MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 2.0kw.
SSCNET interface.
Voltage: 3 phase AC400V.
The communication cycle between the controller and the servo amplifier is the longest 0.888ms.
Such systems will be able to provide high reliability and high performance.
In the motion system, the parameters of the servo amplifier and the acquisition of the data will be displayed on the motion controller.
Connect a dedicated cable with an amplifier and a controller to form a SSCNET system.
This simple connection method reduces the routing time and helps to prevent noise.
Even in the MELSERVO-J2-SUPER series products using high resolution coding standards, the command frequency is no limit.
It is only necessary to add a battery on the servo amplifier, which can form the absolute value system.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use.
Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.2kw.
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 MR-J2S-200B4
MR-J2S-200B4
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 MR-J2S-200B4. 5-100W small power control system. Motor: HA-LH type.
Power: 22kw.
Speed: 2000r/min.
According to the types of power supply: can be divided into DC motor and AC motor MR-J2S-200B4.
The structure and working principle of DC motor can be divided into four parts: brushless DC motor and brushless DC motor.
Brushless DC motor can be divided into: permanent magnet DC motor and DC motor.
DC Motor Division: Series DC motor, DC motor, DC motor and DC motor.
Permanent magnet DC Motor Division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum nickel Gu Yongci DC motor. Type: HC-PQ type.
Output power: 0.1kw.
Rated speed: 3000r/min.
Electromagnetic brake: there.
Key axis: straight shaft.
Motor aspects: the material, structure and processing technology of the servo motor is much higher than that of AC motor,
That is when the driver output current, voltage, frequency change is fast power supply,
The servo motor can change according to the change of the response of the power supply,
Response characteristics and anti overload capacity is much higher than the AC motor drive,
Motor aspects of the serious differences between the two are fundamentally different perfoormance MR-J2S-200B4.
That is not the inverter output can not change so fast power signal,
But the motor itself can not react,
So in the frequency of the internal algorithm set to protect the motor to do the corresponding overload.
Of course, even wwithout the ability to set the output of the inverter is limited,
Some of the excellent performance of the inverter can be directly driven servo motor MR-J2S-200B4.
