- Q: The relationship between the power supply of the notebook and the battery
- The relationship between the laptop power adapter and the battery should not be called a power supply relationship, both of which are devices that power the notebook host. The basic relationship between the power adapter, the battery, and the host is as follows:
- Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- Soft starters and frequency converters are two completely different uses of the product. The frequency converter is used for the need for speed control where the output not only changes the voltage but also changes the frequency; the soft starter is actually a voltage regulator for the motor to start when the output only changes the voltage and does not change the frequency. The frequency converter has all the soft starter functions, but its price is much more expensive than the soft starter, the structure is much more complex. Soft starter (soft starter) is a set of motor soft start, soft stop, light load energy saving and a variety of protection functions in one of the new motor control device, known as the Soft Starter abroad. The softener uses a three-phase anti-parallel thyristor as a voltage regulator, which connects it between the power supply and the motor stator. This circuit, such as three-phase full-bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor gradually increases, the motor gradually accelerates until the thyristor is fully conductive, the motor works at the mechanical characteristics of the rated voltage, smooth start, reduce the starting current and avoid starting the overcurrent trip. When the motor reaches the rated speed, the start-up process ends, the soft starter automatically uses the bypass contactor to replace the completed thyristor, providing the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and prolong the service life of the soft starter , To improve its efficiency, but also to avoid the harmonic pollution to the grid. Soft starter also provides soft stop function, soft stop and soft start the process of reverse, the voltage gradually reduced, the number of revolutions gradually reduced to zero, to avoid free-wheeling caused by the impact of torque. How the frequency converter works
- Q: On the notebook power adapter output current and voltage issues
- This current is the maximum current value of the adapter output, Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.
- Q: My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
- Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
- Q: What is the principle and implementation of the inverter?
- How the inverter works: 1. DC can be converted into alternating current through the oscillation circuit 2. The resulting AC power is then boosted by the coil (in this case, the alternating current of the square wave) 3. Rectify the resulting alternating current to obtain a sine wave
- Q: Do you need to rectify before switching?
- There are two ways to convert frequency, that is, cross and cross the intersection, the latter need a direct current, need no rectification, depending on your DC situation.
- Q: Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,
- May be mechanical part of the card, try idling motor.
- Q: Inverter principle eff23
- The basic principle of the inverter The inverter is a device that converts the power frequency (50Hz or 60Hz) into AC power of various frequencies to realize the variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the alternating current into direct current and DC Circuit rectifier circuit output smooth filter, the inverter circuit will reverse into the DC power.
- 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: 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.
