#26119 How to draw 220V motor
Posted by Bill E. on 30 March 2012 - 12:34 AM in General Discussion
Rookie, exactly what do you want to do with the 220V (AC I presume) 100W motors? Control their cycle time or speed? Cycle time can be done with triacs (for a reasonable duty cycle period like on for 10 seconds off for 10 seconds) but if you want speed? Now that's more difficult. Magpie hit it on the head that if you want to control the speed of the motors. PWM is all about effective energy delivered to a load. Using PWM with AC (50/60HZ) just doesn't compute. You need DC motors to work with PWM - on vs off time.
A solar system, I would think, doesn't need milisecond or even second control. If I were you I would think about a NUCH hegher repetition rate line MINUTES control of the pumps. Simple monitoring works then.
Peace,
Bill

#17419 Vibrator Circuit - Need Help

We aren't that much different than the lower 48. We just have longer winters and shorter summers. Winter typically starts mid September and runs till mid April Oh, and its dark here, at the winter solstice the sun comes up around 10:30 and sets around 3:30 .
When you come, come in the summer time. June is a good month, not to hot, its usually pretty sunny. August is the worst time, it rains almost every day. In fact, last year it rained every day for 36 days in a row
As to being a PITA on the mains issue, I don't think you are. People need reminders sometimes that the mains can hurt you :-)
