Overview
The Spektrum Firma Sensored Smart ESC System is specifically engineered to be used with 6th scale Crawlers and Scalers, such as the Axial? SCX6™. Featuring advanced Smart connectivity, professional drag brake performance and torque control, all while being fully waterproof.
Like every component in the Spektrum™ Smart ecosystem, Firma™ Smart ESCs combine "plug-and-play" simplicity with the ability to communicate with other Smart electronics — together, creating the best-performing RC system for your vehicle imaginable.
Firma Smart ESCs do much more than regulate power. They function like a virtual engineer inside your model, providing a direct path to the vital operating data you need to reach peak performance. Firma Smart ESCs give you an extra layer of confidence that your electronics are all operating at their best.
With Firma Smart ESCs, you'll be better connected to your vehicle than ever before — without installing extra components that all work independently of each other. You won't need extra wires, modules, or links. A Firma electronic speed control provides a one-wire solution for obtaining telemetry data such as RPM, temperature, battery voltage and capacity.
Firma ESCs not only gather the data, but also send it to your transmitter in real time, instead of only storing it for after-run study. You're able to adjust settings as needed to boost performance on the go. The Firma Smart single-wire telemetry solution has been tested for quality and performance by the best brands in RC. Their verdict? Smart technology is both simpler and superior!
Field-oriented Control
The Spektrum Firma Sensored Smart ESC features a high-precision magnetic encoder and rotor position sensor that provides excellent 1 to 1 control feel when driving at any speed and at any angle. Perfectly suited for trail driving, rock crawling competitions, and rock racing setups. This advancement in sensored motor control allows the ESC to match your throttle input to the motors RPM with unmatched precision.
Intelligent Speed And Torque Control
The Spektrum Firma Sensored Smart Crawler ESC provides a closed loop control, ensuring that the ESC maintains torque and RPM levels even as driving conditions change. Giving unprecedented control when driving uphill or downhill and even when in wet or loose traction conditions. No matter the terrain, the Spektrum Firma Sensored Crawler System keeps you in complete control.
Maximum Power Efficiency Provides Longer Battery Life
When driving with the Firma Sensored Smart Crawler System, drivers are better equipped for the long trails ahead. The Spektrum Sensored Firma Smart Crawler System only uses the power it needs to match your desired throttle output, providing substantially more efficient current levels and extremely long battery life when compared with similar sensorless systems.
Pro-level Drag Brake Adjustment
The Spektrum Firma Smart Crawler System features a huge range of drag brake adjustability, allowing drivers to expertly tune their crawlers and scalers depending on their drive train and vehicle weight. Allowing up to 200% drag power, no matter the setup, the Spektrum Firma Smart Crawler System can keep your vehicle parked at nearly any incline.
Waterproof
The all-weather, waterproof design of Spektrum™ Firma™ Smart ESCs allows them to perform in nearly any terrain under almost any condition. Firma ESCs keep you going through dust, gravel, snow, and water.
One-Wire Telemetry
No need to connect multiple wires, sensors, modules, and links. With Firma™ ESCs, simple one-wire telemetry transmits a wide range of data directly to your transmitter in real time, including RPM, voltage, temperature, balance, capacity, and speed. *See compatibility chart for more information.
Smart Technology Battery Data
When used with a Spektrum™ Smart LiPo battery, your Firma™ ESC provides you with the benefit of battery telemetry that's automatically transmitted to your compatible Spektrum radio in real time. On your transmitter screen you'll be presented with helpful information such as number of cycles, battery capacity used and remaining, individual cell voltage, and more!
Multiple Programming Options
Multiple programming options are available. Using the Smart Firma™ ESC Programming Box, you can easily change settings on the trail to suit driving conditions. An easy-to-use Smart Link USB Updating and PC Programmer app is also available. And for those with a Text Gen capable transmitters, programming and adjustment of ESC settings can be performed, right from your Spektrum transmitter, with no additional modules or wires needed!
● 스로틀을 올렸을 때 모터가 원활하게 회전하지 않을 경우 (드르륵 거리며 돌지 않을 때) 이는 코깅(Cogging) 현상이 일어나고 있는 것입니다. 코깅 현상이 일어나면 빨리 스로틀을 완전히 내려서 더이상 변속기가 모터를 돌리게끔 시도하지 않도록 하십시오. 코깅 현상이 일어나고 있는데도 스로틀을 빨리 내리지 않을 경우, 변속기에서 모터쪽으로 전류가 제대로 흐르지 못해 변속기에 과부하가 일어나고, 곧 변속기가 손상될 수 있습니다.
위의 문제로 인한 변속기 손상은 소비자 과실이며, 초기 불량으로 처리되지 않습니다.
코깅 현상의 원인과 해결 방법
코깅 현상은 변속기와 모터를 연결하는 3가닥의 전선 중 1개 이상에서 전기가 제대로 흐르지 못할 때 일어납니다.
따라서 전기만 제대로 흘러 준다면 쉽게 해결할 수 있습니다.
아래의 순서대로 문제가 있는 부분을 찾아 보십시오.
1. 모터↔변속기 연결 커넥터 : 가장 자주 문제가 발생하는 부분입니다. 커넥터 납땜 불량, 커넥터 자체 접점 불량이 원인일 수 있습니다. 커넥터를 다시 납땜하거나, 다른 커넥터로 변경해서 납땜하거나, 커넥터 없이 전선을 직접 납땜해 보십시오.
2. 모터선 : 중간에 끊어진 부분이 없는지 점검합니다.
3. 변속기선 : 중간에 끊어진 부분이 없는지 점검합니다.
4. 모터선 (시작부분) : 모터선이 시작하는 부분은 아주 얇은 모터 코일이 모터선에 납땜이 되어 있습니다. 이 부분에 힘을 가하거나, 또는 접었다 폈다 반복하는 등 무리를 주게 되면 납땜이 떨어지거나 아예 절단될 수 있습니다. 단순히 납땜이 떨어진 경우 다시 용접하시고, 아예 절단된 경우 복구가 어렵습니다.
5. 모터 내부 코일 : 1~4번까지 점검해도 아무 문제가 없을 경우, 일단 변속기를 다른 제품으로 교체해 보십시오. 다른 변속기를 사용해도 똑같이 코깅 현상이 일어난다면 모터 내부 코일이 끊어진 것이므로 모터를 교체하십시오.
