2204 gimbal motor nondestructive rotor stopper removal

FOC automatic rewind soldering iron stand

The motor used is a 2204 gimbal motor 330KV

Nondestructive disassembly method

In addition to printed parts, you also need to prepare

M2*6 screws (for fixing the motor)

M3*20 countersunk screws (can automatically center)

5mm diameter aluminum rod, recommended length 25mm or 28mm or 30mm

Vise, or hammer

Grind one end of the aluminum rod with a hand drill and sandpaper to a diameter less than 5mm, 4.9mm is recommended, as shown in the figure

First remove the motor's magnet and take off the circlip and copper washer

Then fix the motor with M2 screws

After the M3 screw passes through the rotor and motor, screw on the aluminum rod, the ground end, aligning it with the motor shaft when screwing

Then it can be placed on the washer (printed cylindrical tube) and pushed out

This method can achieve nondestructive rotor removal

The pushing process will not damage the tail end of the motor shaft, preventing deformation that could cause it to pop out or not be able to press it back in after pushing it out

Because the aluminum alloy stud material is softer than the motor shaft

If a puller-type tool that uses an M5 screw to push it out is used, there is a chance of burring or deforming the tail end of the motor shaft

If you have a vise, it's very easy to push, because a vise can apply pressure more vertically, and it's convenient to put it back after removing the stopper

If you use a hammer to tap, you need to use light force multiple times, don't expect miracles with heavy force
