Questions on 387 motor specs

[george4657]

I would like to get the new 318 ozin motor but my time line requires delivery within the next two weeks.
In comparing the spec sheet for KL23H284-35-4B (387) with the spec sheet for KL232100-35-4B (318) I see both at 3.5 Amp and 2.8mh which would imply the same maximum voltage. Also the 318 is bigger than the 387 so why is it rated at a higher rating?
An old spec sheet that I have for the 387 shows it at 4.1mH which would result in a higher voltage and explain the greater max torque.
Which is the correct value?
At 50V and 3.5 Amp how would they compare in speed and torque?

The web page shows the 387 in stock. Can I from this be sure that I can get delivery of 3 right away as I can not afford a delay?

Thanks for your help
George

Hi George! The 387 is the larger motor and 4.1 mH is the correct inductance for it. Only Keling can tell you for sure what is in stock:
