From the moment it was born, the motor has always been the darling of human beings. It used to be that the masters carefully polished it every day, and now more engineers are trying to control it precisely.
Servo motor made the robotPeople who have seen "My Robot Girlfriend" are convinced by the robotic girlfriend who looks perfect, is hot, and has an IQ that is comparable to humans. In fact, after stripping the gorgeous appearance of the robot, there are a lot of motors and sensors inside. The smooth motion of this robot is realized by using the control technology of servo motor and microcomputer.
This aspect is attributed to microelectronics technology, power electronics technology, especially the rapid development of computing technology, and the result of further maturity of servo motor manufacturing technology.
In Japan, a robot called "Murata urchin" will ride a bicycle. It can ride on a balance beam ramp of the same size as the wheel width and will not fall even if it is stopped. Not only that, but the robot can also stop or retreat when it finds obstacles. A small partner who is still not riding a bicycle will be shocked if he sees a robot that can ride a bicycle.
There are such superb skills, mainly because the robot has a gyro sensor with posture sensing, a Bluetooth module that transmits and receives commands, an eye camera, etc. These devices are quickly transmitted to the controller after sensing the external information, and then the controller will issue The control signal drives the servo motor system to quickly adjust the posture. The servo motor system here uses the torque and force generated by various motors to directly or indirectly drive the robot body to obtain various movements of the robot.
The tram is very interesting now.Saying "Whoever has a permanent magnet traction system, whoever has the right to speak of high-speed rail." The permanent magnet traction system consists of two parts: the converter and the motor. The converter is equivalent to the heart of the train. The motor is like the muscle of the train. The motor is mainly responsible for transmitting power, completing the conversion of electric energy to mechanical energy, and driving the train to run smoothly.
In order to alleviate traffic pressure, major cities are now competing to build subways. On some new types of subways, a motor called a linear motor is used to drive. This new technology motor can be seen as the rotation of the stator and rotor of the rotating machine, respectively, on the vehicle and the track, the rotary motion of the rotor directly into a linear motion. In practical applications, the electromagnetic motor driven by the linear motor uses a flat linear induction motor with the stator side placed on the vehicle and the rotor side placed on the ground in the middle of the track. The stator and rotor interact to propel the train forward, and the train's support and guidance system still uses iron wheels.
Compared with the rotating electric machine, the linear motor vehicle cancels the transmission device, improves the impact degree of the wheel and rail, and can greatly reduce the noise level in operation. Guangzhou Metro Line 4 is driven by linear motors, which also marks the end of China's history of non-linear motor rail transit systems.
The motor industry has undergone a history of precipitation, and it can be said that the motor has been fully integrated into the blood of people's lives. With the improvement of motor quality requirements, the motor testing industry is gradually emerging. Every minute of life is good, and the work of the motor is required to be more accurate. Especially for the current servo motor, in order to ensure that it can be accurately controlled under actual dynamic conditions, the pre-test must have a dynamic test link to simulate a dynamic working condition. ZLG Zhiyuan Electronics' MPT1000 motor test system is the first The free loading engine technology can realize the free dynamic control and transient waveform recording of the system load output, fully satisfying the measurement of the transient waveform and response time of the motor control system, and is the most reliable choice for motor testing.
