Servo motors are widely used in the field of motion control in factory automation. The control target can be position, speed, or force, among others. These motors come in both AC and DC power supply units. AC servomotors are permanent magnet synchronous motors and have low torque-to-inertia ratios f or high acceleration ratings. They have an output shaft that can be positioned by sending a coded signal to the motor. They are generally small and powerful in their size, and easy to control. The most common form of AC servomotor includes induction and gearmotor types. A DC serve motor has an output shaft that can be positioned by sending a coded signal to the motor. The common type of DC motors include brushless or gearmotor type. Static eliminator is used to eliminate static and dust and can neutralize and clean surfaces at remote distances. Shockless eliminators limit the current at the points to a very low level. Hot static eliminators offer greater efficiency in certain restrictive applications including extremely high charges or dirty environment. A wide range of static eliminators is manufactured by a host of manufacturers.
