I got a new Ninja blender (model ss351) a few months back that was DOA. The manufacturer sent a replacement immediately, but I found a blog post on hackaday showing a simple mechanical mod that would enable me to use the motor to drive a flexible rotary tool shaft (Dremel etc). The attached images are the motor, the control board and the power board. The purple wire to the control board is directly from the wall outlet.

Simple questions;

How can I test the motor itself to make sure it wasn't the specific component that failed? Will simply driving it from a bench psu do it? What minimun V/I?

Is this motor viable for this application? Optimally, I'd like continuous speed/torque control with a foot pedal. I'm not scared of building a circuit from scratch (_yet_).

If not viable, can I use it for a pedal powered generator?

I can link to the hackaday post and the rotary tool shaft if necessary. Also, obviously please let me know if additional pictures are needed.

Thanks so much in advance

It looks like a universal motor, so it's just direct connection to the mains, better pictures of the motor would be great, .

 

Agree, if it has brushes, it is a Universal motor, if you power it up direct to the mains, unloaded, just test it briefly as it will wind up pretty good!

Better in what way? Should I look for a label or something?

Brushes!

I should be able to lift the top cover of the motor in an hour or so. But I am seeing quite a few brushless control tutorials with Arduino from Google, so not scared yet.

 

If it has Brushes, (Universal motor) It is often controlled by Triac etc.

Crap, either that top screw is frozen or they used some adhesive. Regardless, I don't really feel like disassembling it any further,. Here are w more pics. The one with my thumb in it is really distorted though. That top plastic circular piece is at least 4 times as big as my thumb and that cylindrical plastic piece right below the ziptie is about half the size of my thumb.

Should I just call the manufacturer tomorrow?

Thanks again

I still think it is a Universal type, what is the part number of the device mounted on the heat sink in the third pic in the OP?

*Damn that wheeler gunsmith bench magnifier is boss

It's also got a logo like an M with musical note "feet", I don't know if I can take a picture

Suspected as much, it is a Triac, which also points to it being a Universal motor.

Triac 600V 16A, Motorola or ST micro, .
