There are significant differences between 8LS synchronous motors and three-phase asynchronous motors in several ways.

First of all, from the perspective of working principle, the working principle of three-phase asynchronous

motors is based on the law of electromagnetic induction. The core structure consists of a stator and a rotor.

When alternating current passes through the three-phase winding on the stator, it generates a rotating magnetic

field in the stator, and the rotor generates an induced electromotive force by sensing this magnetic field, which

drives the rotor to rotate. The synchronous motor works by rotating the rotor of the motor synchronously with

the external magnetic field, which requires a rotating magnetic field to be provided externally, and makes the rotor rotate through synchronous movement.

Secondly, in terms of performance characteristics, the three-phase asynchronous motor has the characteristics

of large starting torque, simple structure, low cost, etc., and is widely used in the industrial field for driving

various equipment and machinery. However, due to the slip phenomenon of asynchronous motors, their speed

is not exactly equal to the speed of the rotating magnetic field, so their efficiency is slightly lower than that of synchronous motors.

The synchronous motor has the characteristics of stable speed and high efficiency. Its rotor rotates in sync

with the external magnetic field, so its speed is exactly equal to the speed of the rotating magnetic field. In addition,

synchronous motors can achieve accurate speed control and constant speed control, with high torque accuracy and

strong low speed and heavy load capability. The stator coil of synchronous motor generally adopts multi-pole winding, which

improves the utilization efficiency of the motor. At the same time, the mechanical structure of the synchronous motor is

relatively simple, and the size is small, which is easy to load, install, maintain and change.

In summary, 8LS synchronous motor and three-phase asynchronous motor have significant differences in working principle,

performance characteristics and application occasions. The specific choice of motor depends on the actual needs and application scenarios.
