They rotate the wheel either through an axial, inrunner, or outrunner rotor design, with either brushed or brushless commutator design. [18] Honda FCX Concept 2005 in-wheel motor with high-voltage wires in orange. Running high voltage outside the chassis can be avoided by using near-wheel motors, which have similar advantages to in-wheel motors.
In 2006, PML Flightlink demonstrated the Hi-Pa Drive in a series-hybrid car at the British Motor Show in London, using a Mini dubbed the "Mini QED" with its in-wheel motor at all four wheels. [1] Two other car manufacturers have also presented concept cars using this technology: Ford with a Ford F150 pick-up prototype presented at the 2008 SEMA ...
Concept (top view): In a vehicle, motors M1 through M4 drive respective wheels independently, possibly through respective gear arrangements. Individual-wheel drive (IWD) is an automobile design in which the vehicle has an all-wheel drive powertrain that consists of multiple independent traction motors each supplying torque to a single drive wheel. [1]
Super Handling-All Wheel Drive (SH-AWD) is a full-time, fully automatic, all-wheel drive traction and handling system, which combines front-rear torque distribution control with independently regulated torque distribution to the left and right rear wheels. This way the system freely distributes the optimum amount of torque to all four wheels ...
Parts of a rail system might use different voltages, with higher voltages in long runs between stations and lower voltages near stations where only slower operation is needed. A variant of the DC system is the AC series motor, also known as the universal motor, which is essentially the same device but operates on alternating current.
The most common wheel speed sensor system consists of a ferromagnetic toothed reluctor ring and a sensor (which can be passive or active). The tone wheel is typically made of steel and may be an open-air design, or sealed (as in the case of unitized bearing assemblies). The number of teeth is chosen as a trade-off between low-speed sensing ...
This may be initiated automatically when the Wheel Slide Protection system senses loss of adhesion, or the driver can operate it manually. Sanding may be connected to a computer system that determines the train's direction of travel and where the sand should be applied: either in front of or behind the trucks. In older locomotives there was a ...
The system uses twin electric motors installed in the rims of the nose wheels. [3] These motors are powered by the aircraft's Auxiliary Power Unit (APU). According to Aviation Week , the WheelTug system is projected to provide savings in ground turnaround time and increased aircraft utilization.
