Operation principle: when combined type motor of the present invention during as generator operation, in order to keep the constant of generator voltage, can be when load or rotation speed change, regulate the exciting current of claw-pole motor part, change the output voltage of claw-pole motor, thereby change the total output voltage of generator, reach the purpose of stable electric generation set end voltage.Because what two cover stator winding adopted is the version of series connection, the terminal voltage of generator is the output voltage sum of the output voltage and the claw-pole motor of magneto.When the output voltage of generator during less than rated voltage, forward increases the exciting current of claw-pole motor, thereby the output voltage that increases claw-pole motor reaches the purpose that increases terminal voltage; When output voltage is rated voltage, only need magneto to work, claw-pole motor need not be exerted oneself, and at this moment just can disconnect the stator winding of claw-pole motor; When output voltage is higher than rated voltage, oppositely increase the exciting current of claw-pole motor, make negative magnitude of voltage of claw-pole motor output, offset the part output voltage of magneto, thereby reach the purpose that reduces terminal voltage.
When motor moves as motor, in order to reach the desired torque of system, when using the permanent magnet motor Frequency Conversion and Speed Regulation Technique, regulate the output torque of claw-pole motor, thereby regulate the output torque of whole motor.The same with generator, what two parts stator winding adopted is the version of series connection.The output torque of combined motor is respectively magneto and claw-pole motor output torque sum, can realize adjusting to whole motor torque by the torque of regulating claw-pole motor.When low cruise,, magneto is adopted i for obtaining bigger torque
d=0 controls, and increases the torque of magneto, regulates the exciting current of claw-pole motor simultaneously, and its forward is increased to maximum, and the output torque of claw-pole motor has just reached maximum, thereby makes the synthetic torque of whole motor reach maximum.Along with the rising of rotating speed, reduce the exciting current of claw-pole motor, the output torque also reduces thereupon.During rated speed, the exciting current of claw-pole motor is zero, and can disconnect the stator winding of claw-pole motor this moment, and the output torque is the magneto torque.When speed increases again, magneto is adopted weak magnetic control system, regulate i
d, i
qWhen reducing the torque of magneto generation, increase the exciting current of claw-pole motor in the other direction, make negative torque value of its output, thereby offset the part value of magneto output torque, further reduce the output torque of whole motor, little torque output when realizing high speed, same effect when reaching with weak magnetism speed expansion.Can make by adjusting claw-pole motor output torque whole motor the output torque value variable quantity rated value positive and negative 1/3rd between regulate, realized the adjusting of wide speed range internal torque so easily, made system have good torque-speed characteristic.
