Q:Holzer component model of electric vehicle: Since you can disassemble the motor, there is no damage to the motor has been good, and the electric car accessories shop selling Holzer is not a model, points anti suit, can be installed to 60120. degrees

Q:Digital frequency conversion power generation type electric consult professionals now on the market that is true (such as Ji'nan Qingqi), established the principle of power generation, can have much effect.Recently, I would like to buy an electric car, please choose which type of motor (brush or brushless, tooth free, high-speed or low-speed), higher cost performance, what the configuration of the battery more durable?. Thank you: The rotor is generally made of laminated silicon steel sheets, and the enameled wire is wound between the two grooves of the rotor core (three slots with three windings), each of which is welded to the metal plate of the commutator.The brush is a conductive component connecting the power and rotor windings, and has two performances of electrical conduction and wear resistance. The brush of permanent magnet motor is made of single metal sheet or metal graphite brush and electrochemical graphite brush.

Q:What about the motor lock of the electric car?: Your one is not the motor lock, it is the brake lock. Very simple.Find a live wrench for 450 and clip the lock from the top or bottom with a wrench

Q:How to remove the electric motor, what should pay attention to ah?: Before 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, it shall be clean as a site 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 so as to avoid the deformation of the motor housing. The radial clearance of the rotor and the stator of the motor is called air gap (air gap), general motor air gap between 0.25-0.8mm, after the completion of the demolition motor eliminates motor fault, must be on the original cover mark for assembly, which can prevent the two assembly after sweeping phenomenon.

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:Electric car Holzer bad what symptom?: 3, Holzer motor broken (3 in all), the motor does not turn or turn the weak or abnormal sound (CACA), non professionals do not open, especially not open, because will damage the motor and water, if must be open to open whipped (because it has a strong magnetic force. Use a motor inertia open). Repair bicycles are generally open, it is best to find them.When you open it, you'll see 3 Holzer on the coil, usually switching Holzer, such as: OH44E, OH41, or OH41F. The best 3 are all changed.I hope I can help you!

Q:Electric motors, the greater the number of watts, the better, or the smaller the better: Machinery (Electric), commonly known as "motor"), refers to an electromagnetic device that converts or transfers electrical energy according to the law of electromagnetic induction. In a circuit, use the letter M (the old standard uses D). Its main function is to generate driving torque, as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function is to convert electric energy into mechanical energy.

Q:Can electric motors be refitted to speed up?: Can electric motors be refitted? Speed: the speed of an electric motor has nothing to do with brushless motors. Speed is related to the controller (inverter). The brushless motor of an electric vehicle is a three-phase AC synchronous motor whose speed is determined by the frequency of the controller (three-phase AC inverter)

Q:What kind of motor is an electric motor?: In addition, the switched reluctance motor also has great potential as an electric vehicle power, because the switched reluctance motor is lower cost, more reliable structure, and has a very good speed control ability. On the other hand, the efficiency and power density of switched reluctance motor is no worse than that of induction motor (of course, there is still no He Yongci motor ratio), and torque ripple and noise are also the weakness of switched reluctance motor

Q:How do you see the size of electric motors?: First of all, make sure that your electric vehicle controller is matched, with unlimited speed and current limiting device. If the controller can not meet the power of 800W, then it is useless to change the motor only.
