MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 0.1kw.
Interface type: CC-Link communication type (built-in positioning function).
Power specification: single phase AC200V.
Positioning operation by setting position and rotational speed data in the positioning table and receiving the start signal from the main controller.
The setting of the position and speed of the positioning table, as well as the start and stop operation can be completed through CC-Link communication.
By using the MR-J3-D01 extension IO unit, the DI/O instruction can be used to select and locate the table.
(CC-Link can not be used for MR-J3-D01 communications).
With built-in positioning function of the servo amplifier, can be set through the CC-Link communications and speed data. (corresponding to the CC-Link version: Ver.1.10)
Can be achieved through the CC-Link communications to start, stop and monitoring and other operations.
Serial communication reduce wiring.
Distributed servo control system can be built by CC-Link communication.
The parameters of unit MR-PRU03 (optional) the parameter setting, operation and monitoring more convenient.
The servo amplifier can be used for speed control operation.
When the two stations are occupied, the speed can be set directly by the remote register.
Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 1.0kw.
Rated speed: 3000rpm.
With a brake band.
Shaft end: straight shaft.
When the AC servo motor has no control voltage, only the pulsating magnetic field generated by the excitation winding is generated in the stator, and the rotor is still not moving MR-J3-10T.
When the control voltage is controlled, a rotating magnetic field is generated in the stator, and the rotor rotates in the direction of the rotating magnetic field,
In the case of constant load, the speed of the motor varies with the size of the control voltage,
When the phase of the control voltage is reversed, the servo motor will reverse MR-J3-10T
MR-J3-10T Type: HC-PQ type.
Output power: 0.03kw.
Rated speed: 3000r/min.
Electromagnetic brake: there.
Key axis: D type 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 performance MR-J3-10T.
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 without 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. 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 wiide range of operation MR-J3-10T.
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-J3-10T. 5-100W small power control system.
