accent was a problem, rest.. the video is good

Keep it up sir...its something goid

Good info video

great video, very helpful

Well educated👍🏻

great. simplicity is the best

Bhai, speak normally , don't try to put unnecessary acsent.

Does this power output for the motor mean it can start it from 0 speed? Shouldn't you take in consideration the static friction force with u(greek miu) = 0.7?

Hello mam I have seeing many videos in UR channel. Man I am having a bicycle gearless 36volt 360 watts hub motor in my home and I have not used it for many years. After seeing many KZread channel I have come to know that future is EV. Now I am planning to rebuild that vechical to run it. In my old ebicycle controller and many other parts are rusted and controller is not working & checking the hub motor with multimeter the motor terminals are in good condition and talking about hall sensor I don't know about it. It's working are not how can I check that My confusion is that is it good to buy a full set ((Hub motor, throttle & controller)) to fit in my cycle or can I restore my old hub motor with a new controller and the throttle only in my bicycle to run it. While talking about battery I have built a new one for my bicycle . please give replay I need your help thank U

Let's talk about Benling Aura model. Motor power: 2.5KW Battery: 72V, 40AH. max speed is 60kmph, so roughly peak power needed would be around 4KW. Pls explain how to get peak power as the OEM is nowhere telling about peak power and only talks about nominal power of 2.5kw. Very very informative video, Thanks 👍

The actual power depends on how much current the motor controller is sending to the motor. I couldnt find the rated current of the controller on this scooter so the only other way to tell is by using a current meter or shunt while riding it.

Sir if I'm using individual hub motor for Four wheel drive car then i can divide total motor power by 4 right?

Sir Is this calculation only for bldc motor? Can we use this equation for pmsm or ac induction motor ?

Sir Can you share research paper/literature review related to all these calculations

Good day Sir, I have a question. When you say a 100 watt brushless dc motor, does that mean input power or output power? I have a brushless motor. I calculated the values of the current drawn from the battery, the thrust and the speed. I want to calculate the power value to say that the motor has such a capacity.

In Motor manufacturer specification, the given power is output power of motor. Example: A 250 watt bldc motor means, 250 watts continuously it can deliver as output. Input power of motor = Voltage × current consumed by motor. Efficiency = (output power/input power) ×100%

how to calculate voltage for particular motor requirment?

Is this power requirement without gearing?

Sir, I sent you an email for the values I calculated and I want the efficiency and output power

Hi can you make a video on what battery sizing required to power a car ..

Calculate your requirements using formula given in video

Why you put angle 0 degree (flat surface) in F gradient. It will always give 0.

But the scooters used in electric vehicle are only 3 KW mac ...can you elaborate on this

If you want a motor that can achieve a certain acceleration, the rated torque is going to be the best indicator of that. (granted were talking about hub motors and that the motor can achieve the top speed) My 1500w motor that has about 42N.m. of torque will accelerate to around 56kph in about 6 sec.

Source??

sir consider if slope or gradient angle is 30 degree then what will be the value of F gradient and what is the value F total???

Hello! I think you forgot to multiply rolling resistance coefficient by the number of wheels on vehicle

@AllAboutEvehicles

2 жыл бұрын

Rolling resistance is a function of gross vehicle weight....so no need to multiply the number of wheels in the vehicle.

Bhai agr fake accent use nhi krta fir bhi video acche aur informative hote..🤦🏼‍♂️

Dear Pak, Whether this 5.5 KW power indicates rated power of Motor? How peak torque, peak power, rpm are plays further role in E-power train? Also how to choose 'rated voltage' of motor for given KW of motor? Whether 30V motor is best or 48V motor is opt for our vehicle?

Top speed 80kmph and acceleration 4 seconds are initially assumed values. This video is all about motor power calculation for this 80kmph speed. If you want to change the speed and acceleration, u can follow the same formula and calculation given. The final answer of motor power will be varied accordingly

wtf dude this is nothing different than regular force acting on a regular vehicle

Everything's good but your accent. Unbearable!
