Rc Motors

RC toys are nothing new to the world today. These remote control operated toys are teleported with unrestricted motion. These are often radio control devices, a cable between control and vehicle or an infrared controller. These devices mainly work with the help of brushed and brushless RC Motors. The operative basics are the RC motors. Today brushless RC motors have come with better battery technology and resulted in some major advancements in toy technology.

RC Motors (majorly brushless motors) are different from electronic speed controllers and work with different RC vehicle toys. Some to name are RC trains, RC planes and RC cars—these RC motors operation with DC electric circle. They are also known as synchronous DC motors powered by direct-current electricity via an inverter or switching power supply. This power supply produced electricity in the form of alternating current. This current is responsible for driving each phase of the motor via a closed-loop controller. As a result, the controller provides current pulses to the motor windings that control the motor’s speed and torque.

Understanding different types of brushless RC car motors

The variety of options in the market can easily confuse the newcomers in the RC world. So, being a newcomer, if you are stressed, don’t feel alone. Not every RC fan is talented enough and without explanation. Understanding the RC motors in detail is not necessary. But there are some basic differences that you must be fluent in understanding. Some of the common terms that you may have to deal with include RPM (Revolutions per minute). It measures how fast the mechanical parts spin. Next is the KV (Kilovolts) rating that measures the RPM produced per Volt of supplied electricity, assuming zero loads and resistance. With such complications, here are the differences of motors you need to know.

The fitment basics

Most of the time, you will find motors by the type of vehicle it’s going into. Meanwhile, it may match the gears. But today, it is easier than ever to fit motors into more vehicles. This is because the mounting plates, pinion gears, and even spur gears are easily available. They are available in different pitches and motor shaft sizes. But it doesn’t always mean that just because it fits and can fit in, it should be used. Rather the core concern should be the drivetrains it will be handling. In the least, you should be ready for the consequences of using way too much or the wrong size motor. Also, note that a wrong size motor will drastically affect the basic response and handling of the device.

Motors are sized up

Most of the 2WD off-road RC trucks and cars are ideal for standard 540 sizes. It also suits a two-pole brushless motor and a handful of four-pole sensor setups. Many of these high power 550 motors have 5mm pinion shafts. They require special pinion gears with this construction but are a bit heavy and overpowers for any standard 2WD setup. As the power VK and RPM calculations are complex as a beginner. So you must find a balance between the poles and the turns/KC of the motor. Hence, you can consult an expert to find a compatible option. Or look into the product description to find which motor will work fine for you. However, often there is no real direct correlation between different styles and sizes of the motor.

To sensor or not or sensor motors

Another important consideration is if you need a sensorless or sensor base ESC and motor combination. Most modern racing setups are sensor-based. They offer an infinite response to the motors even at lower RPM and varying loads. This is an important helping feature for the drivers. Simultaneously, the sensorless setups lack a response. It is an ideal choice for folks who do not hit the track or don’t have a well-groomed high traction track. Both of these types come with varying control options. Plus, these motors’ mechanical time helps fine-tune the RPM range of the motor as per your needs.

The maintenance of motor

It is important to get into the fine details of motors. And when you do that, you will find that many motors are serviceable or repairable. The winding segments or Stators, the magnet rotors, end bells and bearing are typically all replaceable. Most modern motor manufacturers offer service items on the bad back end. So no need to toss them away if any damage occurs. There are many types of motors that support swappable parts. Such motors allow you to turn a fast motor into a slower one as per your needs or demands of the game.
