Proportional adjustment electric control actuator

The invention provides a proportion adjustment electric control actuator which comprises a motor (1), a signal gear piece (6), a first Hall sensor (12), a second Hall sensor (13) and a magnetic ring (15); a permanent magnet (7) is fixedly installed on the signal gear piece (6), and the magnetic ring (15) forms at least one set of N and S through radial magnetization; an output shaft of the motor (1) is fixedly connected with the magnetic ring (15), the first Hall sensor (12) and the second Hall sensor (13) are arranged below the magnetic ring (15) and the signal gear piece (6) respectively, the first Hall sensor (12) collects N and S switching signals when the magnetic ring (15) rotates, and the second Hall sensor (13) collects position signals of the permanent magnet (7). By using the electric control actuator, non-contact high-precision position detection can be achieved, the service life of the proportional adjustment control electric actuator can be prolonged, and the control electric actuator has the out
