How fast can a maximum power of 80 run?
3 Answers
Maximum power of 80 can run 53 meters per second, approximately 190 kilometers per hour. The relevant introduction to maximum speed is as follows: Factors affecting speed: The higher the voltage, the faster the speed. The larger the current limit of the controller, the faster the speed. Secondly, for the motor itself, the more magnetic steel inside, the faster the speed. Lithium iron phosphate batteries are better than lead-acid batteries. With the same motor, lithium iron phosphate batteries provide faster speed. Finally, it also involves the tires. Working principle of the motor: The direction of the force on the conductor is determined by the left-hand rule. This pair of electromagnetic forces forms a torque acting on the armature, which is called electromagnetic torque in a rotating motor. The direction of the torque is counterclockwise, attempting to make the armature rotate counterclockwise. If this electromagnetic torque can overcome the resistance torque on the armature, the armature can rotate counterclockwise.
I've driven quite a few 80kW cars, and the actual speed isn't that straightforward. While power is crucial, factors like vehicle weight and aerodynamic drag have significant impacts. For example, the compact car I drove before was relatively lightweight, paired with good tires and low-drag design, could maintain around 140km/h on highways. However, when fully loaded or on slopes, it might drop to 120. I've also tried manual transmission techniques – on flat roads with a short sprint, it could briefly reach 150, but this consumes more fuel and strains the engine. True high-speed performance depends on overall matching, like properly calibrated gear ratios, otherwise the power can't be fully utilized. Safe driving is paramount – I recommend not pushing too hard, especially since urban roads typically have 120km/h speed limits, which is sufficient.
I remember driving an 80kW hatchback a few years ago. It accelerated quite fast for city commuting and could easily reach 130km/h on the highway. But one windy day, the car felt a bit floaty, so I had to keep it around 110. Vehicle condition is also crucial—the technician during maintenance said tire wear or transmission slippage could affect speed. Nowadays, I focus more on practicality; cruising at 120-130km/h on the highway is the norm, and exceeding 140 increases wind noise and fuel consumption. A friend with the same power output modified the intake and exhaust, claiming it could hit 160, but that's dangerous and could attract police attention. Don't chase extremes; safe and steady driving is what matters most.
