In addition, the Company has granted the underwriters a day option to purchase up toadditional shares of common stock at the initial public offering price, less the underwriting discount. All of the shares sold in the offering were offered by the Company. Jefferies and Cowen acted as joint book-running managers for the offering.
Hi Evilsanta Like pete sayd the poles depends of speed and frequency. IMO you want to know how connect a winding to get a determinate pole number.
This depends of experience and is a hard issue, so could be good that you play attention to your collegue and read some basic books or guides about winding motor.
One excellent could be founded in http: How to tell how many poles a motor has. The inter-coil jumpers within a group are the same for all groups. For example connect top lead of one coil to bottom lead of the next coil CW.
That must be considered in connecting the jumpers between poles. Assuming there is only one circuit per phase, the simplest way is adjacent pole connection. See here for that thread The powerpoint attached there adjacent pole gives an idea of typical pole jumpers.
Lots of complications and variations possible. The groups in a phase are not always connected in one series path.
A two-circuit winding has two parallels per phase. If I were studying a winding, I would START with the nameplate to determine the nuimber of poles, then look at the winding itself to try to get additional details. There are plenty of the forum that spend a lot more time with windings than me.
Unfortunately the site mentioned in the linked thread uiitraining no longer exists.
Maybe forum member zlatkodo has some info on his site?An engine or motor is a machine designed to convert one form of energy into mechanical energy.
Heat engines burn a fuel to create heat which is then used to do work. Internal combustion engines are heat engines that burn fuel in a combustion chamber to extract work from the pressure of expanding gases. Electric motors convert electrical energy into mechanical motion; pneumatic motors use.

Horizontal Type Three Phase Induction Motor Drip-Proof, IP22 Degrees of Protection Pole: 2 Pole, 4 Pole, 6 Pole Voltage & Frequency: LT Type: Up to 10HP, /[email protected], /[email protected] No just staying with the 3 phase motors for now as they are the most common ones we receive in and work on.
I can do most of the work on the motors at present but it's looking into the stator and checking to see how many poles the motor has is where it ends.
