Spike prime large motor disassemble

Recommended Posts

I get spike motor and want to know how to work it.

1.jpg

It's nealy impossable to disassemble without breaking. Even shaft is strangly locked to upper parts.

Back part(dark azure), number 39546

Motor, circuit board, wire and wire clip(don't have part number here)

2 stage planetary gear reduction(I don't count gear tooth)

Some massive bevel gear

Magnet encoder shaft and upper parts, number 39544(can't disassemble more so can't fine shaft part number)

Lower part, number 41775

Lower part

3.jpg

Upper part and shaft, bevel gear, stage 1 planetary gear

Black part of shaft is magnet

4.jpg

Stage 2 plenetary gear and encoder circuit board

5.jpg

Inside of under part

6.jpg

Motor assembled with planetary gear and other basic thing

Motor is same size with PF/C+ L motor, train motor's internal motor. Bigger than 130 used in M motor. according to motor size, I think spike medium motor use 130 like M motor.

Inserting massive bevel gear for shaft

8.jpg

Bevel gear and shaft connect like this.

9.jpg

connect shaft part to base motor part.

But according to strange connection of under part, You nees motor part put in to under part first. If add upper or lower part like this picture, you can't put under part.

 

 

If you have any question, say to me.

Can you make and post very good pictures of the circuitboards?
So we can see chip numbers, wire connections etc.
This to figure out how they ID this motor and control it.

Having an encoder in a LEGO motor is going to be a gamer changer for the GBC guys

Not if you want to keep everything mechanical (like me). Also, can't be connected to 9V train power supply with standard wiring so it will be eating away batteries like crazy on an event day.

Thanks @msk6003!

To be sure I make no mistake... is this OK (edited photo below)?

No number on cable retainer?

Azure shaft can't be disassembled, but on your image 3.jpg I faintly see something on the side of shaft that could be the part number, can you have a look?

This shows the current limiting device of the motor. Holds unlimited time at 0.5A, trips above 1A.

Can't find any number on cable retainer also don't have number on side of shaft.

Maybe or maybe not.  We've already been using Mindstorm for ages.  Its motors have encoders.

I was gonna say.

Plus: The LEGO rotation sensor did and does a reasonable good job as encoder on RCX PBricks. Used it before for PID controlled trains (https://www.eurobricks.com/forum/index.php?/forums/topic/45440-lego-train-control-using-rcx10-pbricks/)

The integrated encoder is much more elegant of course. So when @dr_spock refers to "Mindstorms", any "dumb motor + RCX rotation sensor" as well as the NXT and EV3 motors did/do that.

And what's the origin of the horrible buzz sound, especially when the motor is on a flat surface… All my four motors have this problem…

This is the result of the 1kHz frequency of PWM (pulse width modulation) used to regulate speed of motors.
