For simple terms, A 'BEC' (Battery Eliminator Circuit takes power from your battery directly to your receiver and servos. This is all inbuilt into your ESC so you dont have to buy one externally.
For this product, you could power 6-8 9gram servos without putting stress on the ESC.
Reasons why I use a BEC is because I always like have a failsafe so I know that if my ESC burns out, I will still have control of my control surfaces. Also it makes everything run a lot cooler.
There has to be, no way to control it otherwise. Even the ones without the internal bec have a servo lead. I see what you mean looking at the picture, though. It looks like it doesn't have one. I have many of these in the 60 Amp version and they are fine trouble free units. I highly recommend buying the programming card. Well worth the money.
Spare yourself the trouble and the endless beeping, buy the programming card. It is the round one shown above for 6 bucks. If you can't wait, try one of the other esc's files, like the 60 amp one of the same type. It should be the same.
To be honest there isn't much between them both in way of which is better,but i'd tend to go with this one as it has more Amps but having said that i find the plus series of ESC's to be bullet proof,but that doesn't mean these are not because i've had no trouble with them,i'm now about to buy some more as the 60amp plush are out of stock. *-)
I finally bought the Plush 60A and 30A. They are awesome but they don't have governor mode and that's a must have for heli. So I ordered YEP 60A. Still waiting to receive them though. Anyways thanks for your reply.
Trying to run a Turnigy SK3 5055 430 kv on a 3S LiPo or two in series, i.e. a 6s. With throttle stick to the bottom nothing at all happens, if throttle all to the top I seem to get into the programming mode and am getting a plethora of different beeps. If during the beeps I draw the throttle back it confirms this by some other beeps. Although nothing really matches the only data sheet i have found, which does not explicitely mention this ESC type
Any idea how I can just start to run the motor. Thanks!
Pulse Width Modulation.
A brushless motor is, essentially, a 3 phase motor operate on square waves instead of sine waves. Here comes the speculative part. I THINK the pwm frequency is how fast the ESC switches as it build up the square wave that drives the motor. The drive signal to the motor consists of three waves 120 degrees out of phase. The shape of the wave depends on both the throttle position and the pwm frequency. My GUESS is that higher rpm/kv motors require higher pwm frequencies.
Sorry I can't give you a more detailed explanation.
Close but PWM creates a sine wave similar to ac by switching the dc at varying pulse widths to increase the average voltage and then decrease it again so that the average voltage forms a sine wave simialar to ac. Difficult to explain without diagrams but check wikipedia for good basic diagram and explanation
Super Preis Leistung, kommt in einem Segler zum Einsatz. Hatte einen der ersten Serie von diesem ESC, dieser ging leider (oder zum Glück) bevor er in seinen ersten Einsatz kam,in Rauch auf. Hoffe nun, dass der Neue seinen Dienst besser leistet.
the hobby king speed controllers are one of the best but a little over priced but they do the job well and they are made very well this one weighs a lot and the size did surprise me a lot but as long as it does its job i cant complain i just make sure i place it in the rite spot to balance the plane with the battery
