| Aug 1, 2019 at 3:32 | comment | added | user80875 | I found a motor that has the same specifications with one difference. Instead of the 3.25 A figure described as the "locked rotor current," it is described as "current with load." I suspect that 3.5 amps is the maximum continuous current. The locked rotor current mat be more like 30 amps. If your power supply shuts itself down or emits a puff of smoke the second you connect the motor, you will know that the motor seller's "specification" is garbage, pretty much the norm for eBay. | |

| Aug 1, 2019 at 2:09 | comment | added | Callum | Thanks for your answer. Is there a safe way to test this at 12 volts? Perhaps by powering the motor for short periods of time with the power supply to see if the motor gets hot? | |
