Q:Electric motor heating what happened?: The motor will heat up or even burn out the motor when the work time is too long

Q:The electric motor is broken. What's the reason?: 1.5 、 the no-load / load speed ratio of the motor is greater than twoTurn on the power, turn the handle, make the motor rotate at high speed and no load, more than 10s.When the speed of the motor is stable, the maximum speed of the motor is measured at N1 with a hand-held speed / speed meter.In the standard test conditions, traveling above 200m distance, began to measure the maximum load speed of motor N2.Load / no-load speed ratio of =N2 / N1When the motor no-load speed / load ratio is greater than 1.5, indicating the motor magnet demagnetization has been quite severe, should replace the motor set inside the magnet, in the process of practical maintenance of electric vehicles in general is the replacement of the entire motor.

Q:Electric vehicles in the process of the exercise is sometimes at constant speed motor suddenly issued a "buzz" and not! It seems that the electricity has been cut off and accelerated again! Sometimes the speed brake motor is a "buzz" sound great! The whole car will ring! Sometimes it happens, and sometimes it's normal! What's the matter? Never been like this before! Is the motor running into water?New problems have been found this evening! When the power is half used, the voltage indicator refers to the yellow line area! When I put the brakes in the high speed I found this pointer back to the green line area! Back to the Yellow line! That's what happens when you brake! I wonder what this is about My car doesn't have anti charging function! How could it be like this? That's what you found tonight! I didn't see that before! Please expert pointing! Thank you My battery is dry and new! Is there something wrong with the battery?! Or something else?: The motor only a sound, it is definitely not the water, if the water so that the sound would have been some trouble

Q:Engine for electric cars?Depending on the environment and frequency of use, the form is different: Depending on the environment and frequency of use, the form is different. Different forms of motor, its characteristics are not the same. At present, permanent magnet DC motors are widely adopted in electric vehicle motors. The so-called permanent magnet motor, refers to the motor coil using permanent magnet excitation, and do not use coil excitation mode.

Q:Why is the motor of electric cars reversed?: The electric motor reversal hall lead wiring dislocation motor phase dislocation or brushless controller, method of correcting inversion is: if the brushless motor shows that the phase inversion, brushless controller and brushless motor is matched

Q:How to measure the electric motor's good or bad?: If normal, the motor control is good. In addition, the line of three thick points is the motor line. As long as there are many ohms resistance between the line and the line, and the difference of the resistance value is very small, the motor can be judged well.

Q:How to choose the motor of electric vehicle?: There are two kinds of electric bicycles: brushless and brush motors. At present, brushless permanent magnet motors have the tendency to replace brush motors. The controller must have the functions of stepless speed regulation, undervoltage, overload and power-off protection, and also has an electric quantity display device. Charger should have automatic equalization charging function, generally observed from the plug for the four core, can be achieved after charging three sets of battery voltage consistent, so as to improve the capacity of the battery.Battery (storage battery) is the key part of electric vehicle. At present, all manufacturers are using lead-acid battery maintenance free, but because of the different formula, the service life is not the same, some seven or eight months, some year or even longer. A car battery market price of 300 to 450 yuan. The longer the service life, the better for the user. It is reported that there are new nickel hydrogen hydride, nickel cadmium battery came out, but the price is more than 3 times the lead-acid battery, but because of its light weight, long service life.

Q:Method for operating motor of electric vehicle: In the electric bicycle industry, the motor generally refers to the motor assembly, including the motor, heart, deceleration mechanism. Below we are talking about electric bicycles are motor assembly.I. dismantling of the motorBefore removing the motor, the motor and the controller's lead should be pulled out first, and the corresponding relationship between the lead color of the motor and the lead color of the controller must be recorded. Before opening the cover of the motor, the operating area shall be cleaned so as to prevent the sundries from being sucked into the magnetic steel in the motor. Mark the relative position of the end cap and the wheel hub. Attention: be sure to loosen the screws in diagonal order so as to avoid the deformation of the motor housing. The radial clearance between the rotor and stator is called air gap (air gap), and the air gap of the general motor is between 0.25-0.8mm. When the motor is removed and the motor is removed, it must be assembled according to the original cover mark so that the phenomenon of sweeping after the two assembly can be prevented.

Q:Electric motors, the greater the number of watts, the better, or the smaller the better: Electric motors, the number of Watts as much as possible, the greater the number of watts, on behalf of the greater power, you can travel to higher speed, and now looking for high power EMU is the mainstream, but also technical difficulties.

Q:How much is the electric motor of 48 volt electric car?: There is also a difference in the price of an integral wheel and a spoke wheel. Generally no more than 500, I hope it will help you.
