SUMMARY

The discussion focuses on addressing the high starting torque issue in electric bicycles using Arduino. Key insights include the relationship between motor current and torque, emphasizing that insufficient starting torque may stem from limited motor current due to resistance. Suggestions include temporarily connecting two batteries in series to double the voltage and current for increased starting torque, and then reverting to parallel configuration for normal operation. Additionally, familiarization with H-bridge motor controllers is recommended for effective control of the motor.

PREREQUISITES
  • Understanding of DC motor torque and current relationships
  • Knowledge of battery configurations and their impact on voltage
  • Familiarity with Arduino programming for motor control
  • Basic concepts of H-bridge motor controllers
NEXT STEPS
  • Research Arduino libraries for motor control
  • Learn about H-bridge circuit design and implementation
  • Explore battery management systems for series and parallel configurations
  • Investigate torque calculations for DC motors
USEFUL FOR

Electronics enthusiasts, electric bicycle developers, and engineers looking to enhance motor performance and control in electric vehicles.

hi, i am doing an electric bicycle project. The basic improvement required would be the asist of the motor using arduino to solve for the high starting torque of the bicycle. And i don't know where should i start? Is there any comments?

The torque on the shaft of a DC motor is directly proportional to the current. It is probable that the lack of torque is due to the motor current being limited by the resistance of the motor. The battery voltage is probably appropriate for running speed, but not for starting.

A motor has a current rating and it's shaft is made strong enough to handle the resulting torque. If the starting current flowing is not the maximum rating then you might consider the following. If you could momentarily connect two batteries in series, you could get twice the voltage, so twice the starting current and twice the starting torque. Once moving, switch the batteries back into parallel.

It might be wise at this stage to familiarise yourself with switching motor controllers such as the H-bridge. http://en.wikipedia.org/wiki/H_bridge
 
I would imagine what the motor is ment to be then design it on paper
