- Q: Motor 2 pole and 4 pole in the inverter with what set to show
- There are parameters for the number of motor poles / pole pairs or the rated speed of the motor in the inverter parameters
- Q: Can different brands of laptop power adapters be generic?
- 1, strictly speaking, different brands of laptop power adapter is not common. Even if the logo on the voltage and current are the same should not be mixed, will cause the power interface or motherboard failure or even damage. 2, with the same brand of different models of the power can be used temporarily, but should not be used for too long. 3, the cottage power adapter is best not to buy the use of hidden dangers, including spontaneous combustion and explosion, try to use the original power adapter.
- Q: Notebook power adapter on how to look at power
- Power and work voltage power adapter will be identified, you only need to distinguish between input and output on the line, the input refers to the utility power supply support, and now are generally 100V ~ 240V, so you can use in most parts of the world,
- Q: 2 pole 0.75 kW motor can increase the speed through the inverter?
- 2-pole motor speed of about 2900 r / min or so, 4-pole motor speed of about 1400 r / min or so, which are in the case of 50HZ,
- 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: What is the principle and implementation of the inverter?
- AC-DC is relatively simple We know that the diode has a one-way conductivity You can use this feature of the diode into a bridge So that the other end is always flowing into the other end is always out of the way it gets the voltage sinusoidal change of the DC If the need for smooth DC also need to be rectified Simple method is to connect a capacitor
- 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: What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
- Motor speed and frequency of the formula N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (seconds); F - power frequency (Hirsch); P - pole pairs of motor rotating magnetic fields. China provides the standard power frequency f = 50 weeks / second, so the rotation of the magnetic field of the size of the theoretical diameter only with the magnetic pole. The number of pole pairs is large, and the rotational speed of the rotating magnetic field is low.
- Q: 90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
- The number of poles of the motor and the inverter is not very different, the difference is the motor speed is different
- Q: Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
- Note that the quality of the inverter is not ye, and now this situation is already very rare, it is recommended to replace the inverter brand, you can use Bosch Rexroth, the British Witten, Huichuan, Senlan, Haili Pu, Ou Rui, etc. Branded.
