Brushless motor has small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, and stable torque.
Control is complex, easy to realize intelligent, and its electronic commutation method is flexible, can square wave commutation or sine wave commutation.
Motor maintenance free, high efficiency, low operating temperature, electromagnetic radiation is very small, long life, can be used for a variety of environments.
AC servo motor is brushless motor, which is divided into synchronous and asynchronous motor,
At present, the general use of synchronous motor control, which is a large range of power,
Can do a lot of power.
Large inertia, the maximum rotation speed is low, and with the increase of power and rapid reduction.
So it is suitable for the application of low speed and stable operation.

Shaft end: straight shaft.
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 HA-LF502
HA-LF502
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 HA-LF502. 5-100W small power control system. Drive: MR-H_ACN series built-in positioning function.
Rated output: 7.0KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop HA-LF502.
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,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encodder pulse, limiting the minimum detectable speed HA-LF502.
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 largger HA-LF502.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
