60Hz to 40Hz transducer
60Hz to 40Hz transducer
(OP)
Dear professionals
I need to build a power tranducer to drive a eletromagnetic buzzer.The residential electricity in USA is 110V 60Hz, I need the output to be 110V 40hz in square wave with with limited output current.
How can I get the transducer, please help, thank you in advance.

How did it fail to meet your needs?
Which course is it for?

If so, there should be a suitable driver (not transducer) available for it.
Mike, all odd questions aren't necessarily school work.

Half full - Half empty? I don't mind. It's what in it that counts.

OR
2: Rectify it to DC, then switch it on/off. You may need to insert a transformer before the rectifier to get the output voltage correct. You'll need a solid state switch to live with the duty cycle.
You probably won't get square wave voltage with the buzzer connected, because its inductance will fight you. Of course, that's a guess, because you haven't told us squat about the buzzer, e.g., its DC resistance, current demand, power demand, whatever.

The total amount of buzzers is about 100 pcs. So the average power consuming maybe more than 300w, and the average current maybe more than 2.5A, the instantaneous current maybe higher.
Because the system is single frequency working, I'll try to conjugate match it.

Now, if you need 40Hz at 115VAC, I suggest that you take a Variable Frequency Motor drive, and set it to produce 40Hz, or hack a true sine-wave analog-circuit inverter to substutue a 40Hz reference instead of the 60 Hz reference. You might also take one of the microprocessor-based AIMS inverters and substitute a crystal that is 2/3 the frequency of the existing crystal and get it to produce 40 Hz.
