DC Servo Motors
A DC servo motor consists of a small DC motor, feedback potentiometer, gearbox, motor drive electronic circuit and electronic feedback control loop. It is more or less similar to the normal DC motor.

The stator of the motor consists of a cylindrical frame and the magnet is attached to the inside of the frame.

The rotor consists of brush and shaft. A commutator and a rotor metal supporting frame are attached to the outside of the shaft and the armature winding is coiled in the rotor metal supporting frame.

A brush is built with an armature coil that supplies the current to the commutator. At the back of the shaft, a detector is built into the rotor in order to detect the rotation speed.

With this construction, it is simple to design a controller using simple circuitry because the torque is proportional to the amount of current flow through the armature.

And also the instantaneous polarity of the control voltage decides the direction of torque developed by the motor. Types of DC servo motors include series motors, shunt control motor, split series motor, and permanent magnet shunt motor.

1.The power supply voltage varies the characteristics of the repetitive use area.
The solid line shows three phase 200 V single phase 230 V input, the broken line is single phase 200V input, and the single dot chain line shows the characteristic when the single phase 100V is input.
However, the sgma-a5a type has the same characteristics in three phases 200 V and single phase 200V.


2.If the effective torque is within rated torque, it can be used within the repeated use area.



3.Note that the voltage drop increases and the repetitive use area is narrow for the servo motor main circuit cable over 20 meters.
