Electric Motorcycle Factory Shares The Importance Of Motors
The electric car motor is like the “heart” of the electric car. The same set of 48V 20AH lead-acid batteries, good quality and high efficiency motors can run 45-55 kilometers, so you must pay attention to choose high-quality accessories when buying electric cars. So Electric Motorcycle Factory teaches you how to distinguish the advantages and disadvantages of electric vehicle motors?
Since the motor is sealed, if it is fundamentally judged whether it is good or bad, it needs some external tools, such as a multimeter. In addition to using professional tools, you can also judge from appearance materials and general performance. The above methods can be simply summarized as follows: one look, two listen, three touch, four detection.
A look: look at the shell. The good motor made by the outer plating is generally brighter, and the refurbished machine is gray and dim. Look at the trademark of the motor again. Generally, the larger manufacturers value the brand development, which is a manifestation of brand quality. Finally, you can see whether the motor has 3C certification, and motors that meet industry specifications will also be more guaranteed.
Second touch: touch the temperature. After the motor stops, consumers can use their hands to sense the temperature of the motor. The lower the temperature, the better the heat dissipation of the motor and the better the performance.
Three listening: listening to motivation. During the test run, consumers can check whether the power is sufficient when starting under load. If the power is not sufficient, it is likely to cut corners on the motor coil.
Four detection: detection resistance.1. Check whether the AC three-phase motor is good or bad. A 500V shake meter is enough. The insulation resistance of the wires on the three terminal posts to the motor housing is above 0.5M Euro, which means that there is no short circuit to ground.2. Multimeter test: measure whether the resistance between A/B/C three phases is equal. The larger the numerical difference, the worse the motor performance. And the greater the motor power, the smaller the resistance value! But the three-phase can not be 0 ohm, unless the motor is particularly large, such as more than 50KW, but this current electric vehicle application can be said to be no.
