Question

if the wheel diameter, gear ratio and speed of vehicle are halved. what will be it's effect on rpm of electric motor

​

Answer 1

If the size of the wheel is big which means it takes much more time to complete one round.

• So, therefore it effect the rpm of electric motor, as the size increases the rpm will take much more time.
• Speed of motor depends upon the torque, as it acts as the resistance.
• Therefore they are inversely proportional to each other, as they torque increases the speed decreases.
• The gear ratio, it decreases the power consumption of the motor given a vertical distance travel by the gear ratio.
