Title:
ROTARY ACTUATOR INTEGRATED WITH GEAR NONIUS ENCODER, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/060987
Kind Code:
A1
Abstract:
The present invention discloses a rotary actuator integrated with a gear nonius encoder and a control method, which relates to the field of aircraft devices. The rotary actuator comprises a permanent magnet synchronous motor, a gear nonius encoder, a gearbox, a rudder arm and a control circuit module. The control circuit module comprises a circuit board. The gear nonius encoder comprises a main gear, a main gear magnet steel, a main gear magnet encoding chip, a nonius gear encoding chip, a nonius gear magnet steel and a nonius gear. The main gear is mounted at the bottom of a rotor shaft of the permanent magnet synchronous motor. The main gear is rotatably connected to the nonius gear through meshing. The main gear magnet steel is mounted on a surface of the main gear away from the rotor shaft. The nonius gear magnet steel is mounted at the bottom of the nonius gear. The main gear encoding chip is arranged between the main gear magnet steel and the circuit board. The nonius gear encoding chip is arranged between the nonius gear magnet steel and the circuit board. The rudder arm is rotatably connected to the top of the gearbox. The bottom of the gear box is connected to the permanent magnet synchronous motor through the top of the rotor shaft of the permanent magnet synchronous motor.
