Product description

Product introduction:

This asynchronous alternating current motor is a YDFW series outer rotor low noise three-phase asynchronous motor is a fully enclosed squirrel cage three-phase asynchronous motor. It can be continuously adjusted by a three-phase voltage regulator. It can be widely used in drying rooms, hospitals, hotels, shopping malls, airports, cleaning workshops, research departments, etc. together with horizontal double suction centrifugal fans.

Product features:

1. This asynchronous alternating current motor has very low noise during use, so it can provide you with a good working environment. Electromagnetic induction is the key to the rotation of this motor. The rotor suspended in the magnetic field is an electrical conductor. The magnetic field is constantly changing. The magnetic field produces a current inside the rotor. If the conductor is a ring or wire, current flows in the loop. The conductor is a solid metal and the eddy current will rotate around it.

2. The theoretical speed of the rotor in an induction motor depends on the frequency of the alternating current source and the number of coils that make up the stator, and approaches the speed of the rotating magnetic field when there is no load on the motor. In practice, the load on the motor (whether it is driving or not) also acts to slow the rotor speed. The greater the load, the greater the "slip" between the speed of the rotating magnetic field and the actual speed of the rotor.

3. The biggest advantage of this asynchronous alternating current motor is simplicity. They have only one moving part, the rotor, which makes them low cost, quiet, long lasting, and relatively fault free. In contrast, DC motor commutators and carbon brushes wear out and need to be replaced from time to time. The friction between the brush and the commutator also makes the DC motor relatively noisy.
