I recently bought a 7x12 Homier and so far so good. The question I
have is when I shut the varible speed knob to off and manually turn
the lathe backwards I can feel a restriction. If I turn the
electric
switch to off it goes away. Its like the electronics are holding it
from being turned easily. The main question is will this hurt the
electronics? Its a pain to turn off the speed control and main
switch
just to turn it backwards a turn or so. When it is in reverse the
same thing happens. The restriction is felt only in one direction
not
the direction that forward reverse switch is set. Thank you for any
help Ken
Hi Ken:
Like most DC brush motor controllers you can reduce the speed control
to the point the motor stops turning. But this probably doesn't mean
that you can stop current through the motor by turning the speed
control to off. In this case the motor is still "on" but it just
isn't turning.
I think it would be normal to feel some residual effect and to truly
shut off the motor requires the main switch. Maybe the speed control
should say 0 rpm rather than "off".
my thoughts,
Mike...
