Operation mode of synchronous motor
Operation there are three main types of synchronous motors, such as generators, electric motors and power compensation operation.
Runs as a generator is the main operating mode of synchronous motor.
As the motor running is another important operating mode of synchronous motor. Synchronous motor power factor can be adjusted in speed is not required, can improve the efficiency of large synchronous motors. Small synchronous motors in variable frequency speed control system began to receive more applications.
Synchronous motor can also be connected to the power grid as a compensation. Motor without any mechanical load, by adjusting the rotor excitation power flows in power to give the necessary inductive or capacitive reactive power in order to achieve the objective of improving the power factor or regulating voltage.
Synchronous generators and other types of rotating electrical machines, from the fixed stator and rotor consists of two parts that can be rotated. Generally divided into transition and hinge-type synchronous motor synchronous motor.
Transition is the most commonly used synchronous generator, its circular uniform distribution within the stator slots of stator slot embedded with symmetrical winding arranged by law. The synchronous motor stator, also known as armature, windings and stator core, also known as armature core and armature windings.
Made of the rotor core is equipped with pairs of magnetic pole shape, winding excitation windings on the magnetic pole, Tong DC current, will motor the spread formation of polar magnetic field in the air gap, known as the excitation magnetic field (also known as the main magnetic field and rotor magnetic field).
Prime mover the rotors rotate (for input into mechanical energy), of polar excitation magnetic field rotates with the shaft and turn the cutting of the stator windings (equivalent to reverse cutting field excitation winding conductors)
