MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible MITSUBISHI FR-PU07 FR-PU07
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced MITSUBISHI FR-PU07.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.1KW.
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 MITSUBIISHI FR-PU07 FR-PU07 MITSUBISHI FR-PU07 MITSUBISHI FR-PU07. Superior high efficiency IPM motor.
Output power: 3.7kw.
Rated speed: 1500r/min FR-PU07 MITSUBISHI.
Voltage level: 400V.
IPM motor MM-EFS series can not be used to run the poower frequency power MITSUBISHI FR-PU07.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time.
