NickG - cheers for the links. I know the original Toylanders are 12v motors but quite a few are buying these 24v motors but then you need two batteries if using regular car ones. I`ll still have to have a think about it.

Trust me... I CAN never forget that my daughter has boundless energy. bike, scooter, three balls, a skipping rope and some wierd shoes with wheels on the bottom of them....and that is just what I can see sat here in my living room typing this message.

Hi Chris

FWIW I think the battery powered idea is the one to go with. I bought my kids one, a 4 wheel off road look alike similar to a Honda off road bike, and it was a hit from day one, managed to take both of them on it and a friend all at the same time, they eventually (3 yrs) wore it out. The reason I advocate going for a battery drive is the weight of the vehicle and the ability to stop it. With the one I bought when it was not in drive the motor leads were short circuited leading to dynamic braking. The kids would also switch it into reverse whilst going flat out forward so I guess it must have been tough.

Good luck with your project, I'm sure your young assistant will love it.

Best Regards

Do you have power wheels over there? 6 or 12 volt systems, all in a ready made package. Small motors (about 1.5" diameter by 4" long), but plenty powerful enough to push a kid around.

push a kid around .... I want it to push me around as well :lol: :drool:

Chris, an idea for the motor and controls...

Some washing machines are driven by huge stepper motors, one or two horsepower at full power. Of course they produce torque at low revs (even stall).

Now, the germ of the idea!

This is a sweet you lady young have in that machine and you want controls to be easy, safe and easy to learn.

SO...... make a set of regular pedals (rotary kind) and fit a multi position switch to the pedals and wire that switch to the stepper motor coils. As she turns the pedals the appropriate coils in the motor will energise, faster, slower, backwards, forwards, all as per natural pedalling but with the horsepower of the motor to drive the Toyrover. Stopping pedalling puts the brake on too.

The motor coils in the NZ made (now also made in other countries) Fisher and Paykel washing machine are full power at about 40 volts (and can spin 10kgs of wet socks to 1000rpm in seconds) but I expect 12 volts would be about right for that machine. Other marques make motors like that and some use the F&P motors.

This is what the motor looks like:-

The bit with the shaft is just the bearing holder, the stator is the bit with the coils and the rotor is the gray plastic bit which carried permanent magnets and fits around the outside of the stator.
