MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation MM-EFS15K1M MM-EFS15K1M MM-EFS15K1M MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 2.2KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions MM-EFS15K1M.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder.
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc.) and torque control. Power: 15kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose MM-EFS15K1M. ) Superior high efficiency IPM motor.
Output power: 30kw.
Rated speed: 1500r/min.
Voltage level: 200V.
IPM motor MM-EFS series can not be used to run the poower frequency power MM-EFS15K1M.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time.
