We want to develop a high-efficiency motor controller for an aerospace application (Remotely Piloted Aircraft Systems). Weight is therefore a critical consideration in the motor controller design. Once we have established an optimal design / software configuration using a TI DRV8301 and TI InstaSPIN MOTION, is there a core components list that outlines the critical components required to develop the final motor controller that we could use as the basis for determining the final controller weight.
For example, we know that we will require a Piccolo F2806x for control of up to two motors and then there are the FETs. How many do we require per controller and what TI part numbers are we looking at for say an 11V, 10A controller, what part number for a TI motor pre-driver and voltage regulator? What other critical components do we require? The ideal would be to develop a spreadsheet where we would have a list of TI components, with their weights and depending upon voltage and max current draw could quickly establish the motor controller parts list, including number of components of the same type and the approx mass of the motor controller by total components selected. Any advice on this would be gratefully received.
