I'm not really sure what people who say this are thinking... considering that forklift motors are solid mounted, and take some really hard hits due to people not really caring about the health of the forklift... especially when they push the accelerator into reverse while still driving at nearly full speed forward... you dont think the instant, high power change in polarity causes a few variances in "normal" operation?

This also tails onto the fact that all these guys with EV's are vibrating the hell out of them.. and every time they hit a bump, the weight of the motor/transmission combo is forced to move inside the boundaries of the mounts they are attached to, many of which are solid at least at one point. You think this doesn't equate to "taking a hit"?

Granted, the hit will temporarily break down the magnetic field of the motor, and might cause some runout on the bearings due to the weight of the armature... but nothing more than what happens every day anyway.

The real bane of MIW (Motor in Wheel) designs is the cost effectiveness... there aren't too many motor designs that make it cost effective to have one in each wheel, not to mention the practicality. The company that provides those kits had to make a bunch of excuses as to why it was good to have. One of those excuses was 160HP PER WHEEL.

It's not practical or cost effective, honestly.. what it really is, is cool.

But as far as saying that the motor can't withstand "road impacts", I believe you're surely mistaken here.
