For Any "Motor Expert"
 

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 .

This is a "universal" motor. It will run on AC or DC. This is
possible because it has a wound fiels - the polarity of both rotor and
field change together. A permanent magnet motor can NOT run on AC
because the field can't switch polarity - the motor just buzzes.

Universal motors have the brush angle a bit different than straight DC
motors to reduce brush sparking/burning - but they are fundamentally
the same.

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.

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")

To be more explicit: an AC induction motor runs at a speed determined
by the motor's winding geometry (which is fixed at time of manufacture)
and the frequency of the AC voltage applied. Varying the speed is done
either with mechanical gearboxes *or* a VFD (Variable Frequency Drive).

For small household appliances (drills, blenders, etc.) that desire some
sort of speed variation, an induction motor is impractical: the electronics
required to vary the frequency are more complex (than simply varying the
voltage)
