What communications protocol brushless motor support
as industrial development, dongguan inductive brushless motor, a lot of transformation and upgrading of industry is facing, and manufacturing enterprises are facing from labor-intensive into automated production, from past human to accomplish, to now fully mechanized production automation, the most prominent example is the automobile industry. I believe you have seen many online automobile production line automatic production operation, compared to the manpower to do, mechanization automation can greatly improve productivity, and increase the yield of product. In the process of automated, there is a link is crucial, is to support communication protocol. Only can support the communication protocol of the motor, arranged according to the established procedures and automatic order to finish the homework, or you can only through the manpower to switching power supply control motor operation. Currently supports communication protocol of motor mainly has three kinds: brushless motor, servo motor, stepping motor.
servo stepper motor appear very early, technology and use are very mature, but they all have their own shortcomings, servo motor with high precision, big torque, but the cost is high, the lower cost of stepper motors, but slightly lower precision, no overload capacity, low jitter, etc. Brushless motor as a new type of mechanical and electrical integration of numerical control machine, although not servo motor of high precision, but there is no problem, usually replace completely torque, overload ability, low speed performance stable, the price is basic flat with stepper motor. Brushless motor also support is the most important of communication protocol, means that automation industrial upgrading, brushless motors can also as a numerical control machine and occupy the important position of energy saving.
so what communications protocol brushless motor support? Actually the brushless motor drive and servo of stepping motor drives the same, so they support in the same communication protocol.
232 agreement, this is almost the earliest motor support communication protocol, control can achieve 1 to 1, but the slowest, usually use 23 line interface.
485 agreement, the existing of the most widely used communication protocol, unmanned aerial vehicle (uav) power system, is 1 to 1 control, speed faster, it is mainly used for PWM control, man-machine dialogue, etc. , the interface for telephone line interface.
the CAN communication, temporary civil inside the highest level of communication protocol, support for more than 1 control, fast, stable, but the cost is higher.
Ethernet communication, can be understood as we use on a computer network, and support for more than 1 control, the fastest, but due to technical reasons, generally only used for high-end development.
the above is the brushless motor support communication protocol. Through communication protocol support, can make brushless motors in automatic production capacity upgrade process on occupy the important position of brushless motor is also an important direction of the motor development in the future.
