The motor is commonly used in daily life, many products also need to use it, to know the electrical products directly affect the use of electrical products, so many, in the selection, we must be cautious, action only choose appropriate motor to achieve better, some people ask, what is the difference between the frequency and the the main motor frequency, frequency conversion and fixed frequency motor is used, but the difference is large, so it is necessary to frequency conversion and fixed frequency motor have a certain understanding.
What's the function of an electric motor?:
An edit motor (Motor) is a device that converts electrical energy into mechanical energy. It is through the electric coil (i.e. stator winding) and produce a rotating magnetic field acting on the rotor (such as the squirrel cage closed aluminum frame) formed magnetoelectric rotary torque. Use the power of the motor according to the different DC motor and AC motor, motor power system in most of the AC motor can be synchronous or asynchronous motor (motor rotation speed of motor stator and rotor magnetic speed keeps synchronous speed). The motor is mainly composed of stator and rotor. The direction of force acting on the conducting wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (the direction of the magnetic field). The working principle of the motor is that the magnetic field acts on the force of the current, so that the motor rotates. [1]
The difference between frequency conversion and fixed frequency motor:
1 Frequency washing machine can adjust the voltage to adjust the motor in washing and dehydrating speed, also can choose a suitable washing water, washing time, dehydration time, dehydration speed according to the type and texture of clothing. As the frequency conversion washing machine adopts the direct drive motor, the transmission parts such as the drive belt are avoided, thereby further reducing the failure rate of the washing machine and greatly reducing the noise of the motor. In addition, in the entire washing process, the application of frequency conversion technology can control the speed of the motor, not only can save energy and save electricity, but also less damage to clothes, reduce clothing winding and wear.
2, and fixed frequency washing machine once started, the motor speed will remain the same, have been turned down until you turn off. The continuous high-speed operation not only costs electricity, but also damages the clothes very much. Clothes tying often happens. Because the frequency setting washing machine program is simple, the washing process is simple and the price is lower. Compared with regular frequency washing machine, frequency conversion washing machine has higher price, but it is energy-saving and efficient. It can bring more green and healthy laundry experience to users.
3, from the washing effect, there is progress is positive. That is to say the use of inverter washing machine motor is frequency, reflected in the washing machine is the rotation speed of the roller is adjustable, such as washing your clothes less or not too dirty, you can wash with low speed, low speed of power consumption is less. Motor and washing machine using the traditional fixed speed, that is to say as long as you open the power supply to the motor is rotating at a certain speed, no matter how much you wash the clothes with the speed of course, power consumption is also fixed. So, frequency conversion is relatively power-saving.
Through the above, we believe that the difference between the frequency conversion and fixed frequency motor have a certain understanding, frequency conversion and fixed frequency motor is not the same product, whether it is the performance of all types of brand, there is a certain difference, so when the choice, according to the actual need to choose, so you know is the frequency conversion and fixed frequency motor which is suitable.
