Rankine rotary expansion generator. David Wells and I have discussed the use of these expanders for use in Rankine engines. Here is my concept. Take a Copeland Scroll Compressor complete with its 3 phase induction motor almost off the shelf.
|Lecture notes on Single Phase Induction motor||However, the flux estimation is usually based on the integration of the motor phase voltages.|
|Latest News||Terminology[ edit ] The word engine derives from Old French enginfrom the Latin ingenium—the root of the word ingenious. Pre-industrial weapons of war, such as catapultstrebuchets and battering ramswere called siege enginesand knowledge of how to construct them was often treated as a military secret.|
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?The modeling of the single phase permanent capacitor induction motor projects the non-linear model of the system.
Here to inject non linearity the capacitor is connected to the main winding instead of auxiliary winding and the inductance value. Oct 13, · When using a 3-phase motor and a bi-metallic overload is it recommended to use the internal Variable Frequency Drive overload protection?
Does the internal VFD overload protection change with as the motor speed/amps change? i ABSTRACT This thesis presents a new technique to develop an air-conditioner (A/C) compressor single phase induction motor model for use in an electro-magnetic.
