As an engineer, I need to specify the components and characteristics of the electric motor for an electric bike to ensure it meets the performance, safety, and efficiency standards required for consumer use.
Acceptance Criteria
[ ] The motor must have a nominal power output of 250 watts to comply with regulations.
[ ] It should operate efficiently at a voltage range of 36 to 48 volts.
[ ] The motor must have a peak torque output of at least 40 Nm to ensure adequate hill-climbing ability.
[ ] It should be rated for a minimum IP Rating of IP65 to withstand dust and water exposure.
[ ] The motor's weight should not exceed 3 kilograms to maintain the overall bike's lightweight structure.
[ ] It must be compatible with the bike's control system, supporting both pedal-assist and throttle modes.
[ ] There should be overheat protection to prevent damage under high-usage scenarios.
[ ] The lifecycle of the motor should be at least 10,000 hours of operation to ensure durability.
