Motors play an important part in lifting and running a device. They are limited to weight but high efficiency and power capacity motors can easily cover heavy weight situations. Brushless Motors are best used for quadcopters, multicopters and drones.
Choosing motors for copter projects is not an easy task, so for every selection technical specifications such as thrust, power and RPM is to be checked.
Typically, planning to prepare your own project for the first time, weight is to be considered then the thrust to lift the quadcopter. The thrust should be kept higher for proper lifting, flying and landing. According to general statistics, there should be kept twice the weight of the quadcopter.
Trust is kept perfect, too low might create difficulties to take off and too high become hard to control.
A light weight copter is more efficient and durable.
Additionally, the battery is also considered an important element for long life of quadcopter. Lithium polymer batteries are best suited for long run as they do not swell nor they heat up faster. Batteries should be charged when it reaches a minimum of 20 percent. Zero percent may lower the durability of the battery. Brushless DC motors achieved high speed of 10000 RPM or above.
Brushless DC motor architecture sounds very simple and compact. A fixed armature is present in the brushless motor around which permanent magnets rotate. Brushless DC motors are best suited as they produce high torque to weight ratio, increased reliability, more torque per watt, reduced noise, no brush required, as long life, totally eliminates ionizing sparks from the commutator plus reduce electromagnetic interference. Brushless motor commutation is easily implemented using a microcontroller, analogue hardware or digital firmware by using an FPGA. Brushless commutation has greater flexibility, speed limiting, holding torque when stationary, micro stepped operation for slow or fine motion control.
Brushless motors cover a wide range of applications in the field of electronic devices which comprise of computer hard drives, DVD / CD players, refrigeration. They are also favorable to electric vehicles such as bicycle and hybrid vehicles. Users or learners can use brushless DC motor in various quadcopter, multicopter or drones adding additional accessories for a specific function. Copters help in remodeling, transfering load, surveillance, Videography and many more.
After improving its performance, again, both the coils are energized and further improved in a manner such that it pushes the rotor and energize the coils. Therefore, it results in increasing torque and power from the motor. This great achievement is seen in this motor and takes time for other type of motors to grab.
