FAQ

How to check the controller and motor of electric vehicle?

When the brushless controller of the two wheeled electric vehicle is powered on, the input and output voltage of each lead is detected. The two is a thick line power line 48V, three RGB thick line is the main line voltage to the motor is 48V

Have the same type, electric bicycle production in different periods, because the batch is different, there is a large rear wheel motor, the appearance of area almost doubled, but the motor parameters are similar, the electric car the other configurations are the same, the price is the same as.Excuse me, should we choose motors or motors?Please explain the reason for the points, oh, thank you!They're all 250W. They're all Brushless

Add, determine directly differentiate brush motor and brushless motor: the motor rotates, if the motor rotates pros and cons are very easy is the brushless motor, if it is a laborious effort being reversed brush motor, motor brush body is very small, brushless generally larger, brushless 3 line 5 line Holzer

How many motors are there?

The working voltage of the electric motor is different from the machine manufacturer and model, and the working voltage is different. There are 48 volts, 50 volts, 60 VOLTS, 64 volts, 70 volts, 75 volts, and so on. Usually, the speed of the electric vehicle depends on its working voltage and current. That is to say, the working voltage and the working current are in direct proportion to the speed.

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)

Is there any difference in the size of electric motors?

Hello. The size of the motor has no curvature. The wattage of the motor is different. Hope to adopt

Electric car boring how to do?

2, look at the current battery, which is after the battery is full, the road riding switch to the most high-grade, high capacitance pointer will not rotate well should be in full power when not moving, if the current is not stable, the battery may be already aging out, to be replaced or battery activation it would take hundreds of bills.Batteries are life, and often use about 2 years; and there is not to use electricity deficit (jump off) before charging, so that too much damage to the battery, to charge in time; do not overcharge. (it's more likely)

Method for overhauling motor of electric vehicle

When the motor is running, it has mechanical collision or mechanical noiseNo matter the high speed motor or the low speed motor, there should be no mechanical collision or discontinuous and irregular mechanical noise in the running of the load. Different forms of motors can be maintained in different ways.4, the vehicle mileage is shortened, the motor is weakThe reason of short vehicle mileage and motor fatigue (commonly known as motor boring) is complicated. But when we exclude the above 4 kinds of motor fault, generally speaking, the vehicle fault continued short trip mileage is not caused by the motor, and the attenuation capacity of the battery charger, filling electricity, controller parameter drift (PWM signal does not reach 100%) etc..5 brushless motor phaseThe absence of phase in brushless motor is caused by the damage of the hall element of brushless motor. By measuring the resistance of the output of the hall element relative to the hall wire and the lead of the relative hall power source, the comparison method is used to determine which Hall element is faulty.In order to ensure the commutation position of the motor, it is generally recommended to replace all three of the hall elements at the same time. Before replacing the hall element, it is necessary to make sure that the phase algebra angle of the motor is 120 degrees or 60 degrees, and that the three Hall elements of the phase angle motor are in parallel with each other in 120 parallel positions. While the 60 DEG angle motor, a Hall element in the middle of the three Hall elements is placed in the position of 180 degrees of reversal.

Can electric motors generate electricity?

Nowadays, brushless DC motor (BLDC) is commonly used in electric bicycles, and the rotor is the permanent magnet,
