Tom:
Great issue.
One comment:
The article about regenerative breaking is incorrect when it says the
direction of motor rotation is reversed. It is not -- armature and
field excitations are changed such that it ceases being a motor and
becomes a generator.
Think about it, the torques involved in instantaneous reversal would be
enormous, uncomfortable for vehicle occupants, and even more so for the
shaft of the device, for it's very short life.

HI Jim…
Missed that when I read through it quickly, but thanks for the catch. I’ll see to it that the editor is made aware of that issue. Having worked in a lab for large motor and generators many, many years ago, I am well aware that shafts really do not to be twisted like that.
Thanks!

Now that I've had a chance to read it more closely, I'd really expect reversing the motor would simply break loose the drive wheels as they reversed direction and thus would leave serious skid marks and certainly bring you to a screeching halt.
Remember how you could burn rubber with a slightly under-torqued sedan by getting up some speed in reverse, the popping it into Drive with the throttle nearly floored?
And how your old man would be pissed when you had to tell him the tranny failed?

HI Jim…
Missed that when I read through it quickly, but thanks for the catch. I’ll see to it that the editor is made aware of that issue. Having worked in a lab for large motor and generators many, many years ago, I am well aware that shafts really do not to be twisted like that.
Thanks!

Great issue.
One comment:
The article about regenerative breaking is incorrect when it says the direction of motor rotation is reversed. It is not -- armature and field excitations are changed such that it ceases being a motor and becomes a generator.
Think about it, the torques involved in instantaneous reversal would be enormous, uncomfortable for vehicle occupants, and even more so for the shaft of the device, for it's very short life.

Now that I've had a chance to read it more closely, I'd really expect reversing the motor would simply break loose the drive wheels as they reversed direction and thus would leave serious skid marks and certainly bring you to a screeching halt.
Remember how you could burn rubber with a slightly under-torqued sedan by getting up some speed in reverse, the popping it into Drive with the throttle nearly floored?
And how your old man would be pissed when you had to tell him the tranny failed?

Tom:
Great issue.
One comment:
The article about regenerative breaking is incorrect when it says the
direction of motor rotation is reversed. It is not -- armature and field
excitations are changed such that it ceases being a motor and becomes a
generator.
Think about it, the torques involved in instantaneous reversal would be
enormous, uncomfortable for vehicle occupants, and even more so for the
shaft of the device, for it's very short life.

So it's correct - the article was titled Regenerative BREAKING, not
braking. ;-)
