hi guys

i am a keen motorcycle enthusiast and have noticed the direction of vehicles is begining to sway towards electric rather than fossil fuel

i have done quite a bit of research and looked at many youtube videos but alas find my self still struggling


what i would like to do is build my own 3 phase brushless DC motor complete with hall sensors and speed control

but i am currently strugling to figure out the best way of doing this as i would like a fully adaptable controller to run of off a \"throttle like\" accelerator, when i buy a motor/speed control i dont mind paying a premium if it is fully customisable to multiple application, or if somebody could direct me to a place that teaches how to build a basic one so i can learn from there


i was hoping to build the motor myself too using aluminium windings but am stuggling to find suitable cores and permanant magnets

i know that i have asked alot of questions but if you could help me get started, i want to start small but i would like to learnand i find doing it is the best way

thanks alot guys

We do offer a wide variety of Motor controllers. The brushless 3 phase (UVW) can be found here on our website link, each with their respective datasheet.

dev.roboteq.com/dev1/brushless-dc-motor-...controllers-selector

The BL1500 is an Obsolete product; we strongly recommended that you would use one of our new generation brushless controller.

What are the power requirements of the motor, and how many units are you looking to build.

Each of our controllers settings can be configured to work with your application.

For a throttle use, you will need one that has the built in pot (Recommended 5K), and this will be used on your analog input). The datasheet will provide you the wiring pin outs.

If you need more additional information for quicker responses, you can email us here at this address.

hi there,
well i am planning on making my motor with 1mm enammaled aluminium wire using 6 cores with 20 windings on each core using a 125mm diameter permanant magnet that is removed from a motorcycle generator, i am planning on powering it using 3 9v batteries to total 27v, im not sure what the output will be i was planning on trying to measure this as it will be my very first attempt at anything like this and i am a complete novice.
at the moment it is just a home project, a bit of a hobbie as such i would like to do my first motor on a very tight budget,
but i would like to work my way up to building/buying a motor capable of powering a motorcycle, looking at other electric vehicles this would be around 350v and 250 amperes

as such i i was planning on familiarising myself with a good control early on as well as save myself some money due to the price of the products or do you think that it might be worth my while to start with a cheap control to practice with

any other advice on my set up, how to do it or suggestions would be greatly appriciated

thanks very much

Making your own motor is a big job and probably not worth it given the wide choice of what is available.

It is a lot harder to make than it seems.

Look at the various hub motors from golden motors, for example.

Since we do not specialize in motors, we are unable to help you on your motor build. I\'d suggest you try some more searching to see if more information is available on the web for that.

In terms of motor controller of such high capacity, we do not currently have a motor that can drive 350V @ 250A.

The smallest/cheapest end of BL controllers we have is our SBL1330, SBL1360.

dev.roboteq.com/dev1/brushless-dc-motor-...l-and-encoder-inputs

This is rated 30V or 60V.

If you are looking to see what kind of interface we offer, I suggest you download our Roborun+ software and install.

In the interface in the top right, there is a work offline checkbox you can select, and then under it a drop down box of our controllers. Select the one you wish to look at, and you can see what is available in terms of functionality and controls.
