Q:The laptop's power adapter is broken how much it costs
Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
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:Jd1a-40 motor speed controller and how to connect the motor
First, variable pole alignment speed method This method of speed control is to change the stator winding winding red method to change the cage motor stator pole pairs to reach the speed control target, the characteristics are as follows: This method is suitable for production machinery which does not need stepless speed regulation, such as metal cutting machine, lift, lifting equipment, fan, water pump and so on. Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing the speed of its synchronous speed control method. Frequency converter system can be divided into exchange - DC - exchange converter and exchange - exchange inverter two categories, most of the current domestic use of cross - straight - cross frequency converter. Its characteristics: This method is suitable for the requirements of high precision, better speed performance.
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is no load, the demolition of the gearbox is the same can be run.
Q:Please recommend a high performance laptop power adapter?
See what model you notebook ah, according to your power adapter voltage, rated current to match.
Q:Yasukawa inverter reported bb code that is the reason why the base blockade?
Not a drive failure! Is an external signal problem.
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
Depending on your question may be the problem that the laptop's internal lines may be short-circuited 1, you can go to the video online to find the same type of machine disassemble video and then repair their own 2, get to the maintenance of the place to get on nothing
Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
First, the inverter is no problem, I used so much to meet your needs       But to see if your motor can run at high speed, or whether the load is small, the power to have a general amount of redundancy. 6-pole motor synchronous speed of 1000, to meet your use to be transferred between 2000 or 1900, that is to say the frequency converter output frequency to be transferred to 90 to 100HZ.       Constant torque load is no problem, but the fan torque load to be a small job.
Q:Can the laptop power adapter be generic?
Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
Q:How to choose a power adapter
With the seller to an output 20V ,, 0.5A IBM single hole power adapter
