Q: Is the speed of the motor controlled?: Slip motor is composed of ordinary squirrel cage asynchronous motor, electromagnetic slip clutch and electrical control device composed of three parts. Asynchronous motor, the stepper motor is used as the prime mover, and when it rotates, the armature of the clutch is rotated together. The electric control device is a device that provides the excitation current of the slip clutch excitation coil. Electromagnetic slip clutch, which includes armature, magnetic pole and excitation coil three parts.

Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?: Then the motor nameplate on the standard 2P, it must be 2-pole motor, synchronous speed = 60 seconds x frequency (mainland 50Hz) / pole pairs, you can also look at the rated motor speed, about 2940 rev / 60s, so the inverter Set the number of motor poles, is set 2 pole, I hope you can be satisfied.

Q: Laptop adapter heat: In fact, as long as the power adapter temperature is within the design range, that is, the temperature in the normal range, the general is not dangerous! So why is the power supply hot? What kind of temperature range is the normal range? Switching power supply conversion efficiency can only reach 75% -85% or so. The answer is here. Switching power supply conversion efficiency is high enough, it is still difficult to find a better way to convert. Switching power supply in the voltage conversion, a part of the energy loss, in addition to a small part of the loss in the form of waves, the majority of the way out of the heat. Switching power supply power is missing, the loss of energy is also missing, the power of the heat is also large. This is why the desktop power supply to add a fan for cooling reasons. We may wish to count, a 100W switching power supply, in the use of how much energy loss in the above!

Q: How to view your own laptop power adapter is how much tile?: There are signs on the power adapter, you look for sticky paper to write the voltage and current power. If there is no write power, the direct voltage multiplied by the current is the maximum power.

Q: What is the base blockade in the drive?: After the base is blocked, the power tube is fully closed to protect the power tube.

Q: Do not the laptop directly connected to the power adapter?: "Notebook do not power adapter", can only use the internal lithium battery power supply work. It can not directly use 220V AC power supply for it. 1, because the notebook product design power supply standard, is to use the matching power adapter power supply. That is, the power adapter will 220V civilian AC, rectifier filter, and then converted to low-voltage 19V DC, for the notebook to provide power supply;

Q: Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?: You can only use constant torque type of inverter. Motor selection frequency conversion motor. Driving is no problem

Q: What is the difference between the collector and the emitter mode?: This physical structure is intended to facilitate the need for positive enlargement.

Q: 18: 5 kilowatts bipolar multi-pole pump motor with inverter: If you worry about the small, with 18.5KW is far enough.

Q: Variable frequency conversion frequency difference characteristics based on,: Pole is the pole pair. So that the synchronous speed has changed, you can speed, but can not smooth speed.
