Linear motor is often described as a rotary motor is flat, and the principle of the same work. Forcer (rotor) is the use of epoxy material to compress the coil made of; magnetic rail is the magnet (usually high energy of rare earth magnet) fixed in the steel. The mover of the motor comprises a coil winding, a Holzer element circuit board, an electric heating regulator (temperature sensor monitoring temperature) and an electronic interface. In the rotary motor, the rotor and the stator need to rotate the bearing to ensure the relative motion of the air gap (gap air). In the same way, a linear motor requires a linear guide rail to keep the position of the moving child in the magnetic field generated by the magnetic field. And rotary servo motor encoder is installed on the shaft position feedback as, linear motor feedback linear position feedback device, the linear encoder, it can directly measure the load position so as to improve the position accuracy of the load.
Linear motor control and rotary motor. As brushless rotary motor, stator and no mechanical connection (brushless), unlike a rotary motor, rotate and stator position remains fixed, linear motor system can magnetic track dynamic or thrust coil move (most of the positioning system application is magnetic rail is fixed, the thrust coil). The weight of the thrust coil is smaller than that of the motor with the thrust coil. However, the need for high flexible cable and its management system. With the motor of the magnetic track, not only to bear the load, but also to bear the quality of magnetic rail, but no cable management system.
Similar mechanical and electrical principles used in linear and rotary motor. The same electromagnetic force generated in the rotating motor torque in linear motor produce linear thrust. Therefore, the use of linear motor and rotary motor with the same control and programmable configuration. The shape of the linear motor can be flat plate type and U type groove type, and tube type. Which structure is most suitable for the requirements of the actual application and working environment.
