Electric Bicycle Controller Design

36v 48v 350w brushless motor controller kkmoon electric bicycle e bike scooter speed controller dc brushless motor regulator speed controller.

Electric bicycle controller design. An electric bicycle has a conventional bicycle frame pedals cranks chain and freewheel assembly. Robust protection features such as overcurrent shutdown and pre driver faults are included in these simple and compact solutions. The electric bike controller is one of the main parts of an electric bike it is the brain of the e bike controlling the motor s speed start stop. It was tested around about 10 mile every day and this controller is tested and trouble free.

It is connected to all the other electronic parts such as the battery motor and the throttle if exist. This e bike use very small amount of amps like 10 amps at 50 volts. All decent electric vehicles need a motor controller of some kind. It is connected to all the other electronic parts such as the battery motor and the throttle accelerator display speedometer pas or other speed sensors if exist.

The controller that we are making is designed for this e bike. I designed this controller for my crystalite sparrow 48v electric bicycle hub motor. Today s e bike systems often require. Controller circuit design 3 1 main control chip electric bicycle features high performance pic16f72 microcontroller core.

We are using irfp4468 field effect power transistor are rate 195 amps at 100 volts maximum. Hardware requirements for design of an electric bicycle control are postulated and basic blocks along with their usage are shown. 3 9 out of 5 stars 30. It takes all the inputs from all the other components and determine what should be signaled to them in return.

Get it as soon as tue oct 27. Pic16f72 has 28 pins include 22 8 bit i o ports. On a bike with a very small motor it might be possible to just have an on off arrangement and i suppose there are other less expensive and much cruder ways to control speed but i feel that a decent controller is absolutely necessary with a powerful motor like this. Ccp1 pin can output the maximum resolution of 10bit adjustable pwm signal.

The electric bicycle controller. Electric propulsion replaces or supplements muscle power. The pic16f72 supports pwm for motor control. 6 coupon applied at checkout save 6 with coupon.

Our integrated circuits and reference designs help you create compact robust and precise motor control systems for an e bike at a reduced system cost. It does this with a technique called pulse width modulation or pwm more on this later.
