Description:MOTOR: Brushless direct current motor is a type of synchronous motor, where magnetic fields
generated by both stator and rotor have the same frequency. The BLDC motor has a longer life
because no brushes are needed. It has high starting torque, high no-load speed, and small energy
loss.
The structure of a BLDC motor is classified into two parts:
• rotor.
• stator.
CONTROLLER: The electric bike speed controller sends signals to the bike. It is an electronic
circuit that not only controls the speed of an electric motor but also serves as a dynamic brake.
This controller unit uses power from the battery box and drives it to the motor. Different types
of controllers are used for brushed and brushless motors. for adaptive e-bikes, a conversion kit
is used, and a controller is the core component of that kit.
BATTERY: Lithium-ion rechargeable battery of 24V, 10 amp is used. It basically stores the
electrical energy generated and utilizes it to run the motor. A battery has a positive terminal
called the cathode and a negative terminal called the anode. The terminal marked positive is at
higher electric potential energy and the terminal marked negative is the source of electrons
when connected to an external circuit electron will flow and deliver energy to external devices
rechargeable batteries can be recharged multiple times.
The components of an e-bike kit include an electric motor, a battery, a controller, a throttle, a
friction driver, and various cables and wiring the motor, battery, and controller are placed inside
the kit and the friction driver is placed on the tyre of the bicycle as shown in the Figure The
motor provides the extra power which needs to get around, while the controller and throttle
allows to adjust the speed and power output. The friction driver is powered by the motor with
the help of a chain connected to a gear on both ends. The movement of the tire happens due to
the friction between the driver and the tire. Energy is developed by the battery to power up the
motor and the cables and wiring connect the components for efficient use. , C , Claims:Claim 1: A method for converting a normal bicycle into an electric vehicle comprising the
