The size and shape of the servo motors are dependent on the application. 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. A servomotor is a specific type of motor that is combined with a rotary encoder or a potentiometer to form a servomechanism. A servo motor usually comes with a gear arrangement that allows us to get a very high torque servo motor in small and lightweight packages. These motor + linear encoder systems avoid inaccuracies in the drivetrain between the motor and linear carriage, but their design is made more complicated as they are no longer a pre-packaged factory-made system. But some motor types are better suited for servo applications — which often involve high-precision moves with well-regulated speed or torque — than others. The output shaft of the servo is capable of traveling somewhere around 180 degre… The servo motor is controlled by a signal (data) better known as a pulse-width modulator (PWM). Servo motors being manufactured by many companies some of them are FUTABA, HITECH, AIRTRONICS, and JR RADIOS. Servo motors can be of different types on the basis of their applications. Servo motors can be classified based on three factors: DC vs. AC. Types of Servo Motor These motors are classified into different types based on their application like Brushless DC, AC, continuous rotation, linear and positional rotation, etc. Airtronics style) Figure 4 shows the different styles and maps the wire’s color to its function. Contact Us. A noisy or chattering servo axis is perhaps the single most common motion problem that engineers encounter when building their DC Brush or Brushless DC motor-based machine. They are DC motors whose speed is slowly lowered by the gears. If motor is powered by a DC power supply then it is called DC servo motor, and if it is AC-powered motor then it is called AC servo motor. Positional Rotation Servo— This variety rotates within a 180° range. The servo-motors are of the following two types: D.C. servo-motors. Tuning Free Servo Motor products or Hybrid Servo Motor / Stepper Motor products. This motor is used to start, move and also stop the conveyor belts carrying the product along with many stages. Servo motors are popular for a number of reasons, including their power efficiency and small size.
