| Jun 10, 2022 at 8:30 | comment | added | Bruce Abbott | "Do I have to choose one with a lower rpm?" - yes. Or a motor designed to run on a higher voltage, eg. 12V, 24V or 36V (the higher the better). Inkjet printers and hair dryers often use a DC motor in this voltage range. Here's one that only needs 460rpm to generate 3V ebay.com/itm/264924712999 | |
| Jun 10, 2022 at 8:05 | comment | added | tlfong01 | So I have set up two JB370 DC Motors. (1) The first motor is driver by DC 12V. (2) The shaft of this first motor is coupled to the shaft of the second motor. (3) The first motor and second motor move at 70rpm. (4) The second motor after 100:1 gear ratio will move the internal motor shaft at 7,000 rpm. (5) Now I need to use a DVM to measure the AC voltage output which I expect to be 12V AC rms.

| Jun 10, 2022 at 6:32 | comment | added | tlfong01 | I searched my junk box and found a JB370 motor which I think has a gear ratio of about 100 and 70rpm. So I think the no gear speed is around 7,000 rpm. Reference: (5) How to use motor drivers with H-bridge and PWM input, to control direction and speed of DC motors? Asked 1 year ago, Viewed 2k times electronics.stackexchange.com/questions/510755/… Appendix B - PWM Controlling Speed of JB37 Geared Motor Geared speed ~= 70 Gear ratio = 100 No gear speed ~= 70 x 100 = 7,000 rpm | |

| Jun 10, 2022 at 2:46 | comment | added | hello_world07 | I tried to use a small Dc motor as well but it didnt work. Do I have to choose one with a lower rpm? | |
