Permo-Drive Technologies Ltd What is the Regenerative Drive System (RDSTM)? Permo-Drive has created an intelligent hybrid hydraulic system for urban commercial vehicles which saves fuel and therefore reduces carbon emissions and other pollutants. These vehicles are significant fuel users and polluters in every country. The RDS technology captures energy normally wasted as heat during braking and re-uses the same energy to accelerate the vehicle, thereby reducing fuel and emissions. The RDS comprises a hydraulic pump/motor connected to the driveline, accumulators, reservoir, sensors, hydraulic control manifold and a programmed software controller.

Hydraulics - Hydraulic Launch Assist With Eaton Hydraulic Launch Assist (HLA) systems, you can improve fuel economy and reduce emissions in vehicles that operate in continuous stop-and-go duty cycles, such as refuse trucks and buses. These hybrid hydraulic systems supplement conventional vehicle powertrains in two ways: Regeneration and Launch Assist. Regeneration How to Lace an E-Bike Hub Motor Wheel This article is primarily aimed at guiding a less experienced bike mechanic through rim replacement on an electric bike hub motor. It also can be used as a guide for those wishing to do their own wheel build on a conversion project. I don’t pretend to be a wheel expert. For detailed information on the subjects in this article, go to the Sheldon Brown website. This is a wheel building clinic for hub motor electric bikes.
DK LABORATORIES Special Thanks: AMC saved the day on this build, donating an AZB60A8 three-phase servo drive. It preformed phenomenially, even with some interesting riders, smashing between forward and reverse and bouncing all around. Not only did it survive the electrical loading, the shock-and-vibe from this application is enormous! Hybrid Technology Engineered For Commercial Fleets Request a Demo What Is A Hybrid Conversion? A hybrid conversion is a cutting-edge technology designed to transform your existing vehicle, or a new one via ship-thru installation, into a hybrid electric vehicle. XL Hybrids system is designed to work on the most popular Class 1-3 fleet vehicles, including cargo/utility/shuttle vans. By adding hybrid powertrains to your fleet, you can cut fuel costs, reduce your exposure to fuel price fluctuations, and reduce emissions. Why wait?
The Ebikingnow Dynamometer - ebiking now Dynamometers (or Dyno for short) are awesome devices; they provide consistent feedback and results of a motors performance and characteristics. The fundamental principle of a Dyno is relatively straight forward, where output data calculated is from the rotational speed of an object multiplied by the torque experienced by that object. On my Dyno, I am spinning up a direct drive hub motor that is free to rotate while connected to a torque arm and load cell to measure output torque. Kitmotter! archive Kitmotter, the concept that never quite was. Originally, I built Kitmotter 0001 to be used on a little display stand in order to show the concept of laminated (coarsely-layered, anyway) rotors for potential hub motor or custom BLDC motor applications. The concept is a direct knock of the laminated hub motors of B.W.D Scooter which was the first to explore the idea of using waterjet-cut steel rings with magnet “indents” allowing for easy placement and waterjet-cut plastic (or metal) endcaps – basically allowing a brushless motor to be constructed without any intensive machining work. At least, it gets rid of the need for a large machine to turn the steel rotors that my designs all feature – I can make a whole post about all the random workarounds that we’ve tossed around for building whole motors.
Millbrook Proving Ground We have a number of production facilities for prototypes through to large volume production. All prototypes and specialist ‘one-offs’ are developed within a high security (government approved) workshop alongside our own engineering designers and manufacturing engineers. As an example, following design approval, series and large volumes are manufactured in a second larger secure workshop where ‘station’ build techniques construct the vehicle in eight distinct stages. Torque Vs Wheel size - ebiking now Motor torque and what the rider feels can be drastically different from one another and depends on several factors. Motor torque is in the form on Newton-Meters, which represents the amount of force that is applied by a rotating member at exactly 1m from the axis. Now, on a bicycle tyre, the distance from the centre of the wheel to the tire tread is our distance, and for a 26” bike is not 1 meter but a mere 330mm! That means that the resulting force of a motor that is rated to 100Nm would be exerting 303 Newtons at the road on a 26” wheel and 100 Newtons if the wheel radius was 1m (hypothetical of course). This is why a motor laced to a 20” wheel will feel like it has more acceleration than a motor laced to a 26” wheel, because it does!
