Take these dry goods, how to distinguish the linear motor(linear motor) good or bad. With the increasing rise of our industry, many traditional instruments have been unable to meet the growing demand for production, and there has been no market for them. Gradually replaced by linear Motors(linear Motors), but everything has three or six, and all types of linear Motors(linear Motors) in the market are mixed, mixed, and the prices are very different, making buyers unable to start. The following small editor says how to determine the good or bad of a linear motor(linear motor).
Type of linear motor(linear motor): Essentially classified, linear motor(linear motor) is divided into iron core and no iron core. There is an iron core linear motor(linear motor), the stator upper magnetic steel is fixed on the bottom base, and the upper part is a motor composed of iron core and copper wire. Due to the dual action of iron core cutting magnetic lines and stator magnetic steel, its thrust and moment of inertia are too large, and the speed and acceleration are low. It is suitable for use in low-speed heavy loading and high thrust conditions.
The iron-free linear motor(linear motor), also known as the U-shaped slot motor, consists of a stator high-density magnetic steel, and a stator inner ring. Because the magnetic steel is evenly arranged, the magnetic flux is large, and there is no iron loss, the inertia is small, and the response is fast. High speed, high acceleration, Suitable for high speed reciprocating movement and high acceleration movement.
How to judge a linear motor(linear motor): 1. Observe the plane and roughness of the stator. The more flat the stator, the smoother the surface, the better the motor performance! The stator plane degree is the cornerstone of the entire platform. The plane degree and pitch of the platform directly affect the absolute positioning accuracy of the platform and the smoothness of the acceleration curve during motion. A good linear motor(linear motor) should have a plane degree of less than 1U. In excess of this value its price is greatly reduced, whether it is domestic or foreign, the plane degree is good or bad, the machine processing cost difference is dozens of times! Observe whether the width of individual magnetic steel is consistent with the color of magnetic steel and the level of all magnetic steel. The narrower the width of a single magnetic steel, the better the motor performance. The narrower the magnetic steel cover, the more uniform the intensity of overlapping magnetic fields, the more stable the motor operation. However, the narrower the magnetic steel, the more difficult it is to process, the easier it is to paste uneven, and the greater the cost difference.
The silver color of magnetic steel, the better the motor performance! The color of magnetic steel affects the material of magnetic steel itself. The higher the magnetic flux, the brighter the color of the magnetic steel itself, the fuller the color, and the darker the color of the poor magnetic steel, the worse the color and reflection. 3 Observation is thicker than motility. The thinner the kinematics, the better the motor performance! The more uniform the arrangement of the internal coils, the more stable the motor is running. It can be said that each company's kinematics structure is almost the same, which is also the secret and core of each company.
