The eight advantages of linear motors

time£º2017/7/24  click£º7311

¡¡¡¡In the past, usually with a rotating motor through the crank connecting rod or worm gear and other transmission mechanism to get linear motion. This form of transmission tends to bring complex structures such as complex structure, heavy weight, large volume, poor engagement accuracy and unreliable work. So people began to develop a new type of motor to replace the traditional motor, so the linear motor came into being. Linear motors have a unique advantage, so that it is vigorously developed. Its advantages are:
¡¡¡¡First, the structure is simple. Linear motors do not need to go through the intermediate conversion mechanism and produce linear motion, which greatly simplifies the structure, reduces the motion inertia, greatly improves the dynamic response performance and positioning accuracy. It also improves the reliability, saves the cost and makes the manufacture and maintenance easier. Its first class can directly become part of the organization, this unique combination makes this advantage further reflected.
¡¡¡¡Second, high acceleration. This is a significant advantage of linear motor drive, compared to other leadscrews, timing belts and rack and pinion drives.
¡¡¡¡Third, suitable for high-speed linear motion. Because there is no centrifugal force constraints, ordinary materials can also achieve a higher speed. And if the initial, sub-level with air cushion or magnetic pad to save the gap, no mechanical contact movement, so the movement part of the friction and noise. In this way, the transmission parts are not worn, can greatly reduce the mechanical loss, to avoid the streamers, cables, gears and pulleys caused by noise, thereby enhancing the overall efficiency.
¡¡¡¡Fourth, the primary winding utilization is high. In the tubular linear induction motor, the primary winding is cake type, there is no end winding, so the winding utilization is high.
¡¡¡¡Fifth, no lateral edge effect. The lateral effect is the weakening of the magnetic field at the boundary due to the lateral breaking, and the cylindrical linear motor is not broken in the transverse direction, so the magnetic field is evenly distributed along the circumference.
¡¡¡¡Sixth, easy to overcome the problem of unilateral magnetic tension. Radial tension to offset each other, there is no single-sided magnetic tension problem.
¡¡¡¡Seventh, easy to adjust and control. By adjusting the voltage or frequency, or the replacement of secondary materials, you can get a different speed, electromagnetic thrust, suitable for low-speed reciprocating operation.
¡¡¡¡Eighth, strong adaptability. The primary iron core of the linear motor can be sealed with epoxy resin as a whole, with good corrosion resistance and moisture resistance, and it can be used in the environment of moisture, dust and harmful gas. It can also be designed into a variety of structural forms to meet different situations need.
¡¡¡¡Linear motor variety, rotating motor with the variety, linear motor almost all have the corresponding varieties. At the same time can save a lot of intermediate drive mechanism to speed up the system to reflect the speed and improve system accuracy, so get a wide range of applications. Linear motor through the direct drive of the load, you can achieve from high to low speed and other different ranges of high-precision position positioning control. With the unique advantages of linear motor, linear motor in the future will vigorously develop. Want to know more about linear motors, welcome to visit the official website with the Tongmao
