    Rear Brake for a Trike

    Hello Brian, Its a "concept car" for me and would be intensively tested in close circuit before I make it street legal. I will try to follow the braking strategy that you suggested. I am concerned if the rear brake cylinder from motorbike will build enough pressure to lock the disc brakes...

    Rear Brake for a Trike

    Hello gentlemen, Thanks for your inputs. I would summarize the missing information: 1. Max Speed would be restricted to 80KMH. 2. From construction point of view very similar to...

    Rear Brake for a Trike

    Dear Community, I am designing a loader-trike. The full laden weight will be around 800Kgs. For rear axle, I am using some off-the-shelf parts from a small car with disc brake systems. These parts very basically placed in front-axle in that car. So I am just reversing the axles. For front I am...

    Alu Profile maximum hanging load?

    Dear Community, I am trying to build a structure using Aluminum Profiles using Item type standard. The structure is going to experience dynamic forces. My question is: If I connect two 40x40 in a T-Fashion using a 8 Nut with an automatic connector, what is the maximum load this structure would...

    Finding Torque vs RPM without Torque sensor Three Phase Induction Motor

    Hello Waross and other members, After getting inspired by your thoughts, I have decided to go for the following arrangement to measure my motor torque. My questions are: 1. Do you think this would work for a torque of 120Nm 2. Our motor has a max power of 30KW, now I was thinking that the...

    Finding Torque vs RPM without Torque sensor Three Phase Induction Motor

    Hello Guys, I love your answers and so the concept of Prony Brakes. I am willing to invest in the drum brake and a spring balance as Skogsgurra mentioned above. But if I understood the concept from Waross correctly then this setup measures the static torque. That means under 0 RPM, since the...

    Finding Torque vs RPM without Torque sensor Three Phase Induction Motor

    Hello Waross, Thanks for your valuable reply. I understand what you mean and also convinced that the experiment is based on lots of assumptions. As a background information, the application of the motor (15KW nominal and 30kW max) is in an electric car and we have a motor controller designed...

    Finding Torque vs RPM without Torque sensor Three Phase Induction Motor

    Dear community, For one of the projects which I am currently working on, I want to quantify my three phase AC induction motor in the following ways: 1. Find Torque vs RPM Curve 2.Find Efficiency vs RPM Curve Now since I dont have the industrial "Torque Sensor" to plot Torque vs RPM curves, I...
