Need an electrical enginner of extensive electronic knowledge to develop an inexpensive motor controller for a synchronous reluctance motor. Project premisses are: - project must be of a production level of detail, so that it can be mass manufactured with third party facilities (gerber files, CAD files and everything related to fabrication must be developed); - the design must be of very low complexity to produce and low cost, all of that within a robust package; - minimum efficiency of 95% when on maximum power output (about 200kW); - BOM list of about 250$ maximum; - clever selection and sourcing for components in order to avoid shortages that would harm mass production.

A simple pcb bord it's an hour work if intrested only can bid preferably new freelancers

The device is an ion exchanger. It is therefore used to extract ions from media, in this case water. This can be ensured, as long as the device has “space” for the ions. This unit is reprocessed with acids and alkalis after it arrives at the factory. This process lasts from several days to several months, so all materials worked with should be fully resistant to the corrosive and abrasive effects of said media. The device already exists and is now to be extended with useful features for the plant and customers. These various sub-items are assigned as one package, various packages, or separately, depending on competency. The developments of the sensor technology, as well as the processing of the electrical signals resulting from primary goal is the development of customize...

I like to design 5KW inverter and I need support in areas of DC to AC inverter design PCB design

I need to design a pcb layout 2 layer with ALTIUM Designer v.20. All components are in bottom layer, except push-buttons, USB connector and OLED. These components are locked on top layer and they must not be moved. I drew a probable size of the circuit (67x15mm), anyway it can be resized by few millimeters. For payment, I would create two milestones with release of first milestone after the placement of all components (without tracks).
