Characteristics of DC brushless servo motor

Small moment of inertia, low starting voltage, and low no-load current; Abandoning the contact reversing system greatly increases the motor speed, reaching up to100 000rpmBrushless servo motors can control speed, position, torque, etc. without the need for encoders during servo control; There is no wear of the electric brush. In addition to high speed, it also has the characteristics of long service life, low noise, and no electromagnetic interference.

scope of application

DC servo motors can be applied to machines such as spark machines, robotic arms, etc. Can be configured simultaneously2500P/RHigh analytical standard encoders and speedometers can be equipped with gearboxes to provide reliable accuracy and high torque for mechanical equipment. Good speed regulation, with output power per unit weight and volume greater than that of AC motors and far exceeding that of stepper motors. The torque fluctuation of the multi-level structure is small.

main function

The servo motor is used in a closed loop. That is to say, it constantly transmits signals to the system and corrects its operation based on the signals provided by the system.

Servo motors can also be controlled by microcontrollers.

advantage

Firstly, let's take a look at the advantages of servo motors compared to other motors such as stepper motors

1Accuracy: Closed loop control of position, speed, and torque has been achieved; Overcoming the problem of stepping motor out of step;

2Speed: Good high-speed performance, generally the rated speed can reach2000～3000Turn;

3Adaptability: Strong overload resistance, able to withstand loads three times the rated torque, especially suitable for situations with instantaneous load fluctuations and fast starting requirements;

4Stable: Running smoothly at low speeds, there will be no stepping phenomenon similar to that of a stepper motor during low-speed operation. Suitable for occasions with high-speed response requirements;

5Timeliness: The dynamic response time of motor acceleration and deceleration is short, usually within a few tens of milliseconds;

6Comfort: significantly reduced heat and noise.

Simply put, it means that the ordinary motor we usually see will continue to rotate for a while due to its own inertia after power failure, and then stop. And servo motors and stepper motors stop at will and leave at will, with extremely fast response times. But there is a phenomenon of stepping out of step in the stepper motor.

There are too many application fields for servo motors. As long as there is a power source and precision requirements, servo motors are generally involved. Equipment with relatively high requirements for process accuracy, processing efficiency, and work reliability, such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, and automated production lines.

Let's analyze the meaning of each word below: 1. Hardware is different from software. From the literal meaning of "weak current" and people's usage habits, weak current mainly focuses on hardware systems. The system differs from simple connections between individual items and has complexity, integration, and integrity. Civilian use is different from intelligent management and production systems and high-tech research and development fields such as artificial intelligence that involve special fields or industries such as aerospace, power and energy, rail transit, chemical and metallurgical industries. Intelligence refers to the provision of safe, comfortable, healthy, convenient, and environmentally friendly intelligent experiences for people's work, study, production, life, and public management through information collection, transmission, control, management, and other means combined with supporting mechanical and electronic devices.
