How much faster is a 1000W motor compared to an 800W motor?
4 Answers
1000W motor is one-fifth faster than 800W motor. Specific details are as follows: 1. Different power: Compared with 1000W motor, 800W motor has slower speed and provides less power. 2. Different power consumption: Under the same conditions, 800W motor consumes less power than 100W motor. 3. Different load capacity: 1000W motor can pull heavier goods and provide greater power. 4. Electric vehicle motor function: Generally, the carbon brushes of brushed motors should be replaced after about 2000 hours of wear. Ordinary hub motors and column motors (also called mid-mounted motors) require professional maintenance personnel to replace, while series motors can be replaced by ordinary users themselves. The wear of carbon brushes is also related to the current size and the silver content of the carbon brushes.
The difference between 1000 watts and 800 watts is simply calculated as 1000 divided by 800 equals 1.25, which means the power is 25% higher. However, it's hard to say exactly how much faster the motor speed will be because speed doesn't just depend on power, but also on many other factors like motor torque, load weight, voltage, etc. For example, if used in an electric vehicle, a 1000W motor can provide faster acceleration from a standstill compared to an 800W motor, such as reducing the 0 to 60 km/h acceleration time by maybe 5% to 10%. But this number is just an estimate, and the actual performance depends on the vehicle's battery configuration and overall design. In daily riding or driving, you might feel that the 1000W motor handles uphill climbs more easily and with less effort. However, higher power also means more energy consumption, potentially reducing the range a bit. So, for everyday use, an 800W motor is usually sufficient, and there's no need to chase after higher power.
I've been driving electric vehicles for several years and have tried motors with different power ratings. The 1000W motor is indeed faster than the 800W one, especially during acceleration and hill climbing—the difference is quite noticeable, with a more intense acceleration feeling, like effortlessly surging forward ten meters. However, on flat city roads, the difference isn't that significant, with a speed increase of just 5 to 10 km/h at most. It mainly depends on the battery condition and weight. For example, when carrying a passenger, an 800W motor might struggle, while a 1000W motor can still maintain steady acceleration. It's not a linear relationship—a 20% increase in power doesn't mean a 20% increase in speed. It might also consume more electricity, affecting range. So, when choosing a motor, consider actual needs rather than just chasing higher power.
A different perspective on efficiency: A 1000W motor has 25% more power than an 800W one, theoretically allowing for slight speed improvements, such as reduced acceleration time or a modest increase in top speed. However, the trade-off is higher power consumption, potentially using 10% to 15% more electricity, directly impacting range. For electric vehicles, this means more frequent charging, making long-distance travel less convenient. From an economic standpoint, the 800W motor offers better value, especially for city commuting—providing sufficient speed while saving power. Upgrading to 1000W isn’t necessary unless you frequently drive on highways or tackle steep hills.
