Therefore, AC servo motor and AC servo control system have become the basic techniques for accomplishing automation control technology in current industry field. For speed stability, brushless DC motor speed control systems offer a wide range of solutions. If required, torque motors or linear drive systems are used. A continuous rotation servo (sometimes referred to as a full rotation or just 360° servo) behaves more like a standard DC motor. In the AC drive, the motor’s back EMF (electro magnetic force) tends to be sinusoidal, while brushless DC servo motors have a trapezoidal back EMF. The most important amongst them are : AC servo motor, DC servo motor, brushless DC servo motor, positional rotation servo motor, continuous rotation servo motor, and linear servo motor. We first develop the differential equations and the Laplace domain transfer function model of the system DC motor/Load. After providing the terminology, symbols, and systems of units, this book goes on dealing with the basic theory, motor comparison, and basic speed control methods of motors. DC-motors are classi¯ed as armature controlled DC-motors and ¯eld controlled DC-motors [4]. Torque control system consist of speed control and current control, namely control system two level. . DC Servo Systems Ver.1 DC SERVO SYSTEMS. Se . The lack of feedback of a stepper motor limits its performance, as the stepper motor can only drive a load that is well within its capacity, otherwise missed steps under load may lead to positioning errors and the system may have to be restarted or recalibrated. . If you are planning on assembling your new robot, you will eventually want to learn about controlling variety of motors like DC motors, Stepper motors & servos. • Position Sensor: The position sensor is an incremental encoder with 1000 lines per revolution producing a resolution of 4000 counts/revolution. DC Motor Control Tips n Tricks (PDF 36p) This note explains many basic circuits and software building blocks commonly used to control motors. DC motor-encoder position servo controller 1. . Both computation engines are integrated into one monolithic chip. . Stepper motors are similar to Brushless DC motors in that the control system must commutate the motor through the entire rotation cycle. This is an automatic closed loop control… Instead of controlling the position of the servo, the controller sets the speed and direction of the motor. . For example, the control of a rotary inverted pendulum requires a DC motor to drive the arm and the pendulum as shown in Figure 2-1. . What is Servomechanism? Brush DC motor. 9.3 Mathematical model of DC servo motor . In order to be compatible with stepper logic controller accepts two inputs STEP and DIRECTION so an external trajectory controller can operate the motor as it would do with a stepper.
