Induction motors, also known as induction motors in Taiwan and Hong Kong, use the electromagnetic induction between the stator and the rotor to induce current in the rotor to realize the conversion of mechanical energy to electrical energy. Induction motors are also widely used. However, in a general sense, they are only used as motors, and induction motors are also a type of asynchronous motors. Since asynchronous motors are mainly induction motors, some people directly call asynchronous motors when they are defined. For induction motors or induction motors.
What is an induction motor (motor)?
No matter what kind of motor, such as geared motor or geared motor has its own characteristics, what are the excellent performance characteristics and shortcomings of induction motor?
First of all, induction motors are different from other motors in the following ways, which is why it can be widely used:
1) It is becoming more and more miniaturized, and the weight is lighter, and it is more convenient to move and transport;
2) High-speed rotation of 10,000 rpm brings strong power
3) High operating efficiency at high speed and low torque;
4) There is high torque at low speed, and the speed controllable range is wide;
5) The solid shell and body can ensure the service life of the induction motor (motor);
6) Due to the continuous progress of technology, the current production cost of induction motor is relatively low;
7) Simpler control devices are easier for ordinary people to accept;
In addition to the advantages of induction motors, are there any disadvantages? The disadvantage of the induction motor is that the power is not as good as that of other geared motors, the light load power factor is low, and the speed regulation of the speed is not as free as the speed regulation motor.
Some methods of induction motor in terms of speed control:
First, the purpose of speed control is achieved by changing the voltage of the stator.
Second, change the frequency of the stator, that is, the rotational speed.
