HG-JR703 High capacity servo motor in low inertia

Type: HC-PQ type.
Output power: 0.2kw.
Rated speed: 3000r/min.
Electromagnetic brake: there.
Key axis: L 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 HG-JR703 HG-JR703
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 HG-JR703.
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: 0 HG-JR703. 4kw.
Rated speed: 3000rpm.
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. Drive unit.
MITSUBISHI universal AC servo amplifier MELSERVO-J4 series.
Rated output: 30kw.
Interface: universal type.
Power supply: three phase AC400V.
Support position control, speed control, torque control.
Position control to follow the position instructionns HG-JR703.
When the control is inserted, the position control is performed.
Speed control follows the speed command to control the speed within a certain range.
Torque control to follow the torque command to control the stable torque.
Function of switching amplitude HG-JR703. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth.
