Drive: MR-H_ACN series CC-LINK features.
Rated output: 22KW.
The test system is composed of two parts, namely, the servo driver, the motor system and the host computer.
Servo drives start to run in accordance with the instructions.
In the course of operation, the running data of the servo system is collected by the host computer and the data acquisition circuit,
And carries on the preservation, the analysis and the display to the data. Because the motor is not loaded in this test system,
So compared with the previous two kinds of testing systems, the system has a relatively small volume,
But it also makes the system can not simulate the actual operation of the servo drive.
Usually, such testing system is only used to test the rotational speed and angular displacement of the tested system under no-load condition,
And can not carry on the comprehensive and accurate test to the servo drive.

Function of switching amplitude. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth. Motor series: ultra low inertia, small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.2kw.
Rated speed: 3000rpm.
With the brake with brake.
Without GB.
Shaft end: straight shaft.
The rotor of the servo motor is a permanent magnet, and the control of the servo amplifier is controlled by the U/V/W three-phase electric electromagnetic field,
The rotor rotates under the action of the magnetic field, and the encoder feedback signal of the motor is given to the driver,
According to the feedback value and the target value, the driver is compared,
Adjust the rotor rotation angle.
The accuracy of the servo motor is determined by the resolution of the encoder. Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.1kw.
Rated speed: 3000rpm.
With the brake: without.
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 wiide range of operation MR-H22KTN.
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, comparred with the same capacity DC servo motor, the volume is large and the weight is heavy,
So it is only suitable for 0 MR-H22KTN. 5-100W small power control system.
