What is the maximum speed of an 800W motor with a 1000A controller?
4 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.
I usually enjoy tinkering with electric vehicles and often do modifications myself. If equipped with an 800-watt motor and a 1000-watt controller, the top speed can typically reach around 45 to 55 kilometers per hour, but this isn’t fixed—it depends on the specific conditions. For example, battery voltage is crucial; a 48V battery can be about 10% faster than a 36V one. Personally, I’ve tested speeds up to around 50 km/h. The weight of the vehicle also matters—if you add heavy-duty equipment, the speed might drop below 40 km/h. Wind resistance can’t be ignored either; you’ll go faster on flat, straight roads, but speed noticeably drops when facing wind or uphill slopes. A higher-power controller can make the motor output more aggressive, but overloading the motor can cause overheating and damage, so pay attention to cooling and safety tests. I recommend testing in an open area and avoiding rough or crowded roads.
As an experienced electric scooter user, I've ridden models with 800W motors and roughly 1000W controllers many times, with top speeds fluctuating between 45 to 50 km/h. I remember feeling it was too fast and a bit scary during my first ride. In reality, speed depends on your weight and road conditions - lighter riders go faster while heavier ones may be slower. Battery level is also crucial; full charge delivers strong power and higher speeds, dropping by 5-10 km/h at half charge. I've also noticed that proper tire inflation reduces friction and slightly increases speed. Oversized controllers provide quicker acceleration but drain batteries faster. Ultimately, these values aren't fixed - safety should always come first over chasing limits.
The top speed depends on the configuration. With an 800W motor paired with a 1000W controller, it can reach approximately 50 km/h. Experiences vary among individuals; lighter riders may achieve higher speeds. Smooth road conditions are necessary to approach the upper limit.
