Although efficiency is key these days there are more niches for the AC induction motor to fit in as you may think. Most of the induction machines are tied to the grid to run on a more or less precise and constant speed but by adding intelligent electronics you discover some interesting features of these machines. Additionally a FOC controlled induction machine can also reach very high efficiency.   These machines can have 3 main advantages: Intelligent control of this machine makes it pos ...

Who controls your drone?

Posted by simonj Jun 14, 2017
Born out of a combination of personal enthusiasm for drones and customer questions on low inductance or modular permanent magnet motors I did some test with some of these machines. For my own drone design I chose the AGM MT3510 which can easily consume 200 W.   To get started with drones I bought the ECS SimonK Afro but my intention was also to test how our InstaSpin algorithm is performing with this machine and maybe replace this ECS with my own designed hardware (like this: http://www. ...

Do you know your motor?

Posted by simonj Jun 9, 2017
InstaSpin promises to “Spin your motor in minutes” but how can I spin my three phase motor in minutes if I do not even know what its parameters are? So let’s start with identifying your machine. InstaSpin offers an automated identification process to find the motor parameter needed for the software encoder. The model behind this is pretty simple, it requires only the following parameters to work properly for synchronous machines: Resistance Rs Inductance Ls_d/q Flux linkage ...
I work for Texas Instruments since 2013 and throughout my career I was doing customer support for our motor control products so I wanted to share some of my experience and insights in the solution offerings of TI.   If you look at the TI motor control portfolio from a system perspective then you can separate them into two categories. There are very sophisticated solutions which target customers for servo drives or other industrial machines. Those solutions provide only the framework of the ...
