How fast can a 350W motor actually run?
2 Answers
350W motor has a maximum speed of 30KM/H. This data is obtained under good vehicle condition, flat road surface, and no overload. The actual mileage is related to various factors such as vehicle condition, road condition, and load. Moreover, as the battery capacity decreases with use, the mileage will gradually shorten. Here are some maintenance tips for the motor: 1. Usage environment: The usage environment should always be kept dry, the motor surface should be kept clean, and the air inlet should not be blocked by dust, fibers, etc. 2. Thermal protection activation: When the motor's thermal protection is continuously activated, it should be determined whether the fault comes from the motor, overload, or the protection device setting value is too low. After eliminating the fault, it can be put into operation. 3. Ensure good lubrication of the motor: Generally, after the motor runs for about 5000 hours, the grease should be replenished or replaced. If the bearing overheats or the grease deteriorates during operation, the grease should be replaced in time. When replacing the grease, the old lubricating oil should be removed, and the bearing and bearing cover oil groove should be cleaned with gasoline. 4. Timely bearing replacement: When the bearing life ends, the vibration and noise of the motor operation will increase significantly. When the radial clearance of the bearing reaches the following value, the bearing should be replaced. 5. Motor disassembly: When disassembling the motor, the rotor can be taken out from the shaft extension end or the non-extension end. If it is not necessary to remove the fan, it is more convenient to take out the rotor from the non-shaft extension end. When pulling the rotor out of the stator, care should be taken to prevent damage to the stator winding or insulation.
As someone very familiar with electric vehicles, I find the speed of a 350W motor quite interesting. It typically achieves 25 to 35 kilometers per hour in real-world tests, depending on the vehicle's weight and road conditions. For example, if you're riding a lightweight e-bike on flat terrain, you can easily reach 30 km/h, but once you add a backpack or tackle a small hill, the speed might drop below 15 km/h. Key factors include motor efficiency, battery voltage, and wind resistance—higher voltage means greater torque and faster speed. However, don't expect it to race like a car, as its advantages lie in low power consumption and energy efficiency. For daily use, I recommend checking tire pressure and battery health to ensure more stable and reliable test results.
