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 .
A series motor has infinite torque at zero RPM and zero torque at
infinite RPM - there is no "running soeed" - it will keep gaining
speed with no load untill it blows up.
A shunt wound motor has a running speed where the supply voltage and
the CEMF balance out - the motor will draw current as required to
maintain that speed under any load - and if not externally limited it
will burn itself out trying to maintain that speed.
