This also means the vehicle can park front-, rear-, or side-on to the kerb, and occupants can disembark straight onto the pavement without having to step into the road.<\/p>\n<p>The manoeuvrability enabled by the 360-degree steering system realized by Protean Electric\u00a0will allow for exceptional versatility on busy urban streets, and parking in tight spaces with absolute kerb-side precision, Protean Electric points out. Once stationary, the pneumatic ride height control of Protean360+ will enable the vehicle to \u2018<strong>kneel<\/strong>\u2019, dropping the vehicle entry-point to kerb level. This will afford stepless and virtually gapless ingress and egress for heavy or cumbersome loads or for passengers with impaired mobility.<\/p>\n<div class=\"aspect-w-16 aspect-h-9\"><iframe loading=\"lazy\" title=\"Urban mobility pods to be driven by  360-degree steering technology\" width=\"1778\" height=\"1000\" src=\"https:\/\/www.youtube.com\/embed\/LWOFTbqJtzI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<p>&nbsp;<\/p>\n<h2>Protean Electric. The motor? Inside the wheel<\/h2>\n<p><strong>Electric propulsion<\/strong> is provided by the <strong>ProteanDrive<\/strong> in-wheel motor. It consists of a <strong>permanent-magnet synchronous motor<\/strong> with an <strong>integrated inverter and a dedicated liquid cooling circuit<\/strong>, all tightly packaged within the wheel rim. A friction brake disc and caliper are packaged in the wheel with the ProteanDrive motor, complementing its regenerative braking capability.\u00a0The component\u00a0can apply positive or negative torque within milliseconds, meaning improved performance of ESC, ABS and traction control systems, which benefit safety, stability and stopping distances.<\/p>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6296 size-large\" src=\"https:\/\/www.sustainable-bus.com\/wp-content\/uploads\/2019\/07\/Protean360_internal-view-e1563958668773-1024x568.jpg\" alt=\"Protean Electric\" width=\"1024\" height=\"568\" \/>\n<h3>Protean Electric, the motor connected directly to the hub<\/h3>\n<p>The rotor of the electric motor connects directly to the hub, delivering torque from the motor to the wheel and removing losses in power transfer. The direct drive configuration is reflected in the high-torque, low-speed design of the ProteanDrive motor.<\/p>\n<p>The motor features an outer rotor to maximise torque; this outer rotor configuration allows the rare earth-magnets to be surface-mounted without retention features that would otherwise compromise performance, Protean Electric points out. Each ProteanDrive PD18 motor (to fit an 18-inch wheel) develops <strong>1,250 Nm<\/strong> (922 lb-ft) peak torque and 80 kW (107 hp) peak power.<\/p>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-6295\" src=\"https:\/\/www.sustainable-bus.com\/wp-content\/uploads\/2019\/07\/Protean360_pod-wheel-rotation-1024x512.jpg\" alt=\"Protean360+ protean electric\" width=\"1024\" height=\"512\" \/>\n<h2>Protean Electric getting ready for a new class of urban transport vehicles<\/h2>\n<p>\u201c<strong>Transport-as-a-Service urban mobility is gaining momentum<\/strong>, and with it the need for <strong>a new class of urban transport vehicles<\/strong>,\u201d explains <strong>KY Chan<\/strong>, CEO of Protean Electric, a former UK company recently taken over by\u00a0NEVS\/Evergrande.\u00a0\u201cWhether shared or private, for passengers or goods deliveries, human-driven or autonomous, these new vehicles will require new technologies to be fit for purpose.

The Protean360+ corner module intelligently combines cutting-edge, production-ready technologies.
