VinceStylez asked Strong motor that can be interfaced with arduino?

I'm looking for a motor that could be interfaced with an arduino. I want to use it to move a sliding door so rpm speed could be slow. I just need enough torque to actually move the door. What kind of motors should i look into? And also, it would be great if they were weatherproof. What kind of DC motor?

And got the following answer:

A likely candidate is a cordless drill. These are available to more than one horsepower (intermittent rated). They already have gears, and a torque limiter built in. It is also easy to connect mechanically to a shaft using the chuck, and they are (mostly) low cost. The built in speed controller can be used too if the trigger is held in position to suit, or sometimes can be converted to a knob (potentiometer) setting. The main issue is they are more or less unspecified. The most important values needed are: Operating voltage (same as the battery for maximum speed). Operating current under the expected load. This is the minimum continuous current rating of the power supply. Maximum current when stalled (starting current). This is the peak current that the components and the power supply must deal with. The time involved is brief, less than a second probably, but may need to be included in the continuous rating because it is not brief by electronic standards. Some power supplies, especially switch mode types, have no reserve for this additional current so their voltage drops. Instead of a bulky power supply it may make sense to trickle charge the drill motor battery instead. These values are easily determined if you have a bench power supply with adjustable voltage and current to test with. The expected voltage is 12-24V range, and currents up to about 40A, depending on the voltage, the mechanical load and the motor. With a light weight door as a load, I expect moderate currents, and the speed control or voltage reduction can probably get the speed you want. Make sure you get a drill with a torque limiter (ratchety thingo). If this motor proves too small, use more gears (a worm drive maybe) to drive a larger door like a heavier sliding gate. The current drawn is several amps, so the Arduino digital output will operate a relay through a relay driver. It is possible to use a mosfet device for on - off control too, or for reversing, a H bridge is one solution, while another is two separate relays, one for on-off and one for reverse/forward. Relay contacts or semiconductor switches can be used in a H bridge circuit. See the first 3 links, but also search for others. Traps with H bridges: It is possible to short out the motor supply with a H bridge if the wrong two devices are switched on at the same time. Normally switch all off, wait a bit, switch the desired pair on. When a microprocessor powers up the outputs are configured in some default state. Whether configured as inputs or outputs they may be able to turn all 4 arms of the bridge on or partly so, during the whole startup (reset and boot) time, long enough to cause smoke. Some protection must be implemented that disables the bridge drive until the program is ready to control the bridge, first configuring the outputs correctly, then turning them off, ready for the first command to run the motor. Another output can be used to enable the control signals once the system is started. Some H bridges can be pulse width modulated to vary motor speed, so a slow smooth start can be achieved.. This is usually at a few hundred hertz, chosen to avoid mechanical resonances in the motor. Make sure the high current motor supply is properly fused at a little more than the expected run current. Use a slow blow fuse. Make sure you have a safety cutout feature in case someone (especially a kid) gets their head or finger caught in the door. Another source of motors and other useful components might be a garage door opener.

The relay interfacing perform exceptionally well with various applications that are precise to power distribution and protection. The relays include wide adjustment ranges with a scale that is definitely simple to read either in 3 or four digits based on the model. These relay interfacing help in rising the flexibility in the applications, lower the all round power and upkeep charges. There are actually relays which are employed for basic purposes which come in reputable designs with swift replacement options. And there are actually models that happen to be applied for industrial applications and heavier duty applications that function on massive loads. These merchandise are produced to meet the lifetime industrial handle wants in the applications.
Their most recent merchandise are the Time counter, Timer Delay, relay interfacing, Quick Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other people. The web page delivers a detailed description of every model in several categories of relay interfacing couplings and sensors. These solutions are extremely useful for high-risk applications. The relay interfacing are also offered with attributes like a number of timing ranges and functions. The organization is currently seeking agents and dealers who can promote and sell their factory produced products. They’re often on a lookout for creating new and more trusted items depending on the demands and requirements in the sector.
