1. ### How to calculate the stability and strength of a simple chassis?

Dear community, I am an electrical engineer trying to make my hobby four seater car. Being not a mechanical guy I am really uncertain of the chassis design that I have concepted though with the help of a friend we got some basic simulation running. My concept is to use a standard rectangular...
2. ### Gearbox explanation

The motor is AC motor similar to attached image. The application is in a small electric drive cart.
3. ### Gearbox explanation

Hello Baluncore The motor is a simple AC motor (is not shown in diagram). I want to connect this motor to the gearbox and therefore the shop told me that this is the gearbox they could offer me. Sure the information is not complete, thats why I want to understand basics before I confront them...
4. ### Gearbox explanation

Please ignore the blue line in the middle. Normally my motors spline should be inserted in it. And as a output I expect two splines with reduction where I could mount my cv drive shafts. This is a single reduction gearbox with a differential. Still I don't get the construction....
5. ### Gearbox explanation

Thanks for the video. What I am looking for is the setup in regards to the gearbox in the pic attached. Can you explain me the connections in it.
6. ### Gearbox explanation

Dear community, for my hobby project I found a gearbox online which shall be connected to a electric motor I have. I expect that the driveshafts with CV joints to be connected directly to this gearbox. Can someone explain me the construction as in how should the motor be connected and how the...
7. ### Calculating gear ratio from the motor's graph for an EV?

Dear community, For my electric vehicle project I want to select a gear ratio (single) of my gear box and send this information to the supplier. In order to calculate this ratio I thought of the following steps but am not sure and want some expert to recheck and answer my queries: 1. Calculate...
8. ### Calculating Power for a car, and relating it to the motor curve

Hello all, I am trying to build a simulation to understand what power is required by an electric car in order to accelerate from 0-50kmh. As per my understanding the total power required by engine is calculated using Total Power required at given velocity formula as stated below. I am...
9. ### Finding the Torque vs RPM curve for a 3-phase AC induction motor

Thanks for the reply. The motors are having a nominal of 15KW. We are coupling the motors on the jig. Normally there is an industrial torque sensor which one uses for detailed analysis. This unit is very expensive and thats why we want to proceed without it. So I just want to get your opinion if...
10. ### Finding the Torque vs RPM curve for a 3-phase AC 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...
