12 volt motors to esc,s by sonar Admiral   Posted: 9 days ago
The esc stuff is all working now. So i have just hooked up a LM2577 Voltage Booster input 3.5 - 30V, output up to 30V adjustable The idea is to have 24 volts battery input and the output stays at 12 volts. Having just said that it has come from action electronics and does not work .....Again. So I will have to stick with 12 volts .... so far as electronize esc,s go there heavy duty and also used so I have been told on the robots used in robot wars..

MFA Torpedo 850 motor by sonar Admiral   Posted: 16 days ago
At long last I got there. These say they are For 540 dual motor or single motor So for an 850 torpedo it is a no go.. I think I will have to stick with these from

MFA Torpedo 850 motor by camyaj Chief Petty Officer   Posted: 16 days ago
I use these in my S-Boot and PT boat both driving 3x motors ie MFA 850's and Graupner 600's those Blue or pink ones I had trouble with as with Not electronize but the other ones.They are car ones and you could probably get similar ones in the UK . They may be chinese amps but they handle 40amps plus no bother

MFA Torpedo 850 motor by Threelegs Chief Petty Officer   Posted: 16 days ago
I have used Electronize ESC driving MFa 850's in my 54 inch Arun for 5 years with no problems and am putting the same system in my Tyne. As to cost, what is reasonable?

MFA Torpedo 850 motor by Dave M Fleet Admiral!   Posted: 17 days ago
Hi Mark I was refering to the Blue as shown in the link posted by Sonar, I should have made it clearer that Electronize are brilliant and I have never seen or heard of any problems. Dave

MFA Torpedo 850 motor by jarvo Fleet Admiral!   Posted: 17 days ago
Hi Dave M, the Electronize ESC's i was refering to are good for 24volts and i think 30 amps, the other reference was to the blue chinese esc's that had a nasty habit of smoking Mark

MFA Torpedo 850 motor by jarvo Fleet Admiral!   Posted: 17 days ago
Hi Sonar, if you are running 2 motors, make sure you have good capacity in hand, these are powerful motors and need a good ESC to handle them, i used one with a chinese "50amp" esc and it produced magic smoke within a few minutes, changed to an Electronize and its run for 2 years now Mark

And now it is ESC time by Dave M Fleet Admiral!   Posted: 22 days ago
Hi Sonar I have been building electronics for many years as a hobby so am speaking from experience. The circuits you mention are for Forward only so may not suit if you require reverse. As it happens I am repairing an Electronize VR ESC and there are two large Schottky diodes protecting the MOSFET. The motors seem to be designed for industrial use and are very similar to car heater fan motors which I have used in my model tugs and damaged the MOSFETs in the ESC. Not all motors have multiple poles, which appear to be the main culprits. If you have a problem at least you can go back to the supplier and ask for your money back. I am sure Engel is perfectly legitimate and provides a good and efficient service and I agree that PayPay is a secure payment method. However the site connection is insecure and any personal or financial details you provide on line to the website be it for card or PayPal will be visible to anyone to intercept. The https in their address is incorrect and could well lead you to believe the connection was secure. I think Doug has identified the motor manufacturer and the motors may be end of line stock being sold by Engel. It certainly looks an impressive motor. Dave

And now it is ESC time by Dave M Fleet Admiral!   Posted: 23 days ago
Hi Specs say 180Watt so 15amp max at 12v. I suspect the actual stall current is somewhat higher - a wattmeter connected between the battery and motor whilst briefly stalling the motor with a wooden clothes peg should give an indication. I do mean momentary unless you want to cook the motor or wires! The Electronize will work up to 24 volts which would halve the current and may be a better solution. I was going to look on the site and see if they suggest an ESC but my McAfee warned me off- don't know why. This is a commercial motor and from its pic I suspect high current. It's also possible that it is multipole and may be generating lots of back emf which may need some fast Schottky diodes adding to the ESCs to protect the MOSFETS. I would check with the tech guys at the ESC suppliers to see if they recommend their product for this motor. Dave

And now it is ESC time by sonar Admiral   Posted: 23 days ago
Hi These are the motors. Not much info on them. But they are large and I can also replace the brushes when required. Big motors and they work very well in big models I had the Action stuff dual ESC and melted the p94 still awaiting a return email response from them three days ago. In the meanwhile as you say two esc's are more than likely better. Two from Here They seem to have the stuff that I have reliably been informed will do the job. So a few weeks time And I will be able to see how they go..

Using old motors by Dave M Fleet Admiral!   Posted: 2 months ago
Hi Martin I see from your profile you are in a rural area so you may be OK with your rc gear. ESCs can be expensive but generally work well. You will need a brushless type and both Electronize and Mtronic should work. I suggest you look them up on the web and either send an e-mail or ring them up to see what they suggest for your motor. Both allow you to set the nul point to your tx and require the minimum of programming to set up. Perhaps your friend could visit his loft and let you have one of his Bob Bords. I have not seen any advertised for many years and I disposed of all I had to friends who were still using. Good luck and please keep us posted with your progress. I would be interested to hear how you fare with the old rc gear. Dave

Original Aerokits Solent Lifeboat by Dave M Fleet Admiral!   Posted: 2 months ago
Decided to sail the Solent so took some video to share. Uses 2 Bhuler 12v brushed motors with 4 bladed 45mm PropShop props and 12v 12AHr SLA. Twin Electronize ESCs. Radio is Futaba 6Ex but I will probably change to the Taranis so I can get better control using some bespoke Tx settings to co-ordinate the props and rudder. Lifeboat crewe had been on a night out so not quite vertical. Aplogies for the shaky video, it's difficult to sail and video at the same time.

2 motors 1 esc by figtree7nts Fleet Admiral!   Posted: 2 months ago
Hi Sonar, Why not try two Mtroniks Viper Marine ESC! Or Both ESC's Available from Cornwall Model Boats, Just an idea Ed

2 motors 1 esc by Dave M Fleet Admiral!   Posted: 2 months ago
I have used this type of motor and they work well. If you are after torque then a five pole motor will give more. You are running at excess voltage so they will exhibit some stress if run at full power for any length of time. You should measure the current at 12v to see what is being drawn, I believe mine when connected and running free used to draw about 2.5 amps on 12v. It will be considerably more under load. I used three 0.1 uF capacitors across the terminals and case as they will spark at the higher voltage. Do also make sure that all your (dirty) power wiring is well clear of any servo wires and the rx and aerial. They can be quite current hungry and I used an Electronize ESC on each motor. Any good 20/25 amp ESC will be suitable but if you are using two and they have a built in ESC you need to remove the red (+ve) wire from one ESC lead to the Rx. Good luck and please post details of your final choice and experience. Dave

Alternative motors by Dave M Fleet Admiral!   Posted: 3 months ago
Hi Sonar Used to be very popular with the model Tug fraternity. I had two in my Eldergarth (4') and they worked fine. They are able to turn large coarse bladed props with ease and do not normally require any cooling. I used a couple of Electronize ESC's but any 20/30 amp make should be OK. They are not fast revving so most suited to Tugs, workboats, cargo vessels and fishing boats. If you have a fast boat they would not be suitable. Weight may also be a problem in smaller models
