A composite motor having high-precision positioning, comprising: a housing (), a rough positioning assembly, a hollow output shaft (), a fine positioning assembly, a power switching apparatus and a controller (). A stepper motor () in the rough positioning assembly is responsible for rough positioning of the composite motor, an annular travelling wave ultrasonic motor in the fine positioning assembly is responsible for tail end fine positioning of the composite motor, and the controller () implements power output switching between the annular travelling wave ultrasonic motor and the stepper motor (). The composite motor effectively solves the problem that annular travelling wave ultrasonic motors which operate continuously for a long time have a short service life, and ensures high-precision positioning while also extending motor service life.
