Hello.
Im new to this forum.
I have a intrest in EV cars and looking to do a budget build.

But firstly doesn anyone know of in in wheel hub electric motors?
I recent read a article about a university that converted a frwd car to awd and had two in hub motors in the rear tires. Supposedley only costing $3000. $3000 sounds very low for this type of build but i was intrested in the in wheel motors.

Anyone know where to start looking for one?

Or maybe even a motor that would connect to the drive shaft of a rwd.

Im intrested in keeping the engine in place and having some type of hybrid build.

Has anyone done this successfully?

Any belp would be appreciated.

Yes, you will have poor ride quality with hub motors this is one company moving forward with it that i know of

Dispite being one of the leaders in the field, even Protean dont appear to have "moved forward" with this concept in the last 4-5 years ?
I suspect one of the reasons is because the torque capability of these motors is a fraction of a conventional geared EV drive train (EG Tesla)
Their 1000Nm max is only similar (less infact) than Tesla cam produce at the motor,...before a 9.7:1 multiplication in the final drive gearing !
One other reason is of course the unmentioned cost of the (multiple) hub motors and the control systems required to drive them.
