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.
Servo controllers are a wide category of motor control. 1  Common features are: 2  precise closed loop position control. 3  fast acceleration rates. 4  precise speed control Servo motors may be made from several motor types, the most common being: brushed DC motor. brushless DC motors. AC servo motors.
