    Sanyo Denki contact or part number help

    My CNC has a Nema 34 stepper for the Z axis from Sanyo Denki. The part number on the stepper is SH2861-5142.
    In the catalog there is a SH2861-5141, but the mH inductance is 3.7 which would be a crazy voltage.
    There is a SH2861-5241, but the current 6a instead of the 4a on the stepper.
    I can't find an email or tech support phone number to follow up on it.
    The CNC was built in late 2019.
    Anybody have a suggestion?

    Steve.

    The SH2861-5141 spec is here.
    https://products.sanyodenki.com/en/s...2/SH2861-5141/
    Sometimes the number might be for a slight variation (eg longer shaft or something)

    With a Sanyo Denki, I would not worry too much about inductance. Just give it a decent voltage and it will fly! I have some 2 amp 60 mm (NEMA 24) motors and they are amazing. They do 40 m/min rapids and 0.8 G acceleration on my machine. But I am feeding them 90 volts.
