Got a new motor and now have a controller. Have a major problem with joining the motor shaft to the gearbox.

The motor shaft is 23mm and 28 spline. Can anybody recommend a coupler to join them?

A few pics,

4kW ... not much better.

Take this motor to workshop, someone will produce proper coupling.

A few pics,
I'd still say it's a little small, It'll move the car but not too well, think of it a the same amount of power as a moped engine.

what is the diameter?

Is it a pump motor?

If you could get hold of whatever it used to drive or something to match the splines then you have something to work from.

Creating a splines coupler from scratch could be very expensive...

Are you using a clutch or not?

Cheers,

Mike

Hi, Im from county Waterford and my son and I are considering an ev conversion. We are still at the stage of collecting parts, motors etc. We are looking at VW polos because they did not have power steering up to about 1998 and this would take some of the load off the dc/dc converter. Does your donor car have power steering?
Have you looked into the matter of registration of a home built ev?

Hi Dit

Motor looks interesting - how big is it? - what do the brushes look like?

I would suggest having a look at local industrial suppliers - I bet that is a standard spline and you will be able to buy the female

Where did you get it? If it is off a local dead forklift have a look at the rest of the bits - there may be a part that you can turn into an adapter

That's the same motor as I'm using on the bike. Two of them actually.

I had a local machine shop turn the splines off the shaft , down to 19mm and keyed 6mm. Those motors have a high bar count so with some advance will run at higher voltages. 48v on the two nearly put me through the back wall of my workshop!

Got a taper coupling to join the motor to the gearbox, not using a clutch so hopefully the coupler will hold.

Sweet work!

How are you planning on mounting the motor to the chassis?

What are your plans for controller, batteries and charger?

More pictures needed ;-)

Cheers,

Mike

Hi Mike,

We have secured the motor to the mounting plate and have webbed welded supports on the back so hopefully it will hold it.

The controller is still unknown at the moment but will hopefully be sorted in the next week or two. Batteries are just going to be normal run of the mil car batteries as the budget is pretty tight and the car is not going to be going any kind of distance.

Check out our website for loads more pics.
