In Search of DC Hub Motors

try here lynch motors

I agree with Del. Lynch motors driving the wheels via the normal drive shafts is the second simplest option on a HUM VEE. The best option is to place a twenty HP lynch motor on the PTO from the transfer case and remove first gear (if it isn't needed for reverse as it is in a early landrover) That way you can select electric drive in the city when you are stopped at the lights, when you need more speed a change to second should start the engine and the extra torque is provided by the electric motor. You can still charge the batteries at standstill by selecting neutral in the transfer case or using an extra big alternator best option. Third method of course is to belt drive the electric motor from the harmonic balancer same as the alternator, in the same ilk as a supercharger is driven. A turbo alternator from the exhaust is a fourth option for the home handyman

Big power hub motors weigh a lot and it is all unsprung which will cause all sorts of dangerous engineering problems to your vehicle, like the wheels falling off.

30W -- 200W hub motor refer to

I can also offer you chiese character web site if you can read.

cater to 12v--48v

ARGH, in wheel motors, all I see is a major problem called "un-sprung weight"

Those motors would go ok in a ideal world, but are you going to upgrade your suspension components to cater for the added weight?

The thing is, with the wheel on the road, the suspension is supporting the weight of the car, when your moving, the springs/shockers are supporting the car and help it give comfort to the occupants, you hit a pot-hole and you feel a dampened nudge in the car.

*BUT*

Hitting the same pothole (speedbump, driveway verge, stick, rock, debris) your wheel shoots upwards (pothole down then up, lump, up 1st) then the shockers are coming into action to suppress the huge inertia of the rising wheel, converting it into heat, with greater mass on your wheels, the shockers must try and decel a greater force acting against it, if you plan to put a motor in the wheel, your shocker systems and suspension components must be able to tolerate this added mass.

Placing those drive components into the chassis inboard, the suspension components don't have to deal with that unsprung mass, just the wheel.

Very well put!

did you notice how far the wheels on the PMl mini stick out from the guard? making it unregisterable in most countries!

You should also notice that a normal wheel is like about 10KG those motors start around 45kg so even half that weight gives an all up weight of 32.5 kg; over three times the design weight, all unsprung

what is the qty u have in Mind?pl specify DC Voltage and power rating .Probably I can revert after getting these details.
