Claims

[Scope of utility model registration request]

In a servo device equipped with a plushless DC servo motor and a shaft encoder, a light source and a light receiving element are arranged facing each other across a shingle plate of the shaft encoder, and a phase switching signal is input to the light receiving element. A servo device comprising: a phase switching slit concentrically provided in the shielding plate; and a plushless DC servo motor that performs phase switching based on a phase switching signal from the light receiving element.
