Brushless motor, a very popular motor in recent time, because the brushless motor has the advantages of small size, large torque, strong overload capacity, stable speed, long life, communication, control, etc. It is a typical electromechanical Integrated motor. In today’s increasingly automated trend, brushless motors have inherent advantages over transmission motors, so they inevitably become popular motors nowadays. Brushless motors, like servo motors and stepper motors, can support communication protocols. At the same time, they also support the installation of encoders.
What is the role of the encoder? Simply put, it is to accurately detect the speed of the motor, or know how many revolutions the motor has made, which means that it can make accurate positioning for the operation of the motor. So what types of encoders can be installed on China Spur Planetary Gearbox Company? Let’s discuss it with everyone below.
The most common brushless motor encoder is actually the Hall encoder. Generally, there are 3 monitoring points on the rotor of the motor, one every 120°, which can easily monitor and feedback the speed. However, the accuracy is low, and it is generally suitable for users who do not require high accuracy but need to know the approximate speed. The second is an incremental encoder. This encoder is one of the most accurate encoders that can be installed in a brushless motor. The incremental encoder converts the displacement into a periodic electrical signal, and then the electrical The signal is converted into counting pulses, and the number of pulses is used to indicate the magnitude of the displacement. The main function is to monitor the speed of the brushless motor and know how many turns the motor has rotated. The advantage is that the accuracy is very high, but the cost is relatively high. The third is simple magnetic coding, the general accuracy is 1000 lines, the accuracy is not as high as the incremental type, but it is much higher than the Hall encoder, the cost is much lower than the incremental encoder, generally used in mass production equipment .
When choosing the type of brushless motor encoder, you need to choose according to your actual needs. After all, the encoder is an additional component for more precise motor control. If you do not need precise control equipment, there is no need to install an encoder. ,save costs.
