Mini Sensorless Vector Frequency Inverter
Voltage and power range：
3phase, 380v : 0.4~5.5 kw
3/1 phase, 220v: 0.4~3.7kw
Output frequency range: 0.00Hz-400.00 Hz
SVF-MN series frequencyinverter could be widely used in the industry of food, packing, textile,engraving machines, washing machine, offset machine and rolling door etc.
(1) Open-loop vector control: Steady speed with highprecision, wide range of speed governing, as the speed ratio is 1:150 and frequencyis 0.5Hz, we could output 150% rated torque. Good dynamic performance.
(2) VF control: Multipoint VF curve. This apply to the situation that one frequencyinverter drives multiple motors, such as fan, water pump, engraving machine,injection molding machine etc.
1.Adopts 16 bit microprocessor, sine wave PWM control
2.Automatic torque ascension and automatic sliding compensation function
3.Output frequency 0.1-400 Hz
4.8 period of speed setting and 7 period can be running the program
5.Low noise, carrier frequency can from 1 kHz-15 kHz adjustment
6.Two paragraphs Acceleration and deceleration time and two segments of the S Curve slow and deceleration
7.Simulation frequency set acceptable 0-10 VDC, 4-20 mA
8.The built-in serial communication interface RS-485(baud rate can reach 38400)
9.Save energy running and automatic voltage stabilizing section function (AVR)
1.Adjustable V/F curve Acceleration and automatic and deceleration function
11.Simple vector control and built-in PID control, and the simple positioning function
12,Sleep/wake up function and zero velocity keep function
- Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
- Power will drop, down to the original one-tenth
- Q:Fuji inverter motor set the number of poles will not have any effect?
- The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
- Q:Is the speed of the motor controlled?
- Armature for the cast steel made of cylindrical structure, which is connected with the squirrel cage induction motor shaft, commonly known as active part;
Pole made of claw-shaped structure, mounted on the load shaft, commonly known as the moving part.
The active and slave parts are mechanically free of any contact.
- Q:The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
- Motor speed formula:
N = 60f / p
In the above formula
N - the speed of the motor (r / min);
60 - per minute (s);
F - power frequency (hz);
P - pole pairs of motor rotating magnetic fields.
- Q:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
- 2 pump power: If there is a tank, optional small pump, or should see how many households, fixed flow.
- Q:Acer laptop power adapter
- the price is not very clear. You can go online to see the price such as Taobao
- Q:Lenovo g450 laptop power adapter specifications is what?

- Q:How to choose a Siemens inverter for a 5.5KW three-phase motor (2 pole)?
- Beijing easy to create a website with Siemens inverter selection manual! You can log on online! Or contact them directly, they will give you professional answers!
- Q:Why the number of motor poles increased, the inverter capacity will increase
- The number of poles of the motor is not directly related to the rated current, but the number of poles is larger and the power factor is lower and the rated current will be higher.
- Q:The laptop power adapter is burned
- If the power adapter is burned, you should check the laptop's power outlet, if the socket short circuit will lead to the power adapter burned.
Maintenance method is not a power adapter and only use the battery boot try, can not boot, then the laptop itself is a problem, to send maintenance department maintenance; if you can boot, you can confirm that the power outlet is short, can be opened Laptop case, swap a new power outlet to solve the problem.
