MITSUBISHI MR-J3-500BS Market price | MR-J3-500BS Introduction

MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 15KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) MR-J3-500BS
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load. Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.2kw.
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 AC200V.
Special specifications: full closed control 4 wire / support mechanical end encoder ABZ phase input / support positioning mode.
Support position control, speed control, torque control.
Position control to follow the position instructions.
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. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth.
