Linear motor structure
It mainly consists of three parts: stator, mover and linear support wheel. In order to ensure good electromagnetic field coupling between the stator and the mover in the stroke range, the length of the core of the stator and the mover is not equal, and the stator can be made into two forms: a short stator and a long stator. Due to the high cost and high operating cost of the long stator structure, it is rarely used. The linear motor is the same as the rotating magnetic field. The stator core is also made up of silicon steel sheets with cogging on the surface. Three-phase, two-phase or single-phase windings are embedded in the slot. The single-phase linear asynchronous motor can be made into a cover pole type or through Capacitance phase shifting.
The linear motor straightens the primary expansion of the conventional cylindrical motor, and the closed magnetic field that becomes the primary is an open magnetic field, and the stator portion of the rotating electrical machine becomes the primary of the linear motor, and the rotor portion of the rotating electrical machine becomes the secondary of the linear motor. If the primary is stationary, the secondary can move linearly along the direction of the traveling magnetic field, so that the direct drive of the linear motor of the high-speed machine can be directly fed, and the primary and secondary of the linear motor can be directly installed. On the table and bed of a high-speed machine. Since the transmission chain of this feed transmission mode is shortened to zero, it is called the "zero transmission" of the machine tool feed system.
The company focuses on the production of soldering machine motor.
