Elaboración de un dispositivo capaz de bloquear la señal Bluetooth 2.4g con un alcance aproximado de 20 metros

I want to build a BLDC Motor driver for 310V Motors which means a 230VAC Input. Basically it can be based on existing development kits (Infineon/STM/etc.). Example like this from STM: Please lets discuss which MCU and Software could be used to program different motor types.

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.

We developed custom brushless motors with generators for our octocopter drone. We need someone to order the parts, assemble them, build prototypes. If the motors need to be redesigned after testing, we need to assist in the redesign. The motors are one motor on the top and another one on the bottom. Our own motors integrate the top and bottom motors in order to reduce space. We want the ESC to be integrated into the motors. We want own foldable 30-inch carbon fiber propellers (3 Blades) with a snap-on locking system for easy removal. Our goal is one hour flight time with 30lb payload.
