Three Phase Motor Connection Star/Delta (Y-) Reverse and Forward with Timer Power & Control Diagram

As we have already shared the Starting method of Three Phase Motor by Star Delta Starter with Timer Circuit (Power and Control Circuits). Now in the below diagrams, Three phase Motor will rotate in two directions viz Forward and Reverse. But We have controlled the direction of rotation of this three phase motor by a Timer circuit.

Abbreviations:O/L = Over Load RelayNO = Normally OpenNC = Normally CloseFOR = ForwardREV = Reverse T = Timer

I have almost forgotten what I was told in the late 90s

I am one of those electrosensitive people and much of what basic science says about new technology is wrong.

Different names have been used which confuses..

Brushless motors inverters particle accelerator free energy devices zero point energy reverse technology motor.

Transformers have been replaced with these devices.

That means wind turbines air con systems solar panels

Computers and mobile phone dont comply to EMC EMI and human exposure to electromagnetic fields.

The U.K. Government removed Radiocommunications agency and BTs equivalent in 2002 to save money.

Trading Standards OFCOM and (TV detector vans)

have not a clue.

There is nowhere to report the problems too.

I contacted Central Networks some years ago and told them that technology was not complying to the Law.

They said it was the governments fault.

The above devices produce power surges in the mains supply the transformer is either taken away or reduced in size to allow the device to generate more power off scale. The electricity companies can check the mains down to 20Hz they use to rely on Radiocommunications checking for radiation below this. As it is there is not much done about power surges below this. They delt with military and civilian technology. There is no one measuring military technology.

Confusion between low frequency or a different phase

Or polarity has confused.

Truly there is no such thing as frequency.

The aircraft industry are well aware.

The Mod complained about wind turbines interfering with RADAR the government took no notice. The Mod then turned the power up on the RADAR.

Its apsolute hell living near a factory or supermarket.

The air con gives of huge levels of noise.

I spoke to London Underground and network rail they regonise there is a problem with talk back. But the government have removed the legislators and left the legistion. Industry is not going to cut its own nose off.

This radiation causes inverted T waves in the heart.

Which cause heart attacks and strokes.

Dr Henry Lai.. Its also effecting the environment.

The Mod gaged the police when they complained about the radiation from their radios called Tetra.

What price for so called new technology.
