Servo motor burnt out

I operated this servo motor at 8v and full speed for 5 or 10 minutes before it gave up. I moved it constantly 10 times with 2 second breaks after each 10x cycle of movement. And I moved the servo around 90 degrees each movement back and forth with some weight on the end of it.

The current drawn from the servo was around 4-6amp during those movements.

The gears are now locked at 5-10 degrees movement even with the motor removed entirely. The motor wires also burnt as you can see in the image and probably shorted destroying the motor? Im not sure.

I haven't tested the motor yet separately but the servo doesnt move at all so motor is probably damaged but unsure why the gears are stuck in this 5 degree angle. Is this common? I got the dsservo 25kg pro version.

UPDATE: one of the gears is stripped. Need to find a stronger servo possibly and reduce the voltage slighly or get brushless as they produce less heat I heard

I have tried many methods and aladhan api to calculate my masjids time and the algorithm they use behind to make their timetable but cannot figure it out. Im making a prayer times screen for all masjids. The use gives a timetable and then the software identifies the masjids method in calculating prayer times and display them on the screen.

Need help people

Just finishing up a project I’ve been meaning to do for a while. I was tired of the weak, pre-built extractors, so I decided to DIY one that actually pulls some air.

The heart of this thing is a 2A fan—too powerful. At full tilt, it’s probably a bit much, so I added an adjustable speed controller to keep the noise down when I don't need it at max.

Features:

Totally Portable: It runs on a 12V setup and soon adding a battery and a UPS module, so I can move it around my bench wirelessly.

Lighting: Tucked an LED strip in there to light up the board while I’m working.

Helping Hand: soon bolting on a crocodile arm to hold wires in place.

Organization: I designed a parts tray at the top to keep loose components from rolling away while I’m mid-solder.

Cost breakdown (Total was around £24- all parts from aliexpress):

Fan: £5.89

Battery: £7.30

UPS Module: £3.00

Crocodile Arm: £2.26

Speed Controller: £2.20

BMS: £1.00

Switch: £1.00

LED Strip: £0.33

Case: ~150g of filament

I designed it all on an ipad

Let me know what you think of it!

FYI : The project is still ongoing, going to add a pipe adaptor at the back for fume extraction. Battery is arriving soon, will simply wire it into its slot that has been made.
