Wind Turbine using 72vdc HPM5000B

[solardan]

I just purchased a 72vdc HPM5000B to be used on an experimental wind turbine of my own design.

I would like to know what your large wire, color codes are.

They are Green, Yellow and Blue.

I also assume since I am using this motor as a power generator to charge my battery bank, I will not need the small wire connector for anything.

I need to know which wire is positive, negative and ground.  I assume Green is ground!

Please Help.

Thank you,
Dan

Solardan,
Not sure if you realize that this is a brushless 3-phase motor? The wires are for each of the motor phases, no positive, negative or ground here. You need a 3 phase brushless motor contoller with regeneration feature to convert the motor current into a DC voltage.

I believe it does not matter which order you connect the 3 wires for generation. However if the output from the controller has wrong polarity, just swap any two of the wires.

The small wires are for the hall-sensors, I guess they are not needed when the motor is used only for generation.

Good luck on this rather unusal use of the GM motor

No I did not realize that when I purchased it.  Bummer!!!!  I thought it was a 2-pole single phaes unit.  When I emailed Golden Motor and asked them if it would work as a wind generator, they said yes WITHOUT telling me I needed anything else.

Where to I get a 3 phase brushless motor contoller with regeneration feature?

Can I use the Hall Sensor to monitor RPM's in any way?

Thank you,
Dan

Golden motors has a couple of controllers. The BAC-281 Cruise controller can handle up to 60 Volts for driving the motor and it is rated at 50 Amps. Not sure how it will work in regen mode with your 5000W motor though.

It should be possible to measure rpms by using the hall sensors, but I do not know enough to tell you how 

Hopefully others with more knowledge will chime in to sort this out for you.

Dan,

Wiring details for this motor can be found here: HPM5000B

The Green, Yellow and Blue thick wires are the three phase main power wires.

If you're using it as a wind generator you will require six heavy duty diodes  (or a suitable rectifier unit) to rectify the AC voltage produced:



You will probably require some form of voltage regulator to prevent any overcharging of your storage batteries, but you will have to do a bit of research on that.

Thank you!

It looks like I have some more work to do and more parts to buy.  If anyone else can be more specific with part numbers and brand names, I am all ears.

I appreciate everyone's efforts.

I found this: a suitable rectifier unit on eBay.

And some useful info here.

P.S. Surely your username should be Windydan?

Thanks for the info Alan!

I just emailed the guy on Ebay.

My main passion is solar and is why my name is solardan, but during my project here at my house playing around, I decided to try some wind power since I live on a hill.

I am experimenting with geothermal heat pump technology and solar.

When I get my new wind turbine up and running, I will showcase it too.

Dear Dan,

We also supply solar energy boards, multi/mono-crystalline. We can make up to 500MW of solar panels, it's a very huge business indeed. If you are interested please contact me. yaoyuan@goldenmotor.com

Right now I would appreciate knowing what your wire colors mean.

I assume I bought a 72 vdc 5000 watt motor.

A wiring diagram in USA English would be nice too.

What are the following wire colors?

Green?
Blue?
Yellow?

Also, how can I hook up the hall effect wires to read RPM's?

Thanks,
Dan

The three thick wires (which are shown on the diagram as Green, Yellow and Blue) go to the motor windings as per my diagram:

For simplicity I've shown the windings as a star configuration, but the motors may be wired in a delta configuration for all I know.
Either way it will have three heavy duty cables coming from the motor which will need to connect to a rectifier of some sort.
It doesn't matter which colours go to which connection so long as all three go to separate connections on the AC input side of the rectifier.

You should also have five smaller wires:
Small Red would normally have a 5V supply to feed the three hall sensors.
Small Black is the common ground (0V) for the three hall sensors.
Small Green, Yellow and Blue are the signal outputs for each of the three hall sensors.

I don't know how you can use the hall sensors to give an RPM output.

Hope this helps.

Alan,

First of all, THANK YOU for this info.

The part that is disturbing is the fact I bought this motor being told it was a 72vdc and is why I am having difficulty.

The only thing I have not done yet spin the darn thing and take a reading.

I will not be able to do so for a couple of days due to my work but will try on Thursday.

Sincerely,
Dan

I just hooked up a drill motor to the HPM5000B and spun it.
I hooked up two seperate meters with one on AC and the other on DC.

It developed 12 VAC which tells me Golden Motor sold me a bill of goods because I specifically asked for a 72vdc motor.

I will purchase the rest of the items needed to make this work.

Thanks to EVERYONE except Golden Motor.

Dan,

Don't forget this is probably a 4,000 rpm motor that you are using as a generator, it will obviously need to be geared up sufficiently to allow it to spin fast enough to generate power at the voltage you require.

Electric motors have an almost linear relationship between voltage applied and rpm output, so presumably, the same would be true in reverse when being used as a generator.
(rpm applied and voltage output).

I reckon if you're getting 12 Volts (with no load) driving it with a drill, it should generate 72 Volts if you spin it 6 times faster than the drill.

If you knew how fast the drill was spinning, it would be easy to calculate how fast the motor needs to spin before it starts to produce power (current flow) at 72V.

Please let us know how you get on with this rather interesting project.

I will definitely keep in touch.

Y'all have been great.
