Sick and Tired of Waveline pumps

[RDNanoGuy]

You can't run a dc pump directly off a regular power supply. The controller actually switches the coils in the pump on and off very rapidly in a pattern to get the magnet in the middle to spin. Without the controller the motor will make about half a revolution and stop. It is more like an a/c motor in that respect.

I wouldn't recommend a trial & error method of determining polarity for a motor. Not likely that anything bad would happen with 24 volts, but not worth the chance really. Try to determine polarity with your multimeter. As mentioned earlier, if the signal from the controller is some sort of pwm or pulse, an oscilloscope is the best way to detect that, but the multimeter should react by jumping off zero. If you have an old analog multimeter, you may be able to see the needle move. It will either jump in a positive direction or try to hit the stop at the left of the meter display.

I asked in an earlier post if you could determine whether the motor is a PMG (permanent magnet) DC motor. If it is, it should run on straight DC voltage no problem, this is how all the little 12vdc cooling fan motors work. The coil circuitry design of a PMG DC motor is such that the voltage is switched internally to keep the rotor moving. However, on a low cost product such as the Wavelines, it will be next to impossible to find out more details on the design. Even more established companies producing higher cost hardware are unlikely to be very free with their design information. Best of luck with this endeavour!

Please do not wire the power supply to the pump directly!

Send us your serial number and we will warranty the pump.

THE WAVELINE PUMP CANNOT BE WIRED DIRECTLY TO A POWER SUPPLY AND BY PASS THE CONTROLLER. THE DRIVER IS IN THE CONTROLLER AND YOU CANNOT BY PASS THE DRIVER. IN ADDITION THE CONTROLLING SOFTWARE IS IN THE CONTROLLER, WITHOUT THE CONTROLLING SOFTWARE NOTHING WILL WORK.
