LEGO Technic 8293 Power Functions Motor Set Review



The Lego 8293 build is a part of their Technic Creations, and is officially known as the Lego Power Function Motor Accessory Set. There are nine pieces of this build in total. The build weighs at least 181 grams, and contains a product dimension of 26.2 cm x 14.1 cm x 4.8 cm.

Despite its small size, these nine pieces have the ability to motorize and give life to your Lego Technic creations. The Lego Power Functions Motor Set contains nearly everything that is needed to make your Technic creations a moving reality. The Lego 8293 is a supplementary power set that comes with its own battery box, a light cable with two bright LEDs, a medium motor, and a switch. This lets you power up your beloved Lego Technic builds.

Apart from those, the 8293 also has its own set of extra pieces, allowing you to include in new features and functions right into your models. The cable and switch measures around nine inches, or 25 centimeters long. The switch, which includes the orange switch, is over three centimeters long and under three centimeters high, and two centimeters wide.

The battery box has a measurement of six centimeters (two inches) high, eight centimeters (three inches) wide, and three centimeters (one inch) deep. Its light cable is over 39 centimeters (fifteen inches) long.


The M-Motor measures over four centimeters wide (one inch), and two centimeters high (one inch), and two centimeters (one inch) deep. Together with the cable, it’s at least 26 centimeters (ten inches) long. You can use the same motor set to give life to your Lego Technic models – But only if it’s the Lego 8294, 8297, 8275, and 8295. You can find any of these models at your nearest toy store or Lego store.

There are extra pieces included inside the 8293, which are meant to include brand new functions and well as features to motorized models. You will also need six AA batteries for it to function well.


This kit is wonderful for aspiring engineers. If you have a child who is very much into building Lego’s Technic sets, and has created plenty of box-kits and made their own creations from scratch, then this is the perfect way for them to practice.

The motor contains two stitches inside them, so you can utilize them both for tandems, or for each one of their own. You can also use one for lights or the other one for complete movement, so they can both be utilized independently from a similar battery pack. These switches both have three points of entry for your lever, so you can mount them on either side, the top, or under the build – It all depends on where you want to have the switch attached in.

The battery unit uses at least six AA batteries. Some users have taken to applying alkaline or rechargeable batteries for the 8293. Perhaps the only small gripe here is that one battery located on each side is slightly tricky to get rid of. However, if you utilize a 1 x 6 flattened piece of Lego (like one of their baseplates), you can easily pry it out. It’s still impossible with using only your bare hands or fingers. Make sure that the 1 x 6 is kept attached to the pack, because it really does come in handy when you have to charge it.

Another issue that some people have had with the 8293 is that there’s only one motor contained in the pack, and a singular set of lights. This limits your freedom to done movement of action both backwards and forwards, unless you have decided to create your own gearbox for your builds.


Some people have decided to purchase the Lego 8293 because they want to start a Lego Technic collection that uses Lego’s own Power Functions. This set was just excellent – First off, the box is pretty large as compared to its small amount of content inside… At least 1/3 full. There’s also one instructional booklet found in the box, along with the M-Motor, a battery box, a pair of LED lights, a control switch, and a bag filled with Lego bricks that you can attach to past Technic builds.


The instructional booklet reveals all of the necessary information that you have to know about the 8293 – Including the batteries, as well as the other sets that are meant to be used by the Power Functions.

M-Motor, also known as the medium motor, measures six studs in length and at least three studs high and wide. It moves really quickly despite its small size. Because it’s the smallest motor in the full set, you might expect it to put out a terrible performance, but it’s actually the opposite. There’s plenty of toque, not to mention the machine itself is very robust and strong. It’s a very good motor for Lego mechanics, small cars, and machines.


The 8293’s battery box contains at least eleven studs in length, four studs wide, and eight studs high. There’s over six variants of AA batteries or nine volts involved. Located on top is an orange switch that serves as an on and off button. It can reverse its content, so the vehicle could move forward or in reverse – Another cool feature found in Technic cars.

There’s also a control switch included, which measures four studs long, two studs wide, and three studs high. If you are able to switch on the battery box using the attached control switch or with the lights and motor attached to it, then nothing will happen to your Technic vehicle. You will now be able to pull forward the orange lever located on top of the switch – This will make the motor move on forwards. Or you can pull back the lever, which does the opposite, and also reverses the current. If this is achieved with the lights, the machine just switches on, no matter which direction you pull the lever in.

The 8293’s lights could also slip inside the Lego Technic’s own beams, or inside studded beams too. Right in the middle of the cord is a separation, which means that the lights themselves are all separated from each other. And since they’re made from LED, they do give off a rather bright light.


Inside the box is also a tiny bag of pieces that contain the usual Lego Technic axles, gears, and three variants of universal joints. This set is actually great, especially if you’re a fan of Lego’s Power Functions.

The parts found inside this set are good for getting your Technic models to move. And in certain cases, you can even fit them to the main model of a Lego Technic kit – All you have to do is to follow certain instructions. Adding an upgrade to your build using Lego’s Power Functions does include plenty of play value to the model itself.

The main value for cash that comes from the Lego 8293 has been hampered by its huge price. If you add in the cost of the main parts, including the switch, the light brick, the battery box, and the motor, it’s only around 71 percent of the total set price. The few remaining universal joints and gears aren’t worth more than a quarter of the difference, so the price should be lessened. A lot of owners have suggested that you check the Technic set you’re about to upgrade to using the Power Functions. If all of the parts aren’t used, then you just have to purchase the individual parts instead. Apart from that particular problem, the portions are actually quite good.

Its battery box takes at least six AA cells. Coming from a certain position, the cell is hard to remove once it’s time to change them, but using a screwdriver from the positive end of the cell could remove it just as easy. A person once purchased three of these kits, as well as a bunch of other Technic building kits, and each one of them came with their own battery boxes. You can use the empty cases to change the 9V output of the Lego’s transformer power source, right down to the Power Function’s own protocol. If you happen to have a 9V train controller, or any other source that could be connected to a 9V plug, then you can utilize a Power Functions cable (this comes with the Lego 8886 and 8871) to attach the 9V plug to an empty battery box. And if end up connecting a Power Functions IR Receiver (set 8884) to its battery box, the switch located on the battery box will still end up attaching the power source to the 9V and 0V lines to operate the IR receiver. This works in only one way around, so you have to check the polarity first before you leave it for at least one second, or even two. If the green light that comes on the IR receiver refuses to light up, then this simply means that you attached it on the wrong way around. Move the battery box and switch it on the other side.
