The gearbox grease has separated and is starting to move (slowly) onto the motor armature area through the front bearing. Replace the grease and since it will be apart, use a lot of cloth strips (NO Q-TIPS! TOO STRINGY - LEAVES A MESS) and alcohol to clean off the motor's armature, housing area and any place you see grease slung around. It's not going to be easy, but worth it. I will try to post pictures as I am doing this right now 12/28/17 to my wife's Kitchenaid for this exact reason.The first image is the gear side of the motor bearing, where the thinning grease is moving through. The second image is a shot of the armature of the motor where the brushes touch and will smoke if grease gets that far (it does). The third image is a cleaned out armature area (brushes removed and speed switch moved)The last is the pooled oil separated and sitting just behind the gear box (where will it go if you tilt the head back?)
When I made the bread dough the mixer little bit shaking maybe it was from the heavy dough and then the smoked come out from the head back of mixer but when I tried it still work.. but I still worry whether it dangerous or not.

Re: My mixer started to smoke!!
If it started to smoke out the back it may just be the motor brush.There are several parts available online I have included one site of many HERE There are a lot of parts sites available you may want to find one close to you.You can check your brushes before you order replacement ones by unscrewing the large black screws on each side of the mixer if there is not much left of the metal portion on the end of the spring that's the problem.Hope this helps you.

Look in the oven, the cake may be burning. If the smell is from the mixer it could be a capacitor burning out, it could be a fault on the PCB, it could be a poor connection in the wiring, it could be a faulty armature, it could be faulty field windings, it could be a bush or bearing nipping up. If it's not amongst that list try getting back with more information.
hi its not necessarily the motor but could be some capacitors on the speed control unit ( the control knob is attached to it) spares are reasonable to buy .you can find a dealer from kenwood.co.uk website..
Hi CHRISTIMARR.It’s never a good sign when you get smoke from an electrical appliance, so yes you probably ruined your motor.You did the right thing by turning your mixer off before any more damage could occur.The best way to determine the full extent of the damage is to disassemble your mixer and get a good look at all the electrical components.Between ‘seeing’ and ‘smelling’ you should be able to find where the smoke originated and what parts potentially need replacement. That being said if you are DITY type person and feel adventurous, replacing the motor is a relatively easy repair you can do yourself. I’ll assume your mixer is no longer under warranty.Be sure you have the Parts List manual on hand. If you're lacking one, you can download it from the KA website http://www.kitchenaid.com/flash.cmd?/#/page/home. Click on Customer Care>Locate Manuals & Guides>Enter the 6 character model number, in your case use KT2651X, and select, KT2651XSG3.pdf (325.07 KB) underParts List (13). (Check to see it this matches your mixer model.) Turn to pages 4 & 5, titled: Case, Gearing And Planetary Unit for the disassembly and reassembly of your mixer, along with all the parts.Locate Illus. No. 2 Motor (10 Tooth), KT Part # 9706548).This is most likely what needs to replaced. But also look at Illus Nos. 8, (Speed) Control Assembly, #9, Hall Effect Sensor, and #30, Motor to Control Lead, which are the other electrical components.Your smoke originated from one (or more) of these four items. Here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; and partstore.com. Prices can vary widely between vendors, so do your comparison shopping. Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers are different models, but the principles are the same.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer, should you decide to go that route. If you feel replacing the motor or other electrical components is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping. And if this still doesn’t appeal to you, remember… Christmas is only 8 more days away! I hope this helps.

Your mixer may still be good, let it cool down and then check it out, If it runs OK then there is no problem. The motor in your mixer probably over heated from trying to mix bread dough which will make any mixer work hard. These mixers will get warm when over worked but unless heavy smoke was coming out and you were getting a burning enamel smell it is probably OK. Let it cool and try it but I suggest you not use it for bread any more.
I'd check the brushes. The big black screws on the side of the motor casing, easily removed, but becareful when you put them back. Here were some instructions from another site that helped me get them back in right:
The brushes in my model KP50PSBU must be insert in a particular manner in order for it to work correctly. If you remove the brushes and shine a flashlight into the hole, you should see a small detent or "stop" in one corner of the hole. Its a square hole. Match this corner with the corner of the brush which is shaved off. The brush is not square; it has one corner shaved or smoothed down. This allows the brush to fully extend into the hole. If the brush is inserted any other way, it will not contact the motor and will not run.
There is the possibility that if the mixer is 30 years old and it has never been serviced that the gasket around the gear case is leaking oil and in that case it would not be hard to get liquids on the armature or the stator as the gear grease in the transmission is vegetable base grease and it separates into liquids and solid and when the head is tilted up the failed gasket allows the separated oil to leak down and to the rear onto the mixer right onto the motor parts. It maybe nothing more that cleaning out all the old grease and re-packing and adding a new gasket.
