What Kind Of Motor Should I Buy?3 months, 1 week ago | 3 Replies
Wheel hub motor
The hub motor is exactly the same motor as you read; They are electric motors that act as the hub (usually the rear wheel) of a wheel. When they spin, the wheel spins. They require no other moving parts, produce almost no detectable noise, and come in a variety of different fixed-speed configurations. If you are confident and have a bulletproof battery and an ESC case, you can even enter a skateboard park and ride like a regular skateboard. Since hub motors only use sleeves as wheels, the types of wheels you can purchase are limited. However, replacement sleeves are easy to find, and new styles are coming out all the time. In addition to being silent, a unique feature of the hub motor is that if the battery dies, it will still push your circuit board properly. Depending on your motor configuration, you can even charge the battery this way.
The belt-drive motor has a brushless motor with a pulley on top that is connected via a belt to a larger pulley on the wheels. Belt drives provide you with a variety of replaceable gear ratios, high torque and speed options. If you live in hilly areas or plan to use a mix of road and off-road, these can make excellent engines. Some DIY all-terrain riders convert their belt drive to a chain drive to improve durability. You can run them as single-motor or dual-motor configurations. They also tend to have a lot of moving parts that need to be adjusted and may vibrate loose or move unevenly. Depending on your setup, the torque output from these little monster motors may require adjusting the motor bracket, belt and motor during and after a hard ride. But when dialing, the power will put a smile on your face. Aside from the high torque curve, the really best part about belt drives is that you can adjust any system for use on almost any skateboard truck, any skateboard wheel, or all terrain wheels that can be mounted with pulleys. The online community is huge, and if you need help and don’t have crazy questions that aren’t welcome, there’s plenty of support.
Direct drives provide the best performance of hub and belt drives because they have the high torque and high speed of a belt-drive motor, direct input to the hub motor, and therefore no belt, mounting seat or pulley. Acceleration is 100% adjustable and, like a belt drive, all power is transferred directly to the wheels. In addition to all the direct power, these motors tend to lose heat quickly, so running at higher speeds for longer periods of time makes them ideal for uphill racers. With these motors, you get the perfect combination of ease of use, fast acceleration and balanced power control. Best of all, you can use any skateboard wheel that can be fitted with an adapter, including all-terrain wheels and push-kicks, when you’re too stupid to recharge the battery at the last stop. Of course, there is no perfect motor for all situations, and direct drives have their drawbacks. Direct drive motors are large. Their relative size keeps them very low to the ground and vulnerable to damage from debris. Their jars are not bulletproof and even a small stone can cause damage. Riders who use pneumatic wheels on streets and off-road will benefit greatly from direct drive. For the brave souls who want to feel the power and run at low speeds on polyurethane street wheels, you’ll need to start learning how to sculpt and weave quickly.
Gear drives may seem new, but DIY Gear Head has been experimenting with gear drive systems for years. In most cases, gear drive systems are small, complex, closed, fixed gear systems with the best features of all of the above. You can change wheels at any time without a belt, and the torque of the belt drive is all in a compact system with enough room to tear apart mountains and cityscapes. Most of these systems are incredibly responsive and compact. Some incredible DIY all-terrain racing gear even has a variable transmission, but for the most part, you’ll find that a fixed transmission system is the norm. The biggest drawbacks of this system are gear noise that can be deafening to the most sensitive people (just annoying to the rest of us), complexity and expense. For many DIY manufacturers, these can be very expensive integrated drivetrain systems. But if you can afford it, it’s worth it. If you are a serious off-road driver and are in desperate need of a high-speed sealing system, then this may be the motor/driveline combination for you.
What functions should my motor have?
Before you can use the ESK8, you need to decide what kind of electric board you want to build. You live in the city. Don’t you often go up hills or trails? You can build a cheap but fast hubmotor board or single belt drive with lightweight batteries and place it on an old kicking tailboard or vintage pin taildeck and wear it out in style in the urban wasteland. Do you feel lively and like to get muddy? Then, giant twin-motor belt drives with 8 – or 9-inch multi-section AT wheels and inflatable tires, paired with the Trampa-style deck hanging trucks, will give you a real good time. Do you need speed? Long distance straight through downhill board paired with direct drive and 12S4P battery will push the back of your head eyes. Now that you have your dream, get it down on paper. Write down what style of board you want. Visit sites like Skateshred.com, Zumiez.com, or better yet, go into your local skate shop and see what they have to offer. Write down the style of skateboard you want to buy. This will be the beginning of your parts list.
A special note on this point, the skateboard has a wheelbase size, which tells you how much space you have in the middle of the skateboard where you have to put the battery, ESC case, motor, disco lights, etc. It helps to know how much space you plan to use before clicking the “pay now” button.
