Popular science about servo motors
Servo motor refers to the engine that controls the operation of mechanical components in the servo system,and is an auxiliary motor indirect speed change device, is widely used in automatic control. It can control the speed, and the position accuracy is very accurate, can convert the voltage signal into torque and speed to drive the control object.The rotor speed is controlled by the input signal and can react quickly. In the automatic control system, it is used as an actuator, controlled by the servo controller; and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into an angular displacement or angular velocity output on the motor shaft. Its main feature is that there is no rotation when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque.
Servo motor is usually equipped with high-precision standard encoder to send pulse control signals, and can also be equipped with a gearbox, so that the mechanical equipment can bring reliable accuracy and high torque. It has good speed regulation performance, large output power. The torque fluctuation of the multi-stage structure is small.
It can be divided into two categories of DC and AC servo motors.The DC servo motor is divided into brushed and brushless motors. The AC servo motor is also brushless motor, divided into synchronous motors,induction motors, permanent magnet AC servo motors. DC servo is controlled by trapezoidal waves while AC servo by sine waves with small torque pulse.
