Most economic way to get Power to a Gate Motor 

Glad it was helpful!

I use 3D Studio Max for the 3D animations and stills and Adobe Illustrator for the 2D Graphics.

It depends on how many amps your opener draws. A rule of thumb is to keep the load within 80% of the capacity i.e. if the gate draws 10 amps, for example, you'd need 10 amps/80% = 12.5 amps, so a 15 amp breaker with 14 gauge wire would be sufficient for this example. Make sure you're using the appropriate wire/breaker combo. 20 amp must have 12 gauge, 15 amp must have 14 gauge.

You are correct the more speed the less torque with low voltage DC motors, although overall torque, speed and efficiency of a low voltage DC motor is much better than a single phase AC motor with the same power.

@@automaticGatesExplained thank you for the quick response. So as an example, if you have a 300 watt 240v ac motor wouldn’t it draw less amps than a 24v motor with 300 watt rating? Making the high volt option more cost efficient by reducing conductor size?

An AC motor draws more electrical power than a 24VDC Motor to provide the same amount of mechanical power output because single phase AC motors are only about 30% efficient, where as 24VDC permanent magnet motors are 70% to 90% efficient. 24VDC motors normally have a built in transformer to go from 240VAC to 24VDC so power cable size to the gate will be the same, because it is determined be electrical regulations. If running low voltage power cable to the motor from a house this will require basically the same size cable up to a certain distance and a thicker cable for longer distances because there is a greater voltage drop.

@@automaticGatesExplained thank you for the help 👍

Low volt running too close and parallel to higher voltage gets an induced current. This especially affects comms data speed.

Okay just checked the Electrical safety code of practice for Queensland Australia, which is where I am from and for any voltage higher than 50VAC or 120V ripple free DC there must be a minimum cover of 100mm of 20MPa concrete or the equivalent, so here it is legal to do as I have suggested but then elsewhere it may not be. I would like to point out to all concerned that installing mains power should be done as per electrical code for the area where the work is being performed.

What if it was a 300mm slab.? Got to say I do this for a living and this guys movies are great and takes a lot of effort. Also I’d like to add he knows his job. Great movies, great guidance. Would really like to do a few jobs with this guy I think I’d learn a lot.
