At about the time of 10/2/2008 1:20 AM, Graz stated the following:
The only electronics (on a face plate) attached to the motor are a ST
electronics BTB16 600BW chip (used for phase control in motor speed
controllers) and an unidentified cylindrical component marked only as
"43-02 97C".

Just curious whether the failure of either of these could be causing
the motor failure symptoms in the subject line,

That 43-02 sounds like a motor running capacitor...43uf maybe? The 97C
means that it will function correctly up to 97 degrees Celsius. A
failure of the cap will cause problems.

OK, thanks. I will try to measure the ESR on it. What sort of
problems could failure cause?

The chip mentioned is not a IC
per say, but it's a triac.
http://www.datasheetcatalog.org/data...onics/7471.pdf is
the datasheet on it.

It sounds like the motor is a standard induction motor with a 90 degree
phase controlled startup winding.

Apparently it's also brushless. And not amenable to dissasembly.
