The application of linear motor has its unique, is a rotary motor can't replace.
But not any occasion to use linear motor can achieve good effect.
Therefore must first understand the principles of the application of linear motor, so as to properly use it.
Its application principle has the following several aspects:
1. Select the appropriate speed. Linear motor speed related to synchronous speed, and synchronous speed is proportional to the pole pitch. So the choice of the pole pitch range determines the speed range. Pole pitch is too small will reduce the utilization rate of slot, increase slot leakage resistance and reduce the quality factor, thus reducing the efficiency and power factor of the linear planetary gear motor. The lower limit of pole pitch usually get a 3 cm. Polar distance can not limit, but when the motor output power must be the primary iron core of the longitudinal length is limited; At the same time in order to reduce the longitudinal edge effect, the number of linear motor can't too little, so the polar distance can't be too big.
2. To have appropriate thrust. Rotating machine can adapt to a lot of thrust. Will different gearbox, rotary motor speed and torque can be different. In the case of low speed, torque can expand dozens to hundreds, so that with a small motor can drive a big load, power, of course, is conserved. Linear motor is different, it can't use gearbox change speed and thrust, so its thrust cannot expand. To get a bigger thrust, only by increasing the size of the linear motor. Sometimes it is not economic. In general, in industrial applications, the linear motor is suitable for light load.
3. To have suitable reciprocating frequency. In industrial applications, the linear motor is a reciprocating motion. In order to achieve higher productivity, requires high reciprocating frequency. This means that the linear motor to walk in a relatively short period of time the trip, on a trip, go through the process of acceleration and deceleration, which is to start and brake one at a time. Reciprocating frequency is higher, the greater the acceleration of the linear planetary gear motor, the greater the acceleration of the thrust, sometimes even more than the load thrust acceleration of the thrust. A greater increase lead to the size of the linear motor thrust, and its quality increase caused by acceleration to further improve the corresponding thrust, sometimes generate a vicious circle.
4. To have the right positioning accuracy. In many application time, running in place of the linear motor by the mechanical limit to stop moving. In order to make the small impact when in place, can be combined with mechanical cushioning electric drill speed reducer. Without mechanical limit, compare locating method is simple, before put in place by travel switch control, do reverse connect braking and braking energy of motor, and to stop when in place.
Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd., as well, confirms that consumers who want ethically produced goods do the work of looking for them.
Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd. intends to make enough profit to generate a fair return for our investors and to finance continued growth and development in electric motor suppliers.
The manufacturing industry is changing fast, so, for Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd., being able to pivot and adapt as the marketplace shifts is imperative.
