When consulting with customers on a daily basis, we find that many customers confuse the frequency and bandwidth of linear motors. In this, we will briefly introduce the difference and connection between the two. 

      Frequency of Linear Motor Movement The frequency of movement refers to the number of cycles of completed by the linear motor in a unit of time. It is usually measured in Hertz (Hz). For example, 10 Hz means that 10 times reciprocating motion are completed in 1 second, and the frequency of movement of the linear motor depends on its structural design, the frequency of the driving current, and the damping of the system. 

      Bandwidth of Linear Motor The bandwidth refers to the frequency range that the system can effectively respond to. For a linear motor, the usually refers to the frequency range in which the motor can maintain stable output from low frequency to high frequency. The unit of bandwidth is also Hertz (Hz). 

      The Relationship between Movement Frequency and Bandwidth Frequency Response: The bandwidth of the linear motor determines the frequency range of the movement that it can respond to. If movement frequency is within the bandwidth, the motor can effectively generate motion; if the movement frequency exceeds the bandwidth, the motor's response will be weakened, and even it may not able to generate effective motion. 

    System Design: The bandwidth of the linear motor is affected by its mechanical structure, electromagnetic characteristics, and control system. These factors to be considered during design to ensure that the motor has sufficient bandwidth in the required movement frequency range. 

    Control Signal: The frequency of the current signal driving the linear should be within its bandwidth to ensure that the motor can accurately respond to the control signal. If the frequency of the current signal is too high or too low, the motion performance of motor will be affected.
