Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectable speed.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.

Comparison of single phase induction motor and servo motor.
The working principle of the AC servo motor is similar to that of the single phase induction motor,
But the rotor resistance of the former is much larger than that of the latter,
So the servo motor is compared with the single machine asynchronous motor,
There are three notable features:
1, large starting torque MR-H700ACN.
2, a wide range of operation.
3, no rotation phenomenon.
AC servo motor running smoothly, low noise.
But the control characteristic is non-linear, and because the rotor resistance is big, the loss is big, the efficiency is low,
Therefore, compared with the same capacity DC servo motor, the volume is large and the weight is heavy,
So it is only suitable for 0.5-100W small power control system. 1 axis servo amplifier.
