What is the maximum speed of an 800W motor with a 1000A controller?
1 Answers
Electric vehicles with 800W motors generally have a speed range of 35km/h to 40km/h, which is a speed limit set by manufacturers to ensure battery life. Typically, 60V electric vehicles are limited to speeds below 35km/h, while 72V electric vehicles are limited to speeds below 40km/h. By removing the voltage limit of the controller and increasing the current, the motor's speed can be increased. After removing the speed limit, the maximum speed can reach around 50km/h. Additional content, precautions: 1. Charging: Avoid charging for too long. In summer, high temperatures increase the risk of battery thermal runaway. It is best to charge for 6-8 hours. If the battery is not used for a long time, it is recommended to recharge it every two months to prevent irreversible sulfation due to prolonged discharge, which can kill the battery. After six months to a year of use, it is advisable to add supplementary fluid to the battery to extend its lifespan. 2. Pay attention to riding with or without brakes: Riding with brakes engaged causes the motor to heat up, leading to demagnetization of the magnets, resulting in reduced power and shorter battery life. If the motor makes noise, repair it promptly and check the bearings to prevent steel particles from rolling out and cutting the coils, which can render the motor useless.
