Bosch GTS10 - motor rebuild

[kmcleod]

Hi all,,,

My Bosch GTS tablesaw died on me last weekend,

Have checked the plug, switch etc and it is definately the motor that is dead !!!!

Does anyone know where i can get instructions for rebuilding one of these, as you can purchase all of the parts, but not a complete motor.

Thanks

If the motor is burned out then it will need a rewind and probably a bearing change. This is not really something that can be practicly done at home. It involves taking the casing off cutting out the crown of the windings, getting the right thickness of wire and rewinding the coils by hand.

If you can't get wire that matches then you need to calculate what combination of wires are needed to match the original. After that wind the coils by hand on a jig. Any scratches in the coatings on the wire will cause a short and its back to square one.

This is the simple explanation. There's a few other things needed like insulating the finished coils etc...

I did loads in a specialist workshop back in the day...

A motor repair shop / armature winders will be able to do it, but it may be cheaper to swap the motor if that's possible.

Hi Dav,

I can get the spares, problem is more fundamental than that - there is no instructions on how to disassemble and then put it back together.

Plus they dont sell the motor as a single unit so you have to but all the bits and put it together, which is damn near the cost of a new saw.

So left with situation that if I cannot find some documentation I may have to bin the saw, and either buy a new one, or reconsider the need for a saw completely, and maybe go down the bandsaw route.

what bugs me, is that as a guy doing woodwork for a hobby this saw hasnt exactly been overworked, so expected it to last a good bit longer.

ISTR that this saw has a brush motor, It maybe something as simple as new brushes.

I've never seen a saw of any type quality that gives instructions for rebuilding a motor. There are often exploded diagrams on the spares stockists website which will be about the best you can get.

I think Bosch do repairs - might be worth an enquiry if you don't feel competent to do it yourself.

Just take it apart it’s not rocket science. It could be a wire come unsoldered it happens with bosch tools. It pays to buy a table saw with a belt drive motor.

I would love a table saw with a belt drive motor, and a cast iron bed and lots of the other sensible stuff that comes with a good table saw that sits in one place all the time, but my workshop is a garage, and when i am not building something, it all has to be packed away so a car can be parked in it, so the GTS10, more or less fits the bill because it gets me there or thereabouts and I can still pick it up to pack it away.

Car in the garage :shock:

yep, i know, alien concept on here, but the other half would prefer it, so not a lot you can do,,,

nice to see the usual considered decent responses on here haven't in any way declined over the passage of time.

Pete is still posting inane stupid comments, and not facing the reality of life that most of us on here who are married are pursuing a hobby/interest and have to work within the constraints of limited space / limited time and not pissing off the entirety of those around us, both family and neighbours.

If 'grow a pair' is the most constructive and helpful comment you can make, then dont bother making the effort, others on here have been helpful and constructive - here's a hint - FOLLOW THEIR EXAMPLE

Well it was meant as a joke, note the wink.

Marriage is a partnership so both side have to give and take, if you need more room in the garage leave the car out, it probably spends most of the day out side any way, this would give you space to pursue your hobby, but if your wife won't let you then I feel sorry for you.

Have the motor checked out its either the brushes, stator or rotator not the whole motor that is defective, and get in touch with Bosch if it has only been lightly used they might be able to help you.

You don't need a manual to repair an electric motor, we did hundreds a year and I never saw a manual. Take all the measurements off the job. Rewinding motors if that's what it needs is fairly specialist IMHO.

If it's ac and I am guessing it is, it may be a universal with a commutator and brushes or it will have start windings that switch out centrifugally when its up to speed and the main coils switch in.

Ask for a quote for a repair from a winder shop or treat yourself to a new saw.....
