ABSTRACT

The provided is a rotational speed detection structure of an actuator and an
actuator. The rotational speed detection structure of an actuator includes an
outer housing, a motor, and a reducer mechanism, where the motor includes a
stator and a rotor; a shaft sleeve is connected to the rotor; the reducer
mechanism includes an input end connected to the rotor, and an output end
connected to an encoder shaft; a first mounting surface is disposed on the
encoder shaft; a second mounting surface is disposed on the shaft sleeve; a
first magnetic ring is fixed on the first mounting surface; a second magnetic
ring is fixed on the second mounting surface; a printed circuit board (PCB) is
fixed on the outer housing; the PCB includes a third mounting surface; a first
Hall element and a second Hall element are provided on the third mounting
surface.
