8LS46.R0045D000-0 synchronous motor is a commonly used AC motor, which has the characteristics of rotation and rest, electromagnetic change and mechanical movement in one, and can realize the transformation between electrical energy and mechanical energy. In steady state operation, there is a fixed relationship between the speed of the synchronous motor and the frequency of the power grid, that is, the speed of the rotor is equal to the synchronous speed, proportional to the frequency of the power grid, and inversely proportional to the pole number of the motor.

8LS46.R0045D000-0 Synchronous motor is divided into synchronous generator and synchronous motor. A synchronous generator converts mechanical energy into electrical energy, while a synchronous motor converts electrical energy into mechanical energy. In modern power plants, the synchronous generator is the main type of alternator.

The torque generation principle of 8LS46.R0045D000-0 synchronous motor is different from that of synchronous generator. The torque of synchronous motor is generated by the interaction between DC field and armature rotating field. When a synchronous motor is running, its rotor rotation speed is the same as that of the rotating magnetic field generated by the stator winding, so it is called a synchronous motor.

The speed of the synchronous motor is completely determined by the power supply frequency, so when the power supply frequency is constant, the speed of the synchronous motor is also constant, independent of the size of the load. In addition, the current of a synchronous motor is ahead of the voltage in phase, so it is a capacitive load.

In short, 8LS46.R0045D000-0 synchronous motor is an important AC motor, widely used in power system in the field of power generation, transmission and distribution.
