cctransuk Posted October 28, 2016 Share Posted October 28, 2016 Due to the closure of Mashima, I have had a considerable increase in the number of orders for my Mitsumi motors - see http://www.cctrans.org.uk/ and http://www.mitsumi.co.jp/latest/Catalog/compo/motorav/m15n3series_e.html - and stocks are running low. In order that I may determine whether to restock these motors and, if so, how many to order it would help if any member who has, or is likely to have need for these motors to either order ASAP or to notify me of the extent of their anticipated requirement. In the latter case, a simple PM or an e-mail to cctrans@hotmail.com, indicating your anticipated requirement during, say, the next twelve months would be appreciated. There would, of course, be no subsequent obligation to purchase. Many thanks in anticipation. Regards, John Isherwood. 1 Link to post Share on other sites More sharing options...
PenrithBeacon Posted December 13, 2016 Share Posted December 13, 2016 It's interesting that both LRM and High Level are still quoting Mashima motors on their websites. I know that LRM don't have any because I've had an email conversation with John Redrup on this matter. I wonder why the kit manufacturers aren't going over to Mashima.

davefrk Posted December 13, 2016 Share Posted December 13, 2016 Had a try of one of these Chinese motors off ebay, not particularly impressed.... not much torque at low revs where we need it. Matched with a decent gearbox like HighLevel they might be okay for light use but I'll be sticking with Mashima's for the next wee while until something else appears, there are other manufacturers of quality motors out there. Been using Sagami and Mashimas cans for over thirty years and never had a failure. Mashima's are still available from a number of stockists. Dave Franks.

Crantock Posted December 13, 2016 Share Posted December 13, 2016 I have a bunch of Mitsumi's as above which come with a spur gear at the end. So can anyone suggest a decent gear puller? I have bought the Expo version https://www.expotools.com/acatalog/Minature-Gear-Puller-26241.html and have never bought anything so utterly useless. There are 2 faults. Firstly the angle on the outside of the jaws means the shaft is never going to be at 90 degrees to the push rod. Secondly, neither of the 2 push rods were straight. The combination is useless. I understand why I have never seen them on traders stands at exhibitions. I hope its not too o/t but as you can see from the thread there are a lot of motors need de-gearing as step 1.

I had some gears to remove for a colleague and found that my 'GW' puller wouldn't look at it. Put the brass gear in a vice and squeezed hard, turned 90' and squeezed again, the soft brass gear almost fell off.... All five done in a few minutes. HTH.

Dazzler Fan Posted December 15, 2016 Share Posted December 15, 2016 (edited) Some of these can motors, as I posted above with a gearbox, are used in professional video equipment. I don't think they can all be junk. If Mashima are so good, I am surprised the Customer List, Tooling and Rights of the business is not bought by a competitor. We have seen this happen too often as generations change. N. Edited December 15, 2016 by Dazzler Fan Link to post Share on other sites More sharing options...

We have seen this happen too often as generations change. N. Apparently the supply of magnets used by Mashima had ceased. The tooling was reportedly also getting to the end of its working life. Mr Mashima also wishec to retire. Such things do happen and, despite the economic opportunity apparently afforded by taking over the role of supplier, few people are willing to do it.

Petri Sallinen Posted December 15, 2016 Share Posted December 15, 2016 (edited) Mashimas have very good quality and they work well, but they are also expensive. You are able to buy three pole Mitsumis under one euro, but the price of five pole Mashimas is typically almost ten euros or more. Technically five pole Mashimas are better than three pole Mitsumis, but not ten times better. In many cases three pole Mitsumis is enough for giving good running for locomotives. That´s why massproduction locomotive models have cheaper motors than Mashimas. I have used coreless motors like Maxon or Faulhaber in many models and also in many kits we have produced in Finland. In my personal opinion Maxons are one of the best motors I have every used — they are small and powerfull and silent and they work extremely well when you are driving slowly. But they are also very expensive — about 30-50 euros depending on how many motors you are buying at once. Typically enthusiasts are not ready to pay 30-50 euros extra price for getting the kit with coreless motor — Mitsumis like motors are typically enough for most of enthusiasts, especially in DCC times. You are able to test this by producing the kit with alternative motors choice — 15 euros extra price for Mashimas and 50 extra price for Maxons. Here is the underframe of Finnish locomotive kit with coreless Maxon — too expensive for most of enthusiasts. Underframe with Mitsumi like or Mashima like motor is typically enough.

The 3 pole Mitsumis may be fine for DCC but what about those of us who run DC plus like the convenience of using Highlevel gear boxes with easy fixings etc. I guess its a case of wait and see what alternatives crop up from the gearbox suppliers Link to post Share on other sites More sharing options...
