servo motorServo motor, also known as actuator motor, is used as an actuator in automatic control systems to convert received electrical signals into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no self rotation phenomenon, and the speed decreases uniformly with the increase of torque.Servo motors mainly rely on pulses for positioning. Basically, it can be understood as follows: when a servo motor receives one pulse, it will rotate the corresponding angle of one pulse to achieve displacement. Because servo motors themselves have the function of emitting pulses, every time they rotate an angle, they will emit a corresponding number of pulses. This forms a response or closed loop with the pulses received by the servo motor. In this way, the system will know how many pulses have been sent to the servo motor and how many pulses have been received back. In this way, the rotation of the motor can be accurately controlled to achieve precise positioning, which can reach 0.001mm.DC servo motors are divided into brushed and brushless motors. Brushed motors have low cost, simple structure, large starting torque, wide speed range, easy control, and require maintenance. However, maintenance is inconvenient (such as replacing carbon brushes) and can generate electromagnetic interference, which has environmental requirements. Therefore, it can be used in cost sensitive general industrial and civilian applications.
