Blender Parts

Level of Difficulty: Moderate

Duration: 1 hour

I just happen to have an assortment of junk blenders in my possession that either have burnt out motors or have worn out brushes. 

Instead of discarding of them immediately, I decided to store them in the hopes of one day, re-purposing them. Now, I've decided to scrap them of their usefulness and then discard of the remnants.

In this tutorial, I will be dismantling 5 blender models to show you the different components that can be saved.


Tools

All I used were:

  • a flat nose pliers
  • a cutting pliers
  • a Phillips screwdriver
  • a Flathead screwdriver
  • a ratchet and socket set (depending on model) 

Material

These are the electric blenders I will be dismantling. They are all 350W models and I will be showing how I took apart each model in its own section. Perhaps the most useful components that can be salvaged from this pile of junk are the switches, the insulated copper wires and maybe the power cords.


Model A: Hamilton Beach 7 SPEED BLENDMASTER

This particular blender has a seized motor shaft and a broken bowl. 

The two halves of the housing is fastened together by two screws on the bottom of the blender and a tab located near the power cord.

I used the Phillips screwdriver to remove the screws. 

On the right is the case opened. The electric motor is encased in plastic shown in black.

Use the cutting pliers to cut the power cord from the motor and switch. It goes without saying that the appliance should not be plugged in to prevent electric shock. This model has two screws holding the motor in place. Remove them.

The switch just comes out without any fasteners holding it in place. As for the drive socket (the black mushroom shaped plastic on the right), I found it a bit difficult to remove due to the corrosion, so I got a little creative.

First I tired prying it off with a flat head screwdriver then ... 

With the flat nose pliers, but it proved to be a bit stubborn so I broke out the motor instead. 

Onto the next step.

Now cut away the wires from the switch to the motor at the motor end. This prevents the wires from being ruined. The motor plastic housing has four screws holding it together.

Remove them.

Inside you will find the fan, rotor and the stator. Also, the brushes will be visible in both the plastic haves.

Remove the brushes. These may be reused in a similar motor with worn brushes. Remove the rotor and the stator.

The rotor is wrapped with hundreds of feet of fine gauge insulated copper wire. It's a bit difficult to remove in perfect condition and is probably not worth it. What is worth the time and effort though is the much thicker copper wires on the stators. 

It is much more manageable and is more useful, such as using it to build a custom transformer of even an electromagnet.

Begin by cutting the wires from the terminal block. Next, unwind the wire loops one at a time unto a reel or pencil. I used an empty tread reel. 

I got four separate wires from the stator coils, shown wound on the reel above. It's up to your imagination what to do with the rotor.

On the left are the salvaged items including the multi button push switch, a power cord, a couple of screws, a pair of carbon brushes, a metal fan, two bearings, and last but not least, the insulated copper wires.

On the right are the discarded items including the blender housing and the corroded metal parts. 

On the next page, the remaining blenders will be dismantled and the parts placed in the respective boxes.

Please note that the other blenders are different and therefore handled differently.
