Electric scooters are powered by the motor, this is normally, but not always located in the front wheel making the electric scooter front wheel drive. The motor together with the battery determines how your scooter performs - how fast it will go, how well it climbs hills and how the power from the battery is consumed. The battery and the motor need to be matched, there is no point having the largest battery if the motor is so low powered you are overtaken by a snail!
Electric scooter motors use a brushless technology, this is a newer type of motor that doesn’t use physical contacts or brushes to power the motor. There are a number of advantages to a brushless motor over the brushed type:-
● no bushes to wear out due to friction
● more efficient
● longer lifespan
Electric motors are rated in Watts and, as we all remember from school the formula to calculate the power consumed is:-
Power (Watts) = Volts (V) x Amps (A)
A higher Watt value equates to an e-scooter that will accelerate quicker, carry a heavier load and will be able to climb steeper hills.
When browsing scooter specifications you will come across, peak power as well as sustained / continuous power.
Peak power refers to the maximum amount of power the motor can consume for a short period of time. However the “short period of time” various among manufactures making if difficult to compare - so it’s best to ignore this rating.
Sustained (or continuous power) is the maximum amount of power the motor can consume indefinitely. This is the most useful measure for comparing motor performance among electric scooters.
When comparing motors torque also needs to be taken into account, measured in Newton Meters (NM), torque is the twisting force produced by the motor. Torque is the force that rotates your electric scooter’s wheel and propels you forward. Torque ratings however aren’t normally listed on specification tables.
