yearly levels. Indeed, many in-wheel four-motor cars, trucks and buses are imminent: Nikola trucks have six. The Solaris Urbino pure electric 12m bus has two axle motors. Little wonder Dana now offers all the multiplier options.
Dr. Peter Harrop, chairman of analysts IDTechEx, advises, “Using two motors allows for improved vehicle dynamics through torque vectoring which can improve traction, reduce cornering loads and reduce wheel slip. This results in reduced tyre wear in a delivery truck application and stops shredded tires previously suffered when performance cars perform. For construction vehicles, Huddig says its new loader due 2020 does not use the typical slip steering that rips up city roads, it uses vectored steering that damages nothing.”
IDTechEx finds that several new cars, trucks, military and off-road vehicles in construction, agriculture and mining even have four to six in-wheel or near-wheel motors, but two e-axles is also a popular new choice. The IDTechEx report “Electric Vehicles for Construction, Agriculture and Mining 2019-2029” gives more. The IDTechEx Show! in Berlin on 10-11 April 2019 has an EV motor session in its conference, “Electric Vehicles: Everything is Changing” and master classes on motors and allied EV subjects.
