HIV (human immunodeficiency virus) is a virus that attacks the immune system, the body's natural defense system. Without a strong immune system, the body has trouble fighting off disease.
Servo-Tek Distributor: DC Tachometer Generators. A Servo-Tek DC tachometer generator provides a convenient and economical means of converting rotational speed into an isolated analog voltage signal suitable for remote indication and control. Combining high accuracy with low driving torque, Servo-Tek tach generators are ideal for use in servo systems. Tach Generators are particularly suited to application in precision integrators and velocity servos, both of which require a highly linear speed/voltage relationships with minimum ripple.
Robot Actuators-Different Types. An actuator is a mechanism for activating process control equipment by the use of pneumatic, hydraulic, or electronic signals.There are several types of actuators in robotic arms.Synchronous Actuator-The motor contains a rotor that rotates in synchrony with the oscillating field or current.1  Brushless DC Servo-This synchronous electric motor features permanent magnet poles on the rotor, which are attracted to the rotating poles of the opposite magnetic polarity in the stator creating torque.ynchronous Actuator-The motor contains a rotor that rotates in synchrony with the oscillating field or current. 1  Brushless DC Servo-This synchronous electric motor features permanent magnet poles on the rotor, which are attracted to the rotating poles of the opposite magnetic polarity in the stator creating torque.
