High precision China synchronous motor manufacturing plant, synchronous motor main operation mode is three, namely as generator, motor and compensator operation.Running as generator is the most important mode of synchronous motor.
Running as motor is another important running mode of synchronous motor.The power factor of synchronous motor can be adjusted, and the application of large synchronous motor can improve the operation efficiency in occasions where speed regulation is not required.Small synchronous motor has been widely used in variable frequency speed regulation system.
The synchronous motor can also be connected to the power grid as a synchronous compensator.At this time, the motor does not have any mechanical load, by adjusting the rotor excitation current flow to the grid to send out the required perceptual or capacitive reactive power, in order to improve the power factor of the grid or the purpose of regulating the grid voltage.
A synchronous generator, like other types of rotary motors, consists of a fixed stator and a rotatable rotor.Generally divided into rotary synchronous motor and rotary synchronous motor.
The most commonly used is the rotary synchronous generator, in which the inner circle of the stator core is evenly distributed with stator slots, and the slots are embedded with three-phase symmetric windings arranged in accordance with the law.The stator of the synchronous motor is also called the armature, and the stator core and winding are also called the armature core and armature winding.
The rotor core is equipped with a pair of magnetic poles of a certain shape. The magnetic poles are surrounded by excitation windings. When dc current is running, a polar interphase scattering magnetic field, called the excitation magnetic field (also known as the main magnetic field and the rotor magnetic field), will be formed in the air gap of the motor.
