Building a goat milking machine but having trouble getting beyond the Protech
gearmotor and the SCR (specs below).
My issue: the Minarik SCR MM23001c seems to need/require additional
components to function properly. I bought the Protech and Minarik from
surpluscenter.com. The gearmotor was actually cheaper than the Minarik SCR.
The Minarik SCR needs a line fuse pg.18.
Minarik drives require an external fuse for protection. Use fast acting fuses
rated for 250 VAC or higher, approximately 150% of the maximum armature
current.
and line filter pg 69,
If the exact line filter is not available, the specifications are as
follow:
L= (1.73 + 0.03) milliHenries.
C = (0.27 + 0.54) microFarads (X); 0.0055 microFarads (Y)
R = 330Kohms.
Rated current: 1.4 times maximum DC motor current.
Filter type: Balanced 2-section.

Can anyone recommend a line fuse and line filter for me to use besides the
Minarik brand, or can someone recommend a different SCR that I could use that
would be easier to install, or at least comes with line fuse? My concerns is
that I am going to end up spending more money than necessary to get my current
SCR to function properly with the gearmotor below.
Gear Motor:
Protech 250 RPM 125 VDC RA gearmotor
Amp: 0.5, 1/12 HP
Thanks
