Les73gtx Posted October 1, 2014 Share Posted October 1, 2014 Hey guys, Just a heads up about a good deal on the same shaker motor that Stern and others use in their machines. On eBay right now and there are 10 left ... the price is $8 but I was charged $20 in shipping from Florida to Maine 3 day ... not bad if you ask me. I will have it tomorrow and give some measurements and other info if needed. http://www.ebay.com/...=STRK:MEBIDX:IT Enjoy Link to comment Share on other sites More sharing options...

Spektre Posted October 2, 2014 Share Posted October 2, 2014 Les, are you planning on putting weights on the shafts for vibration. Frodus, any experience with these particular motors? Link to comment Share on other sites More sharing options...
frodus Posted October 2, 2014 Share Posted October 2, 2014 Not with those particular products, but I've bought a ton from surpluscenter and most has been decent quality. Mostly OEM level stuff, excess stock/surplus. Mine has always been brand new, unused. Link to comment Share on other sites More sharing options...
Les73gtx Posted October 2, 2014 Author Share Posted October 2, 2014 Les, are you planning on putting weights on the shafts for vibration. Frodus, any experience with these particular motors? Yes I will be making something to weight the shaft .... I have received it today and it seems to spin around 3000 rpm Free spin and has good start up torque. Seems to be a new unit as there was no marks on the com or connectors or shafts. I clicked on the link to make sure it was still there and I see he raised his price to $12 with $21 shipping .... still a good deal I think. I will be making a mount that utilizes both front mounting holes and also a clamp of some kind. I will not have any time to work on it till this weekend.

Spektre Posted October 11, 2014 Share Posted October 11, 2014 Any updates? A word of caution using that HC970 from ebay Les, the datasheet says the motor has an 84A stall current. You'd probably blow out even one of Zeb's booster board channels. Link to comment Share on other sites More sharing options...
Les73gtx Posted October 14, 2014 Author Share Posted October 14, 2014 Hmmm that is something I missed .... no updates as real life and a Mame cabinet build has taken up my time for now ... thank you for the heads up ... I also found some information someplace (don't remember where) that there are many different versions of this same HC970 running different RPM's and power requirements.

Les73gtx Posted October 14, 2014 Author Share Posted October 14, 2014 I found this while looking at it again ... I believe this to be the one I have inhand. http://www.sciplus.com/p/JOHNSON-DOUBLESHAFTED-12VDC-2900-RPM-MOTOR_51787 This is a nice site also ... cheaper than what I paid ... dunno about shipping .... The relay board I have will handle 10amps ... and the secondary PC Power supply is a 500 watt with 3 - 12v rails @ 12.2 amps each I believe ... I will build something in the next few days as I am waiting on some parts for the Mame Cabinet. Link to comment Share on other sites More sharing options...
Spektre Posted October 14, 2014 Share Posted October 14, 2014 As long as nothing physically stops the motor, it won't draw stall current for long. But that seems higher than I'd want to throw at a booster even transiently. Link to comment Share on other sites More sharing options...

The HC970 seems to be a series number instead of a part number. Link to comment Share on other sites More sharing options...
Les73gtx Posted November 3, 2014 Author Share Posted November 3, 2014 Well I started late last night to work on this .... I will get on it for the next few days and get it done. Link to comment Share on other sites More sharing options...
Les73gtx Posted November 4, 2014 Author Share Posted November 4, 2014 Progress for the night .... just need to bend me a shield for it tomorrow, gonna use the same aluminum diamond plate. Total cost ... $45 Link to comment Share on other sites More sharing options...
Les73gtx Posted November 5, 2014 Author Share Posted November 5, 2014 Installed and working great ... I had to use the config tool for turning down the intensity of the shaker ... now set 5 min to 20 max ... I might go a little lower than that on the max Overall I say this was a great success as it really feels very close to the modern Stern tables like Star Trek and Mustang. the old shakers are behind the gear motor on the left and the box with the solenoids are for the slings ...they were a bit too loud even at 5v. New shaker assembly would not fit where the old one resided so 2 problems solved ... location for new shaker and softer slings. Link to comment Share on other sites More sharing options...
Les73gtx Posted November 5, 2014 Author Share Posted November 5, 2014 metal bending the shield will have screws into the wooden block on sides and more for the mounting this thing should be stable. Link to comment Share on other sites More sharing options...
Spektre Posted November 6, 2014 Share Posted November 6, 2014 Looks great. Do you have a capture DMM or Oscope to see what the inrush current is? Link to comment Share on other sites More sharing options...
Les73gtx Posted November 6, 2014 Author Share Posted November 6, 2014 Looks great. Do you have a capture DMM or Oscope to see what the inrush current is? . Unfortunately no I do not have either ... but the wife and I have been playing all night and no issues at all ... even during the Martian Attack in AFM where it runs for extended periods of time, it is cool to the touch and everything runs smoothly.

Les73gtx Posted November 6, 2014 Author Share Posted November 6, 2014 . . Here is the relay board that I am using. Best 25 dollars I spent in a while. Lol Link to comment Share on other sites More sharing options...
Spektre Posted November 19, 2014 Share Posted November 19, 2014 Les. Where did yo get the tapped screws yo uare using for weights on this? Good idea and I might go that route instead of the bore hubs I was considering. Link to comment Share on other sites More sharing options...
DJRobX Posted November 20, 2014 Share Posted November 20, 2014 Yeah, I like the tapped screw idea also. I'm using bore hubs now. While they have a nice feel, I think they have too much overall weight, so I think they 'delay' (slow ramp-up) the effect too much. Before the hubs arrived I used some wire clamps. They resulted in more responsive shaking but weren't quite heavy enough. Link to comment Share on other sites More sharing options...
Les73gtx Posted November 20, 2014 Author Share Posted November 20, 2014 Well honestly, I went into my box of bolts from years of working cars and found a matching set. I made another set for someone and included the extra nuts in case your personal preference required more weight . . Was able to settle on 5 min and 18 max in the config tool.

Content Provider edizzle Posted March 14, 2015 Content Provider Share Posted March 14, 2015 Hello Les, So you controlled the intensity of the motor strictly with the DOF min and max settings? You did not add a dc motor speed controller unit? I have a similar Johnson HC 970 motor and I think I will try to find tapped screws such as you did. Nice idea.

Hey edizzle1, Nothing added and yes I am strictly using the DOF config to control intensity. I am happy to report that after every day playing for the last few months this setup is still working wonderfully. No power supply issues or any kind of failure at all. Completely satisfied with this setup. Thanks for the compliments everyone and glad I could give back by sharing my ideas. Link to comment Share on other sites More sharing options...
Content Provider edizzle Posted March 18, 2015 Content Provider Share Posted March 18, 2015 excellent. Thanks for the information. I will forgo purchasing a separate motor controller then! Link to comment Share on other sites More sharing options...
