Microchip PIC16 Microcontroller PCB & Driver design

Design a BLDC motor driver for a 24 volt 2 Amp 3 phase 'outside running' motor (external rotor motor).

Motor specs:

12 pole stator, 16 pole magnet ring, 8,000 R.P.M.

3 phase winding A-B-C-A-B-C-A-B-C-A-B-C all windings same direction.

Power input 24 volt Max. 1.9 Amp.

To do:

Design Hardware & Software for BLDC Sensor less Controller, complete with:

- Hardware circuit Design

- Software design

- PCB Design

- B.O.M. List

The motor will only be switched 'on and off' by a simple on/off switch.

No speed control needed.

PCB Board dimensions: width 60 mm. x 60 mm. (or longer if necessary)

Looking for a low cost micro-controller, so will look at BOM offered by the designer. Overall PCB should cost less than $5.00 assembled in bulk.

Working and original Source code with commented explanation of process must be turned over to the prior to payment.

We use Altium designer and Prefer to use a micro-controller from microchip (dot) com. Working simulation required prior to final design being sent to the factory for prototype assembly. While waiting (1 week) for the assemble to be completed, you should finalize the code and compile to HEX for testing. Testing will include speed control at 8000RPM constant and economical use of power. This motor is similar to a model airplane motor or a BLDC fan motor. Operates only on or off. On is 8000RPM with a start-up sequence to drive motor to correct and maintained speed. ABC sensor design should be embedded with PCB design through monitoring ABC signals.

First milestone (50%) will be based on a working PCB after assembly and working HEX file drives motor to 8000RPM. No pre-payment offered what so ever. Final payment to be made after you turnover the source code and testing is completed. We use team viewer to allow you to work together with us. We expect the project to take 7 days to design, 10 days to assemble prototype and then 5 days to test. If you can work in that or better time frame please advise in your bid.

We have an Altium design that was made prior to offering this job. The programmer did not have enough experience or knowledge to complete the job. We can share this information with you to redesign and use as a point of reference. We believe the design is flawed in the sensor voltage feedback signal being too low for the PIC18 micro controller.

Please only bid if you think this is an easy project and have experience in designing PCB's and writing code for the driver. Feel free to ask any questions you wish. Thank you for reviewing my project!

Actually PIC16 will most likely not work for this project as it shows in the name. PIC18 such as PIC18F13K22 or other would work better. I am attaching a design for reference that needs work, Sensor design is flawed, but gives an idea of the work needed.

the attached file called 'PCB board design drawing" is showing the Dimensional and size layout of the PCB. please review
