Easy Way to Test Short Circuit in Brushless Motors without using Tools

Eltronicschool. - You should make sure when using brushless motor in best performance before using brushless motor like for your drone or quadcopter. In here we will give you easy guidance for testing any short circuit in brushless motors without using any tools needed.

Source: fpvmanuals

If you understand about how brushless motor work, it is become asset for you to do troubleshooting this motor.

In brushless dc motor can generate power using electromagnet that can spin the motor pushing and pulling the magnets attached the bell of the motor. So, when you want to generate power you only need spin a motor by your hand easily.

And now you can follow steps below to test short circuit in burshless motor easy way only using your hand according Fpvmanuals site.

• You can create resistance within the brushless motor with short any two wires together when you try to spin the motor by your hand.
• Make sure that when all the wires are separated as there is not a complete circuit will make a brushless motor should spin freely.
• The last, it’s likely that your motor has an internal short circuit when  the motor resists your rotation regardless of the wire connections.

So, with little understanding a brushless motor work, it is make easy to test brushless motor work perfectly like steps above.

Guide to Choosing Your First Brushless Motor by Associatedelectrics

Eltronicschool. - Do you need information on how to choose your first brushless motor that presented by Associatedelectrics. This article has been publishing on E-bay since April 24, 2014 and now we will give you summary about this article again.


This article show you 5 elements that important you should know before you choosing your first brushless motor as follow: Brushless Speed Ratings, Brushless speed controls, Sensored or Sensorless, Brushless Advantages, Brushless Motor Maintenance. And below the explanations.

A. Brushless Speed Ratings

Unlike brushed motors, springs and brushes will not be a consideration with a brushless motor. However, like brushed motors with many turns and winds, you’ll find a wide variety of brushless motors in various turns or KV ratings.  Let’s look at these briefly. 

No one standard exists for measuring the speed of the brushless motor. Some manufacturers measure the speed by turns. Other manufacturers use a KV rating. These terms are important to you because they will help you choose your motor’s speed. A sensored motor is marked by the amount of turns it has: 21.5,10.5, 9.5, 8.5 -- the lower the turn count the faster the rotor spins. But a sensorless motor is referenced by KV. 

With KV, the higher the number the faster the rotor spins. As a comparison, a 10.5 sensored motor is similar to a 4300kv sensorless motor. When you look at specifications supplied by the manufacturers, you will see that they are very close in performance. A 10.5 brushless motor is roughly the same as a 3800-4300 KV motor, depending on the manufacturer. 

B. Brushless speed controls

Brushless motors must be run from a speed control designed for brushless motors. They will not run from a brushed speed control.  As with brushed motors, different speed controls will only handle those motors which fall into its range. For example, Team Associated's XP SC200 will handle motors from 17 turns and up. Obviously, the speed controls that handle a wider range of motors will be higher in price, so satisfying your “need for speed” will impact your wallet. Running a motor out of range of the speed control can cause damage to both. Be sure to review the manual that came with your speed control to find specifications. 

C. Sensored or Sensorless

In the sensored system, the motor includes sensors to transfer exact information to the speed control, making the sensor speed control more precise.  Sensored systems give the feeling of the vehicle responding accurately to even the smallest changes of speed. These motors are highly prized by experienced racers who are always looking for an edge in the competition. 

D. Brushless Advantages

• Higher efficiency 
• Longer runtime 
• More power 
• Maximum RPM 
• Better acceleration and performance 

E. Brushless Motor Maintenance

Because brushless motors require little to no maintenance, you can simply blow them clean by using canned or compressed air and then use a lightweight oil to lube the bearings and you’re good as new. Brushed motors require complete servicing every seven to ten runs or more frequently when racing to maintain the performance they had when new! Complete brushed motor service means disassembling the motor, cleaning the can and armature, lubing both bearings in the can and hood, re-cutting the commutator, deburring it,  reassembling the motor, installing new brushes and springs, and breaking in the brushes. to test different brush and spring combinations for the best performance for the type of racing that you are doing.

Reviewer Opinion

Now you can read more about the reviewer opinion below to know the satisfy using this ZJchao Outrunner Brushless Motor RC Accessories Kit.

• Howy on March 22, 2014, "I was skeptical but I wanted to buy all cheap stuff for my first quad copter build. I bought 5 just in case one showed up bad. The collet adapters do not always fit just right so I was tightening down a prop and I could still remove the prop even though it seemed so tight I might crack the prop. After another hefty turn the metal shaft on the adpater broke (cant believe the prop was able to take all that pressure). So what I did with the other motors was add a smidgen of epoxy to the collet/shaft so I don't have to worry about tightening them down so much..."
• Delrew on June 14, 2014, "These motors work well and have a good build quality. The prop adapters on the other hand are engineered to fail. The compression sleeve has no room to compress the clamp around the motor shaft. You can resolve this by ordering http://www.amazon.com/gp/product/B00AQBU1WA where the compression sleeve leaves around 20% and allows the prop nut to tighten to the motor shaft as it should.The ESC's came with a programming guide."
