Tongmao linear motor for you to resolve - what is the linear motor

      Tongmao linear motor for you to resolve - What is the linear motor? Linear motor, also known as linear motor, linear motor, putter motor. Linear motors are often simply described as rotating motors that are flattened and operate on the same principle. The mover is made by compressing the coils together with an epoxy material, and the magnetic rail is a magnet (usually a high-energy rare earth magnet) that is fixed to the steel. In a rotating machine, the mover and the stator require a rotating bearing Support the mover to ensure the relative movement of the air gap. Similarly, linear motors require linear guides to maintain the position of the mover in the magnetic field created by the track.

      Linear motor control and rotation of the same. Like a brushless rotary motor, the mover and the stator are not mechanically connected (brushless). Unlike the rotary motor, the mover rotation and the stator position remain fixed, and the linear motor system can be a magnetic or thrust coil (mostly positioned System applications are track fixed, thrust coil moving)

    1. Types of Linear Motors: The shape of the linear motors can be flat and U-shaped, and tube type. The best suited to the practical application of the specifications and working environment.

    2. The principle of linear motor: Linear motor is a direct conversion of electrical energy into linear motion mechanical energy, without the need for any intermediate conversion mechanism of the transmission. It can be seen as a rotating motor cut radially and flattened. With the development of automatic control technology and microcomputer technology, more and more linear motor control methods are adopted. Research on linear motor control technology can basically be divided into three aspects: First, the traditional control technology, the second is the modern control technology, the third is the intelligent control technology.

   3. Linear motor applications: Linear motor is mainly used in three areas: First, used in automatic control systems, such applications are more; followed by the long-term continuous operation of the drive motor; the third is used in short, short Within a device that provides great linear motion energy.

4. Linear motor advantages:

  (1) Simple structure. Significantly simplified structure, reduced motion inertia, greatly improved dynamic response performance and positioning accuracy; also increased reliability, cost savings, manufacturing and maintenance easier

  (2) Suitable for high-speed linear motion. Very smooth speed, high acceleration, acceleration and deceleration process is short.
  (3) unlimited travel length.
  (4) high transmission strength, smooth thrust.
  (5) zero backlash and flexibility.

  (6) easy to adjust and control. By adjusting the voltage or frequency, or replace the secondary material, you can get different speed, electromagnetic thrust, suitable for low speed reciprocating operation.
  (7) zero-touch operation, no wear, low noise, brushless design, suitable for vacuum and harsh environment.
  (8) high acceleration. This is a significant advantage of linear motor drives compared to other lead screws, timing belts and rack and pinion drives.
