nonsense it is clearly an induction motor.

According to my Electrical Engineering professor at university *all*
electrical machines (including transoformers) are really induction
motors.

Motors with squirrel-cage rotors can be used on single-phase alternating
current by means of various arrangements of inductance and capacitance that
alter the characteristics of the single-phase voltage and make it resemble a
two-phase voltage. Such motors are called split-phase motors or condenser
motors (or capacitor motors), depending on the arrangement used.
Single-phase squirrel-cage motors do not have a large starting torque, and
for applications where such torque is required, repulsion-induction motors
are used. A repulsion-induction motor may be of the split-phase or condenser
type, but has a manual or automatic switch that allows current to flow
between brushes on the commutator when the motor is starting, and
short-circuits all commutator segments after the motor reaches a critical
speed. Repulsion-induction motors are so named because their starting torque
depends on the repulsion between the rotor and the stator, and their torque
while running depends on induction. Series-wound motors with commutators,
which will operate on direct or alternating current, are called universal
motors. They are usually made only in small sizes and are commonly used in
household appliances.
