In the design of linear motor, in order to increase the thrust density of linear motor, linear motor has higher electric load, and temperature rise and temperature distribution are analyzed with temperature field and thermal circuit calculation software. In the winding parameter design, by adjusting the winding number and other parameters to obtain the appropriate anti-electromotive force parameters(the anti-electromotive force generated by the unit line speed), the anti-electromotive force constant is improved as far as possible under the premise of ensuring that the linear motor reaches an effective high operating speed index. In order to increase the thrust generated by the unit current, the thrust density of the linear motor is further increased. Aiming at the end force caused by the end effect of the permanent magnet linear motor, a design analysis of its reduction is made. Starting from the theory of magnetic conduction wave, the phase of magnetic conduction wave at both ends of permanent magnet linear motor is changed by the method of optimizing primary length, thus weakening the end force.
The design of the linear motor above makes the linear motor have many advantages over the mechanical system, such as very high speed and very low speed, high acceleration, almost zero dimension(no contact parts), high precision, and no empty return. To complete the linear movement, the motor does not need gears, couplers, or pulleys. It is meaningful for many applications to remove parts that reduce performance and shorten mechanical life.
Nowadays, there are few manufacturers of linear motors in China. In Jiangsu, Kunshan tongmao Electronics Co., Ltd., is a well-known linear motor manufacturer, the company's main products are linear Motors, coil motors and system integration, Since its establishment, the company has been adhering to the concept of innovation, quality, and service in conjunction with technological innovation, equipment updating research and development, design products.
The company can provide U-shaped linear motors with a large thrust of 2,600 Newtons and a continuous thrust of 750 Newtons; A linear coil motor with a large output of 5000 Newtons and a stroke of 300 mm; Can provide a large torque of 50 cattle meters, swing angle of 120 degrees swing ring motor.
