In the age of industrial automation, robots are widely used to deal with our daily lives, making our lives smarter, better and more convenient than we can imagine. The ideal motor control system is very important to the robot. This is always a difficult thing to do when designing robotic systems. Selecting the right motor in a robot requires great care and special attention to aspects such as angular position, linear motion, arm control, etc. There are many types of motors on the market today, such as lead screw motors, stepper motors, servo motors, servomotors, electric motors, electric motors and electric motors, based on a variety of application scenarios, brushless DC gear motors are used the most in the robotics industry.
