Brushless electrical motor era is approaching
Carbon brushes as the most consumed product in electrical vehicle industry has been the main source of interest bound of electrical vehicle manufacturers and the main means the manufacturer to open a gap in the market, it also feed a large number of brushless motor manufacturers. However, with the rise of brushless DC motor, this ever glory hardware accessories industry may be will withdraw from the stage of the history.
Recently, Chen Nan who from the Shenzhen Technology Co., Ltd. receiving a lot of hardware in the loop editor interview said that compared with the brush motor, brushless motor with low noise, no dust, and no wear and tear characters, so brushless motor have become increasingly and more recognized customers.

What is stepper motor?
Stepper motor is a kind of implementing agency that transforms electrical pulses into angular displacement. It means that when the stepper driver receives a pulse signal, it will drive stepper motor to set the direction of rotation at a fixed angle (and the step angle). You can control the number of pulses to control the angular displacement, so as to achieve the purposes of accurate positioning; at the same time you can control the pulse frequency to control the motor rotation speed and acceleration, to achieve the purposes of speed control.
Stepper motor can be divided into permanent magnet (PM) brushless motor, reactive (VR) brushless motor and hybrid (HB) motor, Permanent magnet stepper motor usually is two-phase, and the torque and size are smaller. Usually the degree step angle is 7.5 or 15 degrees; however reaction step is generally three-phase.
traxxas rc car brushless motor
traxxas brushless motor is a famous rc car motor brand, traxxas motor is different from other brushless manufacturers or other relevant motor producers. It is a professional manufacturer specialized in manufacturing rc brushless motor.
Traxxas’s founded was started from a fully assembled, hobby-class R / C cars fan’s new concept ideas in 1986. The car was concentrated on all of the love-level packages, such as replacement parts, the number of jumps, and high-quality radio system components the same benefits, but it will assembly variety of body right. Traxxas proposed "ready to run" (RTR) concept to describe this new class. In the next few years, Traxxas' electric RTR models continued growth characteristics and performance.
The use of brushless DC motor
Central air conditioning is an absolute energy-hungry machine; in addition, the noise is the attention manufacturers and buyers focus on. In the April 7-9 meeting of the China Refrigeration 2011, the DC brushless motor fan coil noise characteristics are "sought after’ air-conditioning manufacturers because of its excellent energy-saving.
As the name implies, the brushless DC motor used in fan coil is brushless DC motor. Compared to ordinary AC motor, the electronic means of changing direction DC brushless motor used replace the traditional mechanical changing way, which to avoid the mechanical change in the electromagnetic interference and electromagnetic noise, so it make indoor environment more quiet and comfortable.
In addition, for the fan, the higher speed is, the greater the noise. However, brushless DC motor can achieve low-speed operation, thus further reducing the noise value.
The starting frequency of Stepper motor
Stepper motor has technical parameters: no-load starting frequency, i.e. the pulse frequency of the normal start when the stepper motor with no load, if pulse frequency is higher than this number, the motor can not start, it may occur lose steps or blocked. In the case of load, the start frequency should be lower. If you want the motor to achieve high-speed rotation, the pulse frequency should speed up the process, that means Starts frequency is lower, and then rise by a certain acceleration of the desired frequency (motor speed rises from low to high-speed). Stepper motor plays an important purpose in the era of digital manufacturing with its significant features. Along with the different development of digital technology and the stepper motor itself and improvements in technology, stepper motor will be applied in more areas. At the same time, stepper motor can be converted to DC motor and AC motor.
The difference between DC brushless motor and ordinary DC motor
Brushless DC motors have the same general principle and application characteristics with general DC motors, but and its composition is not the same. In addition to the motor itself, the former has additional circuit, the motor itself closely linked to the circuit. Many small power motors for the motor itself is one of the circuit synthesis, brushless DC motor and DC motor are the same from the appearance.
DC brushless motor itself is part of electromechanical energy conversion, in addition to the motor armature, permanent magnet two parts, it also has sensor. Motor itself is the core of DC brushless motor, it is not only related to the performance indicators, noise and vibration, reliability and service life, but also involved in manufacturing costs and product costs. Think to adopt permanent magnetic field, made DC brushless motor DC motor out of the design and structure of general tradition.
The origin of servo motor
Servo: from the meaning of .Greek word "slave". People want to make "servo organization” into a docile tool, so as to subject to the requirements of control signal. Before the signal came, the rotor is stationary; when the signal came, it immediately turns the rotor; but when the signal disappears, the rotor can be immediately stopped. Because of its "server" performance, hence the name was adopted.
Servo motors are generally divided into DC servo and AC servo. as to servo DC motors, the advantages is that it with accurate speed control, hard torque speed characteristic , simple principle, easy operation methods and cheaper price. But it also accompanies with some disadvantages, such as brush commutation, speed limits, additional resistance generated, wear particles (for clean room).
The difference between AC brush motors and AC brushless motors
Ac Brushless motor is new product, its life performance is better than AC brush motors’. But its control circuit is more complex, and the aging of the components screening requirements are more stringent. Although the motor’s life is long, but the control circuit is easy to broke. Therefore, the choice of Ac brushless motor MUST go through rigorous reliability tests to ensure quality.
In the actual production process, because brush DC motors are high-speed motor, the gear teeth is small and easy to wear, but the power is large and the climbing ability is strong. While brushless DC motor eliminates the trouble of replacing the carbon brushes in two or three years. However, it is requiring high precision during the process of brushless motor control, Moreover, brushless motor controller’s price is very expensive. In contrast, brush DC motor has more advantages than brushless motor.
Simple motor- micro motor
What is micro motor? Micro motor is a motor, after power, the rotation speed at least reach hundreds of high speed r / min, and in this case, the motor torque is very small and it can not move heavy goods, then it need to slow down the speed, Micro DC motor with gear that the whole is called micro gear DC motor. This motor can speed down to tens - a few tenths of r / min and can be adjusted freely. To give an popular example, electric razor, only needs micro-motor, it precisely requires fast speed and small torque. But for some lifting equipment such as projectors automatic lifting device, it requires small rotation and big torque, so it must choose the gear brushless motor. Therefore, micro-motor is a kind of simple lightweight class motor among motors.
