Hello,

Not a motor expert, but just very curious, and would like to learn.

Have a home food blender. Works on regular wall outlet.

Motor has armature windings.
Also has field (stator) windings.

Also has a commutator.

What kind of a motor is this ?

Advantages of a motor like this compared to perhaps a regular ac
induction motor ?

Have never seen a commutator on an ac motor before.
Is there a rectifier hidden somewhere ?

Thanks,
Bob

Most good quality mixers will have a brush motor...for their size
they have more power. Large commercial units mostly have capacitor
start or DC motors.

You didn't answer any of the OP's questions.

Maybe someone who actually knows the answers will come along.

It's called a universal motor , and it will run on either AC or DC . There
are 2 flavors of universal motor , series wired or shunt wired . I don't
remember why each is more desirable for certain tasks .

It's almost definitely series wound. They're good for high speed *and* being
able to vary speed by varying the applied voltage (e.g., with something
akin to a "dimmer circuit")
