Q: The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?: can use. But in the inverter "motor parameters" to be some changes. Such as the number of poles, rated current.

Q: Notebook power adapter on how to look at power: It should be noted that there are many in Japan to buy a notebook or over there in the parallel imports, input only support 110V in China is not used, because the Chinese standard is 220V. Now the subject is 90W 20V. Output voltage and power will be identified, such as the target for the 90W 20V, that output power is 90W, the output voltage is 20V. If only the output voltage and output current are identified,

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?: The frequency changer mainly consists of rectifying (alternating current direct current), filtering, re-rectifying (direct current alternating current), braking unit, driving unit, detecting unit micro-processing unit and so on. Motor asynchronous speed expression bit: N = 60 f (1-s) / p (1) Where n --- the speed of asynchronous motor; f --- the frequency of asynchronous motor; s --- motor slip; p --- motor pole pairs. From the formula (1) we can see that the output speed of the motor is related to the input power frequency, slip rate and the number of pole pairs of the motor. Therefore, the direct speed regulation mode of AC motor mainly has variable speed (adjustment P), rotor Resistance speed control or cascade speed or internal feedback motor (adjust s) and frequency control (adjust f) and so on. And we now use the most widely used is the frequency control, from the speed n is proportional to the frequency f, as long as the change in frequency f can change the motor speed, when the frequency f in the range of 0 ~ 50Hz, the motor speed adjustment range is very width. The inverter is to change the motor power frequency to achieve speed adjustment, is an ideal high efficiency, high performance speed control means.

Q: 5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?: Can not be exceeded Although the inverter can run out of the motor rated speed as the motor will soon burn You want your running speed of 2m / s you have to run 5m / s so go eggs do not pull the

Q: What is the single axis of the inverter and multi-axis applications: The frequency changer mainly consists of rectification (alternating current direct current), filter, re-rectification (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.

Q: The Schneider inverter reports the nlp command: Current transformers are also possible, or power supplies

Q: Can the HP laptop's power adapter be universal?: Power supply low-voltage plug to the same, the voltage to the same, the current is greater than or equal to can be used

Q: How do I select a drive? Which brand is better: ??8, drive explosion-proof motor, the inverter is not explosion-proof structure, the inverter should be set in a dangerous place outside. ????9, the use of inverter drive gear motor, the use of the gear by the part of the lubrication part of the lubrication control. When lubricating oil is lubricated, there is no limit in the low speed range. If there is a high speed range above the rated speed, there is a risk that the lubricating oil may be used. Therefore, do not exceed the maximum speed allowable value. ????10, the inverter drive winding rotor asynchronous motor, most of the use of existing motor. Winding motor and ordinary squirrel-cage motor compared to the winding motor winding impedance is small. Therefore, it is prone to overcurrent trip due to ripple current, so a frequency converter larger than the normal capacity should be selected. General winding motor for flywheel torque more occasions, in the set acceleration and deceleration time should pay more attention.

Q: How to make the motor speed (control speed), can not use frequency: If you use AC asynchronous motor speed control in three ways: 1 / variable speed control. By changing the motor stator pole pairs to speed, not the linear speed for the sub-file speed, the motor structure and electrical control more complex. 2 / electromagnetic speed control. Driven by the magnet magnet, the electromagnetic coil through the variable size of the DC to speed, for the linear speed, but a waste of energy 3 / frequency control. Through the inverter speed, stepless speed regulation, speed control effect is good, but one-time investment. If the DC motor speed is to change the armature or the excitation coil voltage to achieve speed. Application in the relatively high demand, a one-time investment is relatively large
