The lack of phase in brushless motor of fat tire electric bike is caused by damage of Hall element of brushless motor. By measuring the resistance of the output lead of the Hall element relative to the lead of the

When the temperature is 25 C, under the condition of standard test, the continuous mileage of the vehicle assembled by different forms of motor is different. We can refer to the data of the normal fat tire electric bike to

The inspection methods are as follows: Turn on the fat tire electric bike power and turn on the knob to make the motor rotate above 10 s at high speed without load. After the speed of the motor is stabilized,

First, using a non-contact infrared thermometer, or a multimeter temperature measuring baffle (a multimeter with temperature measurement, measuring the temperature of the end cover of the motor above 25 ¡æ above the ambient temperature), indicates that the temperature rise of

While undercooling and overheating are not good for fat tire electric bike, they are generally more likely to be cold (electric vehicles tend to get 30 cents less electric power in winter than in summer, but are more afraid of

The battery is first charged for general maintenance and then discharged at a 2-hour rate. During discharge, the voltage of the battery of fat tire electric bike is continuously measured, and the “backward” battery with insufficient discharge capacity is selected

Avoid travelling on rainy days. When driving on wet roads, you can only keep running if the depth of water is no more than the center of the electric wheel. Once the water on the road goes beyond the wheel

The imbalance of series battery of fat tire electric bike is a worldwide problem, and there are always “backward” batteries in the process of use. Its reason is various: have production reason, also have the reason of raw material, and

Reason 1: the inner bearing clearance of electric bicycle is large Treatment: replacement of bearings   Reason 2: motor rotor sweep Treatment: repair of stator, fat tire electric bike and rotor Reason 3: magnetic steel loosening Treatment method: rebonded magnetic

If the damage of integrated circuit is detected, it is necessary to replace the integrated circuit. Disassembly integrated circuit When disassembled, heat printed circuit board with flame of wine lamp to form circuit pin pad, move printed circuit board quickly

By measuring the supply voltage or signal voltage of the connecting parts or leads of the controller, we can analyze and determine the fault of the controller. Referring to the main phase check measurement diagram of the brushless controller, a

Recently, some data show that the sales data of electric bicycles in the United States ushered in explosive growth, with an increase of more than 400. Sales as high as 26.3 w, of which 80% of the sales from Chinese
