Electric scooter motor fever? there are hidden dangers!
Electric scooter in the process of running will produce heat, but the temperature exceeds 40 degrees, and even more than 60 degrees, the motor enameled wire insulation may melt off, causing short circuit, the motor burned, dangerous.
Electric scooter motor fever for three reasons:
1.Motor internal failure
Part of the motor heating is due to the motor turns,the internal material of the coil is not the same as the motor power, heat will be different, the more thin lines, the greater the heat. We can replace the copper stator to reduce the motor temperature.
Bearing support rolling, steel ball gap as long as the increase, the stator friction rotor, will be laborious heat, friction increases, the temperature also increases. Can replace high-quality bearings to avoid problems.
The controller will generally heat, but overheating should pay attention. The controller adjusts the speed of the motor by means of the energy conversion current, which increases the motor temperature when the high current discharges. So it is recommended that the size of the controller and the motor to match.
3.Brake system failure
Brake spring off, rely on the external spring is difficult to brake pads in place, spring brake pads “closed” does not rebound, so that the brake brake has rolling resistance, resulting in motor temperature rise.
In addition, in the choice of battery brand, to choose excellent quality, good reputation of thebrand, such as Kingday electric scooter, Kingday quality, service, sales, service, customer service, technical support, maintenance and other aspects of construction is very perfect, Can give consumers a better after-sales service.
