Description:
This replacement armature assembly is a genuine Bosch part, not an aftermarket alternative. It is specially manufactured table saw electric motors. Armature is one of the key components of an electric motor. Over time it will wear out and will need to be replaced. If you notice smoke or sparks coming from the vents on the back of your tool, most likely the tool was overloaded at some point. It is advised to replace both carbon brushes when replacing an armature, this will help to keep extend the life of the new assembly. This assembly includes the armature and the fan. Please note, the bearings and other parts are all sold separately.

To complete this repair you will need a screwdriver.

Questions & Answers

armature for table saw bosch 4000 what are the dimension of this part and is it used on the ridgid table saw model ts2400-1. It looks like the same one.
michael for model number bosch 4000 table saw.
Hello Michael, Thank you for the question. Very sorry but we do not have the dimensions for this, but this part does appear to be a match to your model. Hope this helps!
My saw began blowing blue arcs out of the end of the motor. I replaced the brushes still doing the same thing could it be the field or should I replace or have the armature rewound?
Mark for model number Bosch 4000 table saw
Hi Mark and thank you for contacting us. Remove the field and armature and inspect for burn marks and melted insulation on the windings. If anyone of these is present then replace the bad part. Also, check that there is no debris in between the communtator bars if there is use a plastic scribe to cleanout. Make sure all bars on communtator are present. There is 3 test to use when checking an armature. The first is a continuity test. With the armature removed from the unit. Stand it up on a bench. Attach one end of the OHM meter to the shaft for ground and the other to the bar on the communtator. Move the probe to each bar on the communtator checking all the bars. If the OHM meter shows reading on one of the bars this will indicate a short and a bad armature. Test number two is a bar to bar test to determine the resistance. Attach one probe to a bar on the communtator and the other probe on the bar right beside it. There will be a specific reading for this depending on the design of the armature but most importantly is that there is not a large fluctuation here between the values which would indicate a fault. If there is an increase in resistance this will indicate there is a broken or burned out wire in the coil. If the resistance drops then there is a short. Move around the communtator checking each bar. The third test is the 180-degree test. Attach the 2 ends of the OHM meter on the communtator bars directly across from each other. There will be a specific set of readings for this depending on the design of your unit. Once again what is most important is that there is not a large fluctuation in values which would indicate a fault. If there is an increase in resistance that would indicate a broken or burnt wire. If the resistance drops that would indicate that there is a short. Continue this test on all the bars. If an armature fails any of these tests it is recommended that you replace it You can check the condition of the field by performing a couple of tests. Using a multimeter you can check the field for continuity. Set the multimeter to OHMs and place a lead on each end of the coil in the field. You will have to perform this test for each coil in the field. If the reading is infinity for 1 or more of the coils then the field is bad and requires replacement. If there is a major variance between the coils then the field needs to be replaced. Hope this helps and good luck with your repair.
Saw blade runs backwards slowly when you turn it on. Will replacing the Amature do the trick or will more need to be purchased?
Ben for model number 0601B13010
Hello Ben, thank you for your question. It sounds like an issue with the polarity of the motor. I would recommend replacing the field first and if that doesn't fix the issue the armature next. I hope this helps!
how do i remove armature from the saw itself ? does it pull straight out ,o ?r are there other fasteners ?
Jack Silvia for model number 401474 9504
Hi Jack and thank you for your inquiry. I do not have exact instructions for your model but you can follow along on the page with the blow-up of the motor as to what you will have to do. You will have to remove the cover (part #154) to the motor Remove the cap to the motor (part #22). Remove the brush holders and carbon brushes (part # 16 and 10) and remove the motor housing from the unit. The armature will just pull out. Reverse the procedure to reassemble Good luck with your repair and I hope this information is helpful.
I want you to know that the Bosch armature does work on the ridgid tables model ts 2400-1. I put it on myself and it works .well. to bad ridgid will not share this info. I guess they just want you to buy new saws.please pass we word.
Michael irizarry for model number Bosch a mature 40000
Hello Michael, thank you for your inquiry! We will make this information public so that people can have access to this as well. Thank you.
Can this armature be used as a replacement for for rigid TS 2400
John
Hi, sadly we cannot recommend another part to replace John. Even small differences can cause a part to be incompatible with your model and finding parts other than what is recommended by the manufacturer is outside of our scope of support. Thank you for your question and good luck with your repair!

Tool Type:
Table Saw
Parts Used:
Armature - 1619PA5591
Repair Difficulty:
Medium
Time Spent Repairing:
1-2 hours
Tools Used:
Screwdriver, Allen wrench, vise, bearing puller
Motor had very little torque, no cutting power. I had already replaced speed control and field windings.
To get the arbor side bearing plate mounted correctly, I had to take off the table top, and gain more visibility into the underneath section of saw. I had done this before, and somehow it was harder this time. A metal plate has to be properly positioned as you thread screws onto it. The bad part is you are running 1.25" screws (approx) through a motor housing, and have to hold the plate with a bent coat hanger or something like it, to get the screws started.

The vise and the bearing puller came in very handy for getting the bearings off old armature, without harming them with a hammer or vise grips.

You will be well served to record where the various sized screws came from, and have a magnetic bowl.
