MITSUBISHI FX-20DU-E Market price | FX-20DU-E Introduction

Drive: MR-H_ACN series built-in positioning function.
Rated output: 22KW.
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.
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 FX-20DU-E
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 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. Servo motor series: low inertia, medium and large capacity.
Rated output: 0.75kw.
Rated speed; 3000r/min.
Electromagnetic brake: No.
Power supply: 400V.
Most suitable for medium and large capacity, low inertia type products in high frequency operation or acceleration and deceleration operation.
Improve the environmental performance of HG-SR, HG-JR series of products using IP67.
High speed & high torque. Shorten the positioning time, achieve high-speed equipment.
100 scene, there are 100 different drive control.
In order to meet the needs of the diverse and detailed field,
MR-J4 product line configuration, providing a wealth of servo amplifier and servo motor products.
Can meet the different needs of different customers. Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 1.5kw.
Rated speed: 2000rpm.
With a brake band.
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.
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.
