Brushless motor as well as the pros and cons of actuator analysis
safe yuntai brushless motor as a gyroscope and even a bit high-end electro-optical pod actuator, accounts for more than 90% of the market.
here only analyze the nature of the brushless motor. strength: direct driving load. Didn't pass the slow, moped motor, without the influence of mechanical backlash. The precision of servo only depends on the closed-loop measurement precision of the gyroscope and encoder sampling precision. Brief: structure motor stator and rotor. Planning, device and its brief. : poor torque stiffness. Motor direct driving conditions, operation on top form, brushless motor, the motor input is actually the gyroscope angular velocity measurement. When the plane under the condition of little disturbance, disturbance angular velocity is very small, lead to motor torque is small. With the hand break around move feeling is at the origin of adjacent force is small. So the wind impedance can disturb will be poor. camera balancing requirements: brushless motor planning only used to overcome the friction bearing. The camera focus not on the motor axis will make a big probability of self-excitation problem.
