00:22 What is the biggest problem in the market of small electric transport?
00:51 How to solve this problem?
01:12 What do buyers of electric scooters need?
01:26 Does the maximum torque depend on the power?
01:38 What is power?
01:54 We experiment with setting the phase and battery current of the electric motor.
02:26 We put the phase current 7 times more than the battery current, what happened?
02:41 What does the torque of an electric motor depend on?
03:00 We show the principle of operation of the BLDC electric motor.
03:50 The difference between phase current and battery current.
04:14 About one of the most important functions of the electric motor controller.
04:39 What does the speed of an electric scooter depend on?
05:25 Why does the torque of the electric motor decrease with increasing speed?
05:49 How to get the maximum torque of an electric motor in the entire range of revolutions?
06:38 Why is it better to go under the hill at a higher speed? The efficiency of the electric digger.
07:14 What is the most important characteristic of an electric motor
07:38 Why are batteries with a voltage of up to 400V installed in electric cars?
08:03 What does the rated power of an electric motor depend on?
08:37 How to find out the rated power of an electric motor if you can measure its stator?
08:50 The difference between nominal and long-term power.
09:17 How many times is the peak power higher than the nominal?
09:53 A motor rated at 1000W is often sold as 3000W.
10:30 Features of conventional controllers used in inexpensive electric scooters.
12:14 Why shouldn't you tinker with a shunt to increase the power of the controller?
12:42 Advantages of a vector control (FOC) controller
14:12 How to know which controller to use for a certain electric motor?
15:35 How to determine the real battery capacity without any devices.
17:33 How to determine the long-term and peak power of an electric scooter?
17:56 How to determine the torque of an electric scooter?
19:08 How to avoid deception with characteristics when buying an electric scooter?
This video is not a scientific report. The theory of processes that occur is much more complicated and requires many times more time to explain. Our goal was to explain the existence and importance of such a quantity as the phase current to an ordinary viewer as simply and briefly as possible.
