15 de feb. de 2004 · If you can post your source and dsn file we'll have a look. Typically this happens when you externally wire a crystal etc. - this introduces an extremely high speed oscillator which bottlenecks the simulation and is completely superfluous anyway. Clock frequency is specified as a property of the microcontroller device.
12 de jun. de 2004 · hspice speed up simulation Besides fast options, autostop can help you as well. In addition, increase step for transient, AC,DC will help when too small is not necessary. Of course employing multi-cpu and use multi-thread job can make simulation fast dramatically.
11 de feb. de 2006 · 27. Trophy points. 1,308. Activity points. 2,986. Re: speeding ADS Just go to the task manager and in processes tab pick proper and give to it max priority, also do not tale a lot of points to run But of course you can do it with other 3D simulators and for sure they will be more faster (like HFSS, CST etc.) David. R.
24 de ene. de 2008 · bldc motor speed calculation. measure the time between two transitions: ttr. it's the time it takes to go 60 electrical degrees (or 1/6 electrical period) electrical frequency = (1/6) / ttr. multiply by 2xpi to get rd/s. multiply by number of pole pairs (P) to get mechanical speed. multiply electrical frequency by 60xP to get RPM.
As the demand for high-speed data transmission grows, the interface between high-speed ICs becomes critical in achieving high performance, low power, and good noise immunity. Three commonly used interfaces are PECL (positive-referenced emitter-coupled logic), LVDS (low-voltage differential signals), and CML (current mode logic).
21 de nov. de 2020 · 在主板上会有很多个风扇的接口，每个接口的作用是不一样的，机箱风扇的接口和CpU风扇的接口都是要接在主板上的，很容易出错，如果出现插错接口的情况，就会导致出现错误提示； 2、可以打开机箱检查CpU的风扇是不是接在主板上标有“CpU Fan”接口上 ...
19 de abr. de 2006 · For 220V DC motor 5 HP, BT152 SCR will be suitable which has current rating of 15-20A as my motor need 16A. Mmmhhh I'm not sure, but remember that a motor can use 3 times the nominal current at startup. Maybe you need >48amps SCR's. You should check it before you buy them 'cause they're expensive.
8 de ago. de 2008 · This sounds as though you want to examine 5 seconds operation of a circuit running at 1 GHz. It's an example of mixing micro and macro events. It becomes mismatched and unwieldy in simulation. (It is not a problem with real electronics, of course.) Consider trying a longer timestep. Also try a slower switching rate in your simulated circuit.
30 de jul. de 2004 · It is a single pole, fully variable rotary speed control from Ace Hardware model 5A-120 AC for ten dollars ($10). It fits inside of a standard electrical box. I have used it on various small motors and have experienced no problems so far. Ace Hardware package, product or skew number is 3027596.
The min-imum output common mode of LVDS (1.125V) is lower than the minimum input common mode of the HOTLink II CML receivers (1.25V), therefore the AC-coupling capacitors, C1 and C2 are necessary to remove the DC content of the LVDS output signal. The DC-restoration of the HOTLink II receiver will re-center the transmitted signal around VCC/2 ...
