You may have a motor winding lead that has touched the case of the motor, shorting out the windings, drawing too much amperage, thus blowing fuses. You may have to disassemble your motor and check the stator windings for a short as well as the armature windings. Also the motor could be hanging up due to bearing trouble and causing the motor to draw too much amperage. Probably the cheapest thing to do would be to replace the motor.

before you replace it, you can try and clean the commutator. To do this first unplug the tool and turn the saw on its backside. remove the brushes and find a emory board (cardboard) while turning the blade by hand (use a glove) lightly touch the board to the commutator to try and clean the surface, While doing this try and notice any raised sections of the comm, if there are any then you would need a new armature and possibly field. I would try cleaning first though. Let me know if you have any more questions.

there are no capacitators that I see. What I would do is unplug the tool and remove the brushes and check there condition for burning/wear and if you can look into the brush tube and carefully turn the motor by hand and look at the commutator for discoloration. Let me know if you need more help. You can download a breakdown at "makitausa.com"

sounds like a faulty switch. before removing write yourself or take a photo of where the wires go. Also check the condition of the brushes, if they are too short the brake won't work either.

if the motor RPM drops dramatically when the noise starts, it is probably a dry motor bushing, if this just started, lubricating the motor may just fix it.

All portable power tools including saws and most tradesman type saw benches use the light and powerful series wound brush-type motor that doesn't use a start capacitor. The single phase induction motor that does use a start capacitor is far too bulky and heavy for portable tools but is found in many of the static workshop tools. The powerful brush type motor is electrically very noisy and is almost permanently at the edge of self destructing. Good suppression to prevent radio and tv interference is necessary and this also helps protect the motor but a mains transient or power surge while in use can cause an internal surge destroying the insulation of the windings rendering the motor useless in a millisecond. This could be what happened to your saw though it could equally be an internal short circuit in the power cord or inside the saw and these things must be checked before either writing off the tool or sending it for repair.

The principle of the series wound brush type motor is fairly straightforward with a field coil set either side of an armature that is mounted in bearings with a commutator and brush gear mounted at one end, the circuit consists of a field coil, the armature and the other field coil connected in series. The air gap between the rotor and stator is small but large enough to allow free rotation even when hot - electrically there should be continuity through the circuit from the start of one field coil to the end of the other though typically the dc resistance will be found to be low but will rise sharply when the armature is spun... The checking of the wiring, switch and motor circuit is largely intuitive and well within the scope of the handyperson though the proper testing of electronic speed controls or soft starts is beyond most folk, fortunately though, these things are usually in the form of a module that either work or don't and if the remainder of the circuit tests ok it is reasonable to assume the module is defective and it is usually reasonable to bypass such a module to test motor operation before spending cash. Professional equipment sold in many parts of the world must be fitted with an electric brake designed to stop rotation in one second when switched off - as yet I haven't had to delve into such things. This design of motor is electrically very noisy and high powered motors are perpetually at the edge of self-destruction and effective suppression is important to prevent electrical interference to receiving equipment and to some extent protect the motor. Suppression takes on a variety of forms from a through-module containing a variety of chokes and capacitors to discrete components. It isn't unusual for a suppressor module to fail - they often don't age well...
