Opening your Motor

In order to modify the insides of your motor, you first need to open it. Here's how.


Required materials:
Small flathead screwdriver or similar tool (for prying)


Step one: Pry the tabs up.
There are two metal tabs that hold the end bell (plastic end of the motor) down. Pry the tabs up carefully. A small flathead screwdriver is probably the easiest tool to use, but it's possible to do with other small, sharp tools. It's very easy to slip and stab a hole through your hand, so work carefully.

Step two: Remove the endbell.
On the bottom of the motor (opposite the wires), wedge your screwdriver/tool between the can (metal) and the endbell (plastic) and twist and pry to open up just a crack between the two parts of the motor. Now flip the motor over, and look for a crack going along the top of the endbell. Put the screwdriver into the crack and twist and pry to get the top side loose. Notice that a plastic part stays stuck to the can on top. Repeat for the bottom and top a few times, and even the edges if you think it is necessary. Hold the endbell by the sides, and the motor can, and pull them straight apart.

Step three: Move the brushes.
The brushes of the magnet are the parts coming from the left-over piece of plastic to the center of the motor. These are the most fragile part of the motor, and you must be careful not to (permanently) bend them or break them. Press against the top (outside) part of the plastic and bend the whole brush assembly up so that the brushes become parallel to the can. You actually will be bending the legs of the capacitors. DO NOT BEND THE BRUSHES.
