- Q: What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
- Electronic governor is for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the power supply power for the output does not change, so this speed is not an energy Type of speed control methods, such as home for the use of fans and the like. Inverter speed is the original direct input three-phase asynchronous motor power first access to the inverter, in the inverter through the PWM and other electronic converter technology to rectify the frequency AC, inverter, become a frequency controllable AC In the input to the motor, in the motor running through the V / F control, output torque control, vector control and other control methods to adjust the frequency, change the loop current, to achieve energy-saving operation, especially in the light load energy efficiency is obvious, An energy-saving products that have been widely promoted and applied
- Q: Three-phase asynchronous AC motor speed control method
- Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch to full speed operation, to avoid shutdown; Thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders.
- Q: What is the laptop power adapter? Is it the battery?
- Notebook power adapter, of course, is not referring to the laptop battery.
- Q: Can the laptop 1.3a power adapter be used on a 1.5a device?
- No, use a power adapter that is equal to or slightly larger than 1.5a.
- Q: Three-phase two-pole motor can be used to reduce the frequency of the inverter
- Speed range adjustable, you can drop to any speed you want!
- Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
- 4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear. 5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place. 6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water. 7, single-phase motor: When the scene using single-phase motor, the inverter useless. 8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter
- Q: B2b frequency how to speed
- How does changing the power frequency to change the speed of the motor? When the motor is connected to the power supply to drive the normal operation of the load, at this time to change the power frequency, such as the current frequency down, the motor armature rotating magnetic field speed will decline, the rotor conductor cutting magnetic field speed decreases, turn from the induced potential , The rotor current decreases, the torque decreases, the load on the shaft does not change, the torque will be less than the load resistance torque, the motor rotor speed decreases, the rotor conductor cutting the magnetic field line speed increases, the rotor induced potential increases, the rotor current increases, The torque rises until it is equal to the load resistance torque, and the speed is smaller than the original. After stabilizing the work, the torque of the motor is the same as that of the original. (The motor torque is the same as the load torque, the load is constant and the motor torque is not changed)
- Q: How to make the motor speed (control speed), can not use frequency
- In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
- Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together
- Corresponding to a phase of the branch of the IGBT inverter module generally appear in pairs
- Q: First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- In the inverter in the following 18.5kw inverter will bring their own braking unit for some special occasions, such as the inverter at high speed due to production needs, must be 1 second, or less time to stop, in the stop when the frequency The internal DC bus voltage is too high, the inverter will be reported over-voltage fault, in the positive and negative connected bk-dk connected to a resistor to the inverter discharge, the inverter will not report over-voltage failure
