ting the project, our team extensively researched and
acquired fundamental knowledge in the following areas:


Learn about BLDC motor (structure, principle, control method,...)



Learn how to control BLDC motor without using Hall sensor.



Learn about transmission ratios and shaft design to be able to transmit gears properly and
at the desired speed to replace starter motor on motorbike based on Attila Elizabeth Fi
vehicle parameters.
The study provides a model to replace brushless motors with an overview of operating

parameters and conditions. BLDC motors have higher power density, higher efficiency and
higher speed range
6.2. Topic development directions

51

Although we have completed the project on schedule, due to objective factors, the model
certainly still needs to be supplemented and perfected, demonstrating many functions of the
BLDC motor so that it can be relied upon. Widely applied on motorbikes. Next, the
implementation team would like to suggest some future development directions for the topic:


The iron frame design is such that it can be mounted without having to remove the saddle
and air filter.



Control a 3-phase BLDC motor, we need a brushless motor controller. Currently, the
BLDC motor is controlled by a 24V battery to have enough motor capacity to operate
under the given conditions. In the future, we hope to be able to control the motor with
12V voltage, along with the electrical system on the motorbike.
