Q: 1: for example, a 1200W controller, while controlling 2 550W electric vehicle motor, OK, that is, the 2 motors in parallel, the battery components using 60V20-30A.. I just want the 2 rear wheels to be driven at the same time with 2 wheels with motors2 or 2 controllers respectively control two motors, the two controller acceleration line, reversing line, line level, battery power line and all together, thus to control the acceleration and speed reversing gear with a throttle, a reversing switch3: the car's lowest gear seems to be more than 10KM/H speed, there is no way to increase a gear, the speed control at the maximum 5KM/H, how to control, you can control separately4: four wheel electric car rear wheel drive, the maximum speed at 40KM/H, turn the corner when the speed down, do you want to install differential?: Four wheel electric car rear wheel drive, the maximum speed at 40KM/H, turn the corner when the speed down, whether or not to install differential,?Answer: can not be installed, installed after the security role, but will increase the consumption of electricity to re accelerate and increase the cost of power when the brakes are not recommended to install uniform deceleration (otherwise it would like the car suddenly on the clutch, inertia speed)Recommendations: this modification cost is too high is not the actual consideration of motor with gear, such as large torque point, stable running, the cost will be more than you plan to save money price, brakes can also save money, more stable!

Q: How to select a field effect transistor for brushless DC motor controller for electric vehicle: Hello.- * 1, rated voltage of 48 V, the minimum pressure pipe selection should be 2 times of the rated voltage, so that the field effect is greater than, equal to 100 of the tube can be V.- * 2, motor starting current is 5 to 7 times the rated current of the electric vehicle, if the rated load current of 15 A, then the rated current pipe should be above 105 A, can run reliably.- * 3, because the output current of the power tube is larger, can use multiple power tube parallel operation mode. 3 40 A tubes (or other combinations) can be selected, and the type characteristics of the pipe shall be consistent. In fact, the high-power product controller is also used in parallel with multi power tubes.

Q: What is the general pulling force of electric motors?! And other parameters? Consult your teacher: General with 36 volts 12 ah battery quality brand-name electric bicycle mileage about nominal 45~60 km, while individual manufacturers nominal will rise to 70~80 km, which is suspected of false propaganda. Because of this nominal value, the efficiency of the motor is about 40% higher than the efficiency of the motor used in the brand factory. If a brand efficiency of motor factory production in the above described working state is 75%, the motor efficiency is 70~80 km nominal manufacturers has reached more than 100%, which is obviously impossible, this point to remind the consumers attention:

Q: I want to buy an electric car, but I don't know whether it's good for 48V or good for 24V: Generally speaking, electric vehicles use batteries as their energy source, and through the controller, motor and other components, the electric energy is converted into mechanical energy movement, so as to control the current size and change the speed of the vehicle.

Q: How do you change electric cars, motors, Holzer?: After opening, you will see 3 Holzer on the coil, usually switch Holzer (split pole switch, such as OH44E, and bipolar latch, such as: OH41, or OH41F, which is determined by the motor phase. Depends on the original unipolar, and now for the unipolar, the original bipolar is now replaced by bipolar). The best 3 are all changed.All Holzer has to go through the controller, Holzer's good controller is broken, and the car has a problem

Q: How to judge the quality of motor vehicles?: (2) brushless low speed motor. The non reduction gear device has the advantages of no maintenance and no noise. But the controller is complex, the starting current is large, and the overload climbing ability is poor.(3) the low speed motor with brush and no gear reducer has the advantages of simple structure, low cost, poor ability of starting uphill and overload, and large power consumption.

Q: My electric car just bought less than a month, when I bought a car, I think the motor sound is big, but people who buy cars say no problem. But I am still a little worried, I hope you help see, the situation is as follows: as long as the starting motor, there is noise, glide when there is no sound. Note that the motor starts much larger than the other motors. So I would like to ask you whether it is a quality problem or what is the problem. Thank you again: A general motor high power sound is relatively large, the motor and the controller you must be 500W, but you don't have to worry about, this is completely normal, the stator of the motor is energized when the electromagnetic coil, will produce a sound, the greater the power, the greater the sound.

Q: How to measure the power consumption of motor vehicles?: If it is current, the current electric vehicle motor power, most of the 350-400w, the working voltage 48V mostly; full load operating current should be about 7-8A.Electric vehicles, that is, electric vehicles, also known as electric cars. Electric cars are divided into alternating current electric vehicles and direct current electric vehicles. Generally speaking, electric vehicles use batteries as their energy source, and through the controller, motor and other components, the electric energy is converted into mechanical energy movement, so as to control the current size and change the speed of the vehicle.

Q: Brushless electric motor brushless motor and brushless gear motor which good? What are the advantages and disadvantages? Which is efficient?: Maintenance is also very simple, just open the motor, add grease to the gear. Brushless gear motor performance is better than brushless brushless motor, in power to get more torque on the smallest power, improve climbing, reduce the burden on the battery. Multi choice brushless motor with brand electric vehicle. You will now choose brushless brushless motors!

Q: The motor by hand to turn the speed of great resistance, electricity will only move not to, when I put the ash line disconnected, motor operated by hand is very light, when disconnecting the gray line by hand to make the motor rotate speed, then it will turn, what is the reason?: Phase line short-circuit motor will die, the controller's power line breakdown line will short-circuit!!
