Hoverboard Motor Specs?
Steffan Carroll
matter, can anyone explain what these specs mean? e.g., isn't the stall
torque the same as the max torque? I mean, if you've got a torque load of
430 oz-in, then the motor has not stalled, so it's producing 430 oz-in of
torque, right?
Or is it that anything over the max torque of 225 oz-in will cause the motor
to overheat and fail, and the speed of failure increases from 225 oz-in up
to 440 oz-in at which point failure is immediate?
MOTOR:
Z: 12 V ceramic, permanent magnet DC motor, .5 hp at 3,500 RPM peak.
Continuous 150 Watts @ 3000 RPMs (Output at motor spindle), MTBF: ???,
Cost: ???
H: 24V DC, Continuous: 150 Watts @ ??? MTBF: ???, Cost: ???
TORQUE
Z: Continuous: 75 oz-in @ 3000 RPMs, Max: 225 oz-in @ 1750 RPMs, Stall: 440
oz-in
H: ????

would assume that the MAX torque would be the torque produced at max RPM.
BTW - Have you tried calling PMW about this? You seem to have a hell of a
lot of question that they coud answer rather easily.

email address for asking such questions. Whoever made the decision to go
with a particular motor makes that decision and then often the information
is lost or forgotten, in anycase, the person who answers the phone probably
doesn't know, and I'm not about to buy a Hoverboard, so it's not a pre-sale
question.
But if there is someone from PMW that has the time to read these messages
then maybe they've got the time to answer my questions.
I'd like to know who the motor supplier is, They'd know these things. I
haven't taken the Zappy apart enough to determine if the manufacturers name
is on their motor someplace.

manufactures the motor. Is that relevant to performance?
Do you have a life?
Is that rude for me to ask?

Just like motorized goped owners like to modify their engine, if you've got
detailed specs on the motor then you can possibly change it to your liking.
And I've got a couple of traffic tickets that I'm defending for which some
of this information may be very useful.

Actually, I do have a problem in that area. I've got a mild internet
addiction. My kids have definitely diagnosed the problem. Also I get swept
up in "causes" and for the last week or so, this has been mine. In another
few weeks, you'll probably never hear from me again. I know many on this
list will be glad to see that happen.

No. Not in this manner. Thanks for caring.

its a calculated guess on how long the device in questions will live.

complex calculations based on a statistical analysis of all the components
and subsequent testing. Motors are designed with a specific target MTBF. A
1000 hour motor is going to be much less expensive than a 10,000 hour motor.
The Zappy has NO motor maintenance schedule. It runs until it stops. But
how long is that suppose to be?
