Objective and fair explanation of advantages and disadvantages of linear motor. About the pros and cons of this topic, Xiao Bian has always remembered a joke, this will be taken out to share with everyone, let everyone together "happy moment. ". 

     A: What are your strengths? My advantage is that I have no disadvantage. A: What are your shortcomings? My disadvantage is that too many advantages... 

     of course, the above is purely funny joke, is the so-called "non-saints, to err is human" , there is no perfect person, of course, there is no perfect thing. 

     Take the linear motor, although its many advantages gradually replace the traditional ball screw has been vigorously adopted, but it also has its own limitations, this issue, small series fair to explain the advantages and disadvantages of linear motor. 

     Advantages of Linear Motor 

     1.  simple structure. Compared with the traditional ball screw, the linear motor saves the middle transmission link, so the structure is simpler. 

     2. Exercise efficiently. There is a gap between the air cushion and the magnetic cushion of the linear motor, when the motor is in motion, there will be no mechanical contact, no friction and noise, and the damage to the parts is less, so it has higher working efficiency and can realize the high-speed linear motion. 

     3. Easy to adjust and control. LINEAR motor can adjust voltage, frequency, change materials and so on, to achieve different working rate, to meet the low-speed movement. 

     4. You can go on and on. In the guide rail through the series of linear motor, you can continue to extend the length of its travel. 

     Disadvantages of Linear Motor 

     1. Starting thrust is easily affected by voltage fluctuation. In the case of low speed and high slip, a constant starting thrust is often required, but when the power supply voltage fluctuates, the starting thrust changes greatly, so the power supply voltage needs to be stable. 

     2. The feed is complex. For the linear motor with moving primary, the feed is more complex when the speed is higher or the stroke is longer. 

     3. Heat loss is difficult. The heat dissipation condition of the tubular linear motor is worse than that of the flat linear motor, which limits the electrical parameters allowed by the motor and limits the thrust of the motor, so the cylindrical linear motor is not suitable for high-power motors. 

     In the purchase of linear motor, we should pay attention to the purchase channel, in order to ensure the quality of equipment, please purchase from formal manufacturers, such as our Kunshan Tongmao Electronics Co. , Ltd. , linear motor development, production and sales of more than 10 years of history, european and American technical standards and processing technology.
