Re: Info from Ah-ha! on BOSS's/Motors/HVdrivers

Hi,

It's a cost-benifit thing:

Benifit: Slight decrease in motor heating while stopped or turning
slowly. A very small improvement in high speed performance.

Cost: Time involved in disassembly, unsoldering center-tap, soldering
on 2 additional teflon insulation wires, insulating the junctions,
introducing them thru the existing wiring hole, reassembling the end
cap.

A single steel chip will render the motor useless. If there are any
about, the rotor magnet will find it and pull it into the air-gap. If
you pull the rotor out to remove it, it will instantly de-magnetize.
Add to that the good chance of damaging the winding insulation with a
screwdriver or soldering iron.
