MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 450KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor AX31-S1
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. 3C-2V/5C-2V coaxial cable.
Single bus.
Remote I/O net (remote I/O station).
MELSECNET/H network module capable of composing large scale flexible network system.
The MELSECNET/H network system includes the PLC network of the control station and the communication between the stations and the remote I/O network in the remote station remote I/O station.
Optical fiber loop system...... High speed communication of 10Mbps/25Mbps is realized.
The distance between stations, the length of the total cable length, strong anti-interference.
Coaxial bus system...... Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network.
Twisted pair bus system...... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.Motor series: low inertia, medium capacity.
Rated output power: 7.0kw.
Rated speed: 2000rpm.
With the brake: without.
Shaft end: straight shaft.
Brushless motor has small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, and stable torque.
Control is complex, easy to realize intelligent, and its electronic commutation method is flexible, can square wave commutation or sine wave commutation.
Motor maintenance free, high efficiency, low operating temperature, electromagnetic radiation is very small, long life, can be used for a variety of environments.
AC servo motor is brushless motor, which is divided into synchronous and asynchronous motor,
At present, the general use of synchronous motor control, which is a large range of power,
Can do a lot of power.
Large inertia, the maximum rotation speed is low, and with the increase of power and rapid reduction.
So it is suitable for the application of low speed and stable operation.
