A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

An electric wheel hub motor car was raced by Ferdinand Porsche in 1897 in Vienna, Austria. He developed his first cars as electric cars with electric wheel hub motors that ran on batteries. [15] A racecar by Lohner–Porsche fitted with four wheel-hub motors debuted at the World Exhibition in Paris in 1900. Alongside it a commercial model was ...
The hub motors are licensed from Elaphe Propulsion Technologies, a company based in Slovenia. [38] Each in-hub motor was expected to weigh 70 lb (32 kg), which increases the unsprung mass , but Lordstown CEO Burns was confident the suspension and software being developed for the Endurance would overcome these challenges.

The rotating shaft of the motor was also the axle for the wheels. In the case of French TGV power cars, a motor mounted to the power car's frame drives each axle; a "tripod" drive allows a small amount of flexibility in the drive train allowing the trucks bogies to pivot. By mounting the relatively heavy traction motor directly to the power car ...
The first application of the Volkswagen W12 was the 2001 Volkswagen W12, a mid-engined concept car which set the 24‑hour world endurance record in 2001 with a distance of 7,085.7 kilometres (4,402.8 mi) and an average speed of 295 km/h (183 mph). The first production car to use the W12 engine was the 2001 Audi A8 (D2). [4]
[citation needed] The lack of spokes or a traditional hub also allows for more space, which can be used to more easily package a hub motor. [ 2 ] While Franco Sbarro was the first to replace vehicles' conventional wheels with hubless wheels in 1989, [ 1 ] monowheels , which are similar in practice, predate Sbarro's hubless-wheel vehicles by ...
Blakely Auto Works (also called Bernardi Auto Works in later years) was a manufacturer of automobiles and of kit cars, working from premises located in a series of US midwest communities, including Princeton, Wisconsin, in the 1970s and 1980s. Blakely produced several kit car models, the Bantam, Bearcat, and Bernardi.
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.
