The difference between a linear motor and a coil motor
time£º2017/5/8 click£º9052
Linear motors are also called linear Motors, linear Motors, linear Motors, and pushrod Motors. Commonly used linear motor types are flat linear motor, U-slot linear motor and cylindrical linear motor. The typical composition of the coil is three-phase, and there is a Hall element to achieve brushless phase change.
Linear motor
The ring motor is named after its structure similar to that of the horn. It has the characteristics of high frequency loudness and high precision. This type of motor is divided into cylindrical ring motor and swing ring motor. That is, the so-called cylindrical linear motor.
Sound Module
The mover of the coil motor is a cylindrical structure. Move along a fixed magnetic field cylinder. The magnetic path of the coil motor is similar to that of the dynamic magnetic actuator. The difference is that the coil can be copied to increase the journey. The typical coil winding is composed of three phases and uses a Hall device to achieve brushless phase switching. The thrust coil is cylindrical and moves up and down the magnetic rod. This structure is not suitable for magnetic flux leakage sensitive applications. You have to be careful to make sure your fingers don't get stuck between the magnetic rod and the attractive side.
A potential problem with the design of the coil motor is that when the stroke increases, because the motor is cylindrical and moves up and down the magnetic rod, the support point is at both ends. Ensure that the radial deviation of the magnetic rod does not cause the length of the magnet contact thrust coil to be always limited.
