Re: 3 Phase 110 VAC 1/4 horse power motor

Thank You Mr. Reed, and to everyone that has reponded. Tuesday I will check the motor, and if it isn't 110 1 phase we will replace. We know a new motor size will generally fit, but we're not expecting a drop in replacement. However a third friend, also involved in this small project, is a machinist ...

Re: 3 Phase 110 VAC 1/4 horse power motor

There is no documentation to post or link to manufacture, it's some
where in India, I agree with more doc's all that would be great.

What I have is a motor with three wires and a lable that says 3 phase 110vac.

But Thanks for the input MrAl.

3 Phase 110 VAC 1/4 horse power motor

A artist friend asked me to look at a motor he bought from India that is labled 3 Phase 110 VAC 1/4 HP. It has three wires coming out of the body. When it was ordered there was a lot of confusion about the voltage and he thought he was getting a 110 VAC single phase motor. Searching the internet it ...

Re: Voltage converter

Thanks ALL, appreciate the information and direction.

(This is for a voltage that will vary between 0 and 5.)

Now I just need to find the box that has those op amps
in and build a test circuit.

Voltage converter

Can anyone suggest a method or methods for converting a incoming 0-5 vdc control voltage
so there is the opposite voltage direction. When input is 0 output is 5, input 5 output 0.

Re: Ipod Nano in the washer.

Thank Edd. I figured out how to open the little beast, and it was the same as you wrote. However, I made little wedged picks out of 1/8 diameter bamboo sticks that were in the kitchen drawer. They worked fine, were strong enough, and the bamboo is easy to cut to various thicknesses. I started at one...

Re: Ipod Nano in the washer.

I agree and have flushed it alcohol and put it in 100 degree F oven. The problem is how to open the case and not damage it. Since this is a relitively new product there is not a lot of DIY info out yet. Thanks for your suggestions.

Polar Heart rate monitor hack

Has anyone hacked the audio code on Polar heart rate monitors or have any ideas on how to do it? I'm thinking something that uses PIC basic. They use a audio tone signal and your sound card mic input to uplink data. Their new product can only be uplinked to their website for viewing data and it woul...

PWM frequency selection

When using PWM to drive an H-bridge and motor, what criteria is used to select the duty cycle and frequency? The system is a PIC processor and LMD18200, driving a 24vdc gearmotor and lifts a weight up and down. <p>THX
