introduction：Vector control time，The current is divided into excitation current and torque current，If only the excitation current is given and no torque current is given，Electric machineWill not change，But magnetic moment current is also AC current，Three phases in the motor can also form a rotating magnetic field，Why isnt the motor running，Very contradictory。 The excitation current and torque current are given under the synchronous coordinate system（synchronizationdqshaft）。Synchronous coordinate system= Rotor speed+Slip rate。If you dont torque，So the slip is zero。The rotating magnetic field rotates at the same speed as the rotor，No torque output。If the rotor doesnt turn，At this time, the rotating magnetic field generated in the motor is not non-rotating，Zero frequency。Once rotating the magnetic field and rotor different speeds，And that forms the slip rate，The rotor will have torque。merely，Now the torque current cant be zero。

introduction：Wound rotor motorIn principle, it is equivalent to an ordinary asynchronous motor，There are structural differences，So there are distributed windings on the rotor。If the winding on the rotor is shorted at the collector ring，This motor（In usage）Its just an ordinary cage asynchronous motor。 The use of winding asynchronous motors，It is generally in some occasions that require large starting torque，Like a crane（crane）。Its principle is to change the resistance of the rotor winding，To change the slip rate of the asynchronous motor，To change the torque of the motor。Its stator is directly connected to the three-phase AC power supply，The rotor windings are generally connected in series to a variable resistor with a certain resistance value。When the motor starts，The resistance value of the variable resistor is a large value，After the boot is complete，By adjusting the resistance value，Finally, the resistance value is zero。

introduction：Solenoid valve wiring diagram The solenoid valve has a closed chamber，Through holes are opened at different positions，Each hole is connected to a different tubing，In the middle of the cavity is a piston，On both sides are two electromagnets，The magnet coil on which the valve body is energized will be attracted to which side，Different drain holes are opened or closed by controlling the movement of the valve body，The oil inlet hole is always open，The hydraulic fluid goes into the different drain lines，The piston of the cylinder is then pushed by the pressure of the oil，The piston in turn drives the rod，The piston rod drives the mechanism。The following Feng Yes department Oh ah will take you to understand the solenoid valve wiring diagram。

introduction：With NdFeb（NdFeB）Represented by the emergence of new rare earth permanent magnet materials and power electronics、computer、The development of control theory，From the last century90Since the beginning of the decade, three new types of stator permanent magnet brushless motors and their drive systems have appeared，respectively： 1. 1992By American scholarsT. A. LipoProfessors proposed double salient pole permanent magnet motor（Doubly-Salient Permanent Magnet Motor），Referred to asDSPMElectric machine。 2. 1996By Romanian scholarsI. BoldeaThe magnetic flux reverse motor is proposed（Flux Reversal Machine），Short for this articleFRMElectric machine。 3. 1997By French scholarsE. HoangThe magnetic flux switching type permanent magnet motor is proposed（Flux-Switching Permanent Magnet Machine），Short for this articleFSPMElectric machine，This is also the main research of the motor type。
