As China gradually transitions from an extensive economy to an intensive economy, it relies on improving the quality and utilization of production factors. To achieve these two goals, it is necessary to reduce consumption and costs, as well as improve product quality.

Therefore, for the mechanical industry that requires a power source, the requirements are becoming increasingly high, and the requirements for its control system servo system will inevitably require more accurate, reliable, and easy to operate low-voltage DC servo motors to maintain the operation of the machinery, save costs, reduce energy consumption, and simplify operation.

Low voltage servo motorIt is an automatic control system that can make output control variables such as the position, direction, and state of an object follow any changes in the input target (or given value). Servo positioning mainly relies on pulses. Basically, it can be understood as the servo motor receiving a pulse will rotate the corresponding angle of the pulse, thereby achieving displacement.

Because the low-voltage servo motor itself has the function of emitting pulses, the servo motor will emit a corresponding number of pulses for each rotation angle. This corresponds to the pulses received by the low-voltage servo motor, also known as closed-loop. Therefore, the system will know how many pulses are sent to the servo motor and how many pulses are received back. This allows for precise control of the motor's rotation, achieving precise positioning up to 0.001mm.


Advantages Introduction

1. Accuracy: Achieve closed-loop control of position, speed, and torque; Overcoming the problem of stepping motor out of step;

2. Speed: Good high-speed performance, generally rated speed can reach 2000-3000 rpm;

3. Adaptability: Strong overload resistance, able to withstand three times the rated torque, especially suitable for situations where the load fluctuates instantaneously and starts quickly;

4. Stability: Stable operation at low speeds, and there will be no stepping operation phenomenon similar to a stepper motor during low speed operation. Suitable for situations with high-speed response requirements;

5. Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds;

6. Comfort response: Heat and noise are significantly reduced.

The low-voltage DC servo motor includes a stator, a rotor core, a motor shaft, a motor winding commutator, a motor winding, a speed measuring motor winding, and a speed measuring motor commutator. The rotor core is composed of silicon steel laminations and fixed on the motor shaft. Low voltage DC servo motors have excellent speed control characteristics and can achieve smooth control throughout the entire speed range, with almost no oscillations, small size, high efficiency, energy-saving, low noise, no heating, and long service life.

The characteristic of AC motors is relatively soft. When the rated torque is reached, if the load torque increases, it is easy to cause sudden stall. However, low-voltage DC servo motors have fast response, large starting torque, and the ability to provide rated torque from zero speed to rated speed. Although AC motors do not have carbon brushes and commutators, are maintenance free, sturdy, and widely used, achieving performance equivalent to low-voltage DC servo motors in terms of characteristics requires complex control techniques. Nowadays, with the rapid development of semiconductors, the switching frequency of power components is much faster, which improves the performance of driving motors.

Therefore, with the increasing speed of microprocessors and specialized chips, low-voltage DC servo motors will have greater and faster development in various domestic and foreign markets. Low voltage DC servo motors are important actuators for robots, AGV cars, electromechanical systems, and aircraft models. The low-voltage DC servo motor controller provides necessary energy and control signals for the DC servo motor. By using a microcontroller, the motion trajectory of a low-voltage DC servo motor can be controlled, achieving high-precision free control. The design of the driving circuit for low-voltage DC servo motors and their application in the operation of robotic arms reflect the high cost-effectiveness and significance of low-voltage DC servo motors.


In short, with the popularization of artificial intelligence, low-voltage DC servo motors will be widely used in more and more industries. Shenzhen Zhongling Technology is a national high-tech enterprise that focuses on research and development and sales. As a high-tech company that integrates the research and development, production, and sales of servo motors and drives, Shenzhen Zhongling Technology (www.zlingkj. com) has a strong research and development team. I believe that there will be more breakthroughs in the future.
