Unipolar/Bipolar Connections (2-Phase Motors) Unipolar and Bipolar Half Coil, because we’re using less turns, doesn’t give us great low speed torque, but because of the low inductance, holds the torque out to high speeds. Bipolar Series uses the full coil so it gives very good low speed torque but because of the high inductance, the torque drops off rapidly. Bipolar Parallel also uses the full coil so it gives good low speed performance and...
Testing the new IC from Toshiba, THB6064AH. Going well and will supply updates as I test further. stay tuned. For now I have attached the only instruction and datasheets I have for this chip. Looking to be rock solid and may be my choice for my upcoming DIY Homemade CNC. dP— Here’s some links to PDF’s on this IC: THB6064AH instructions Differences between THB6064H and...
There will be a pause in the update for the next month(s) as my shop moves home. With this move comes a complete renovation of a section of my home. I maybe posting about this as there are many solutions I have to complete that may help others out there. My first project is/was ripping out 3 old brink molded windows and replacing them. Of course they were special order and it took nearly a month to get these in from Home Depot. It was an interesting...
Got in an older DV9000 I felt like fixing. Dead as a door nail. No power. No Lights. Power cable held together by tape. So lets dig in and see what we find shall we??? Maybe this will help others as I am assuming this laptop has a series of problems. UPDATES TO FOLLOW—-> Tweet

The Kama Sutra of Digital Indigestion
Homo universalis; A man can do all things if he will.
Unipolar and Bipolar Half Coil, because we’re using less turns, doesn’t give us great low speed torque, but because of the low inductance, holds the torque out to high speeds.
Bipolar Series uses the full coil so it gives very good low speed torque but because of the high inductance, the torque drops off rapidly.
Bipolar Parallel also uses the full coil so it gives good low speed performance and its low inductance allows the torque to be held out to high speeds. But remember, we must increase current by 40% to get those advantages.

My first project is/was ripping out 3 old brink molded windows and replacing them. Of course they were special order and it took nearly a month to get these in from Home Depot. It was an interesting learning curve. There has been a lot of down pours the past week so I got 2 complete. 1 more to go.
I think I’ll post Pics and videos on the install and let others tear my work apart. Some others may find it informative

The Kama Sutra is the oldest and most notable of a group of texts known generically as Kama Shastra (Sanskrit: Kāma Śhāstra). Traditionally, the first transmission of Kama Shastra or “Discipline of Kama” is attributed to Nandi the sacred bull, Shiva‘s doorkeeper, who was moved to sacred utterance by overhearing the lovemaking of the god and his wife Parvati and later recorded his utterances for the benefit of mankind.
