MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.4KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation A616AD To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitted A616AD.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve A616AD. Servo motor series: ultra low inertia, small capacity.
Rated output: 0.1kw.
Rated speed: 3000r/min.
Electromagnetic brake: incidental.
Power supply: 200V.
The rated speed is 3000r/min, the maximum speed is 6000r/min.
The maximum torque of 350% of the rated torque, high torque in the field of high rotation, only to support the HG-KR series products.
Built in absolute position encoder with high resolution.
Standard high resolution absolute position encoder (4194304p/rev (22bit)).
To achieve a higher accuracy of the positioning function.
Improve the environmental performance of HG-KR, HG-MR, HG-RR, HG-UR series of products using IP65. Power: 0.4kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option iis installed in the FRR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity MITSUBISHI A616AD.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motorr ppower used to select the DC reactor MITSUBISHI A616AD.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
