Today we’re diving deep into the fascinating world of RC brushless motors, specifically exploring the intriguing differences between Y-Wind and Delta-Wind configurations. If you’re an RC hobbyist, understanding these distinctions can be crucial in optimizing your motor selection for your unique applications. So, let’s uncover the truth behind these motors and which one might be the right choice for you.
Understanding the Basics
First and foremost, let’s address the fundamental concept behind these motor types and their impact on RC hobbyists. To provide a fair comparison, we’ll consider motors of equal size. When we wind a motor with a Delta configuration and give it one turn of wire, we’ll immediately notice a significant difference: a higher Kv value. This higher Kv value means that a Delta-Wind motor can draw more current. However, there’s a trade-off. A higher Kv motor can’t handle as much voltage. So, you get more current but sacrifice potential voltage.
On the other hand, the Y-Wind motor will have a lower Kv, meaning it draws less current but can handle a higher voltage. When you multiply the voltage and current, you get the wattage value. Surprisingly, when you compare the wattage values of both Y-Wind and Delta-Wind motors of the same size, you’ll find that they have identical power potential. It’s a balancing act between current and voltage.
In the image above, you can note that the Delta wind has only one coil between any two of the connectors A through C. The Wye wind on the other hand, contains two coils between any 2 connectors A through C. This is where the electrical difference comes from.
Choosing the Right Motor
Now, the big question arises: which motor should you choose? Y-Wind or Delta-Wind? The truth is that for most RC hobbyists, it doesn’t matter. Both motor types offer virtually identical performance. The subtle differences, however, are worth exploring.
When it comes to motor selection, the key factors to consider are the Kv value and the desired power output for your specific application. These factors far outweigh the choice between Y-Wind and Delta-Wind configurations. Motor manufacturers offer both options to cater to a wide range of preferences and applications, primarily focusing on different Kv values for the same motor size.
Wye vs Delta Subtle Difference
One subtle difference worth mentioning relates to timing. Y-Wind motors tend to perform best with the lowest possible timing setting. Increasing the timing may boost RPM but at the expense of generating excess heat. In contrast, Delta-Wind motors prefer minimal timing adjustments, leaving little room for timing advancement. If you’re seeking higher RPM from a motor, it’s advisable to consider a different Kv motor altogether.
Final Thoughts
In conclusion, the choice between Y-Wind and Delta-Wind motors should primarily depend on your specific Kv and power output requirements. The select the wind that makes the most sense regardless if you end up with a Wye or Delta wind for that specific motor Kv. Don’t get caught up in the intricacies of motor winding configurations. Focus on selecting the right motor for your needs, and from there, fine-tune your RC experience based on your application and performance preferences.
We hope this article has shed light on the truth behind RC brushless motors and their winding configurations. Remember, the key to success in the RC world lies in making informed choices that suit your unique needs.
