Stabilizer for a Photographing Apparatus and a Control Method for Such a Stabilizer

摘要

A stabilizer for a photographing apparatus is disclosed. The stabilizer includes a first rotating shaft driven by a first three-phase brushless AC motor, a second rotating shaft driven by a second three-phase brushless AC motor, a first magnetic rotary encoder mounted on the first three-phase brushless AC motor, a second magnetic rotary encoder mounted on the second three-phase brushless AC motor, an inertial sensor, a fixing member, and a controller. The first and second three-phase brushless AC motors, the inertial sensor, and the first and second magnetic rotary encoders are electrically connected to the controller, respectively. The inertial sensor is mounted on the fixing member, the center axes of the first and second rotating shafts are perpendicular to each other, the fixing member is connected to the first rotating shaft, and the first three-phase brushless AC motor is connected to the second rotating shaft by a bending member.
