Panasonic servo motor features

A servo motor refers to an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed regulating device. Speed control can be realized, and the positioning accuracy is very high. The voltage signal is converted into torque and rotational speed to drive the control object.

　　Generally speaking, there are two driving modes of Panasonic servo motors: constant voltage and constant current, and the constant voltage drive is almost eliminated, and the constant current drive is generally used at present.

Panasonic servo motor power range is large, if there is no large-scale development of functional industries, the reliability, price and quality of CNC products will not be improved. At present, China has also introduced relevant policies, emphasizing market demand-oriented, focusing on CNC terminal products, driving the development of CNC industry with the whole machine, and focusing on solving the reliability and production scale of CNC systems and related functional components. Therefore, the development of servo motor, as an important functional component of the numerical control system, will also be further promoted.

Mainly rely on the pulse to locate the servo motor, the servo motor receives 1 pulse, will rotate the angle corresponding to 1 pulse, so as to achieve displacement, this is because, the servo motor itself has the function of transmitting pulses, so the servo motor rotates an angle, will send out 1 pulse, in this way, with the pulse received by the servo motor to form an echo, or called the closed loop, in this way, every time the servo motor rotates an angle, it will send out 1 pulse, and at the same time receive 1 pulse, therefore, the angle received by the servo motor is very accurate, It can achieve precise positioning of 0.001mm.

The follow-up motor is also a brushless motor, which is divided into synchronous motor and asynchronous motor, and the synchronous motor is generally used in motion control at present, and its power range is large, and it can reach a large power. The large inertia, the maximum rotational speed is small, and it decreases rapidly with the increase of power, so it is suitable for low-speed smooth operation.

The output power of the follower motor is larger than that of the AC motor, and the servo motor can be used in the fields of spark machine, manipulator, precision machinery and so on. It can be equipped with 2500P/R high-precision standard encoder and speedometer at the same time, and can also accelerate and reduce the gearbox, so that the mechanical equipment can bring reliable accuracy and high torque. The speed is well adjusted, the volume per unit weight, the output power is the highest, larger than AC motors, and much larger than stepper motors.

Advantages of relaxing servo motor.

Speed: The speed is fast, and the general rated speed can reach 2000-3000 rpm.

Timeliness: The dynamic acceleration and deceleration of the motor corresponds to a short time, generally within tens of milliseconds.

Accuracy: Realize closed-loop control of position, speed and torque, and overcome the problem of stepper motor out-of-step.

Applicability: strong anti-overload capacity, can withstand the load of three times the rated torque, especially suitable for the occasion of instantaneous load fluctuation and fast start-up requirements.

Stability: Stable operation at low speed, no stepper motor stepping phenomenon will occur when running at low speed. Ideal for use in situations where a high-speed response is required.
