Infineon controller

[fishingpaul]

Anybody had any experience with an infineon controller,i am looking at the 36v/48v 30a controller.

Interesting you should mention this as I recently contacted Infineon directly to find out more about their e bike controllers. They told me they don't make e bike controllers. Infineon just supply the MCU (Micro Control Unit I think) which other companies then use in their products. So basically it's a bit misleading of anyone to sell you an Infineon controller as if it is manufcatured by them as it's not, they just use some parts and likely have product support to help design the required circuit to support and use the MCU.

So basically you just need to judge the individual supplier/manufacturer. I believe Ecrazyman uses them in his products but I haven't had the opportunity to test any yet but hope to in the near future.

Although having said all of that, Infineon controllers do seem to have a good reputation and a 30A, 48V is a pretty serious bit of kit that would very easily drive your overvoltaged motor and likely much significantly more powerful motors too, so it will probably not even get warm. Just need to be careful that you don't pull too much current out of the battery and make that the next weekest link in the chain/system. You may be able to get the option of a variable power switch/selector that is basically some preset, selectable current limits that could be used as appropriate to both keep you legal on the road and then up the power when you hit that private road

Be very interested to hear your thoughts if you do decide to get 1. Where from and also what sort of retail price they go for.

Infineon is a semiconductor company. They don't make any finished products, just chips. They used to be part of Siemens.

The term "Infineon controller" gets used loosely. It tends to just mean a certain style of controller with programmable features. I think some of them even have other company's microcontrollers inside.

Some semiconductor manufacturers make dedicated ICs for brushless motor control, but AFAIK the "Infineon" controllers use general purpose microcontrollers.
