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 ...
Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. [1] [2] [3] They can be used on small vehicles such as ride-on lawn mowers and motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high.
Human-powered transport is the transport of person(s) and/or goods using human muscle power.Unlike animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming, as well as small vehicles such as litters, rickshaws, wheelchairs and wheelbarrows.
The Honda HPE60, an electric power-assisted wheelbarrow, was produced in 1998. [42] [43] Power-assisted wheelbarrows are now widely available from a number of different manufacturers. Powered wheelbarrows are used in a range of applications; the technology has improved to enable them to take much heavier loads, beyond weights that a human could ...
Puncture resistance denotes the relative ability of a material or object to inhibit the intrusion of a foreign object. This is defined by a test method , regulation, or technical specification . It can be measured in several ways ranging from a slow controlled puncture to a rapid impact of a sharp object or a rounded probe.
A ZQDR-410 traction motor (the large, dark component on the axle with small ventilation holes) A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.
Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.
A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.
