Q:How to implement the start-stop of three-phase ac motor with the contactor?: A master switch, red, green, two button button box, five fuse short circuit protection, 1 overheating protection, ac contactor, thermal relay according to the following diagram together.

Q:Electric curtain choice dc motor or ac motor?: Electric curtain commonly USES ac motor is the best, the ac motor is torque big, such as electric curtain of electric, electric curtain of electric curtain, shutter, Roman curtain, ceiling shade, etc. But now partial open curtain motor is involved in power failure manual function, dc motor voice is very small, adopt direct current electric control method. The performance aspect is also stable. The curtain machine should be selected according to the actual needs. Note that the quality of regular manufacturer is reliable.

Q:Single phase capacitor ac motor speed regulation why does not have corresponding frequency converter: Single-phase ac motor from principle is converted by the three-phase ac motor, is just one of the phase is generated by capacitance mobile phase 90 degrees, if meet with frequency conversion governor drive the work by the capacitance of the problem. The variable frequency governor has the input single phase 220v, the output three phase 220v variety, only choose Star/Angle 380v / 220v triphase motor will work.

Q:Why don't I have a dc 12V without a brush motor and I can connect to a third phase 12V?: If the voltage is completely same can use frequency converter to drive the brushless dc motor, brushless dc machine is three windings of the synchronous motor, they are ultimately form a rotating magnetic field, is just the difference between the open loop and closed loop.

Q:Ac servo motor can be divided into synchronous ac servo motor and induction ac servo motor: Asynchronous ac servo motor refers to ac induction motor. It has three phases and a single phase, and also has a squirrel-cage and wire-wound type, which is usually used in the three-phase induction motor. Its structure is simple, compared with the direct current motor of the same capacity, the quality is one half, and the price is only one third of the direct current motive. The drawback is that it is not economical to achieve a wide range of smooth speed adjustment and must absorb backward excitation current from the grid. This makes the power grid power factor worse. The asynchronous type ac servo motor for the squirrel cage rotor is called the asynchronous ac servo motor, which is represented by IM.

Q:What are the advantages and disadvantages of synchronous motor and asynchronous motor?: The stator winding of the n synchronous motor and asynchronous motor is the same, the main difference is the structure of the rotor. The rotor of synchronous motor has dc excitation winding, so it needs to be coupled with excitation power supply to introduce current through the slide ring. The rotor of the asynchronous motor is a short-circuit winding, which generates an electric current through the electromagnetic induction. In contrast, synchronous motor is more complicated and expensive. Use n synchronous motor is used mostly in large generator Settings. Asynchronous motors are used almost exclusively in motor situations. The synchronous motor can adjust the voltage and current phase of the input side by excitation, the power factor. The power factor of asynchronous motor is adjustable, generally between 0.75 to 0.85, so in some large factories, application of asynchronous motor is large, can be added a synchronous motor for condenser, used to adjust the plant and the power factor of power network interface.

Q:Three phase ac synchronous motor is different from three-phase ac asynchronous motor: use Synchronous motors are used mostly in large generators, while asynchronous motors are used almost exclusively in motor situations. The synchronous motor can adjust the power factor by the excitation. The power factor of asynchronous motor is adjustable, so in some large factories, application of asynchronous motor is large, can be added a synchronous motor for condenser, used to adjust the plant and the power factor of power network interface. However, due to the synchronous motor of high cost, maintenance workload is big, now commonly used capacitance compensation power factor. Synchronous machine with exciting winding and the slip ring, need the operator had a higher level to control excitation, in addition, compared with those of asynchronous machine maintenance free maintenance workload is bigger; So, as an electric motor, most current asynchronous motors are chosen.

Q:Can alternator speed improve power generation?: As long as the network is connected, the speed of the generator is synchronous with the electromagnetic system, not fast or slow. The amount of power generated is determined by the torque of the rotor. From the physical structure, the stator and rotor of the generator are completely independent and non-interference parts. Generator stator active source, produce inductive electromotive force, current and drag of the rotor, the exporting of alternating current (ac), by a prime mover (oil, gas, air, water, etc.) determines the amount of active power. Reactive power source, winding of generator rotor is direct current (dc) is introduced from the external magnetic field, under the impulsion of drag, outward flow of reactive power alternating current (ac), determined by the input of rotor dc size the size of the reactive power.

Q:Is the inductance of the stator winding of single phase ac motor constant? Does the inductance of the stator winding change when the motor turns?: The size of the coil inductance and itself by the size of the density of field lines, when the motor rotates the lines of magnetic force density was in a cyclical change, so the stator coil inductance also followed in periodically change.

Q:Three-phase ac motor star row and delta connection?: Three-phase squirrel-cage asynchronous motor adopts - delta Y step-down starting advantage: Y connection of the stator winding, the starting voltage for direct using delta connection, a third of the 1/3 of the starting current to delta connection, thus features good starting current, the circuit is simple, less investment. The drawback is that the torque is reduced to a third of the triangular method, and the torque characteristics are poor. So the line is suitable for light or no-load start. In addition, note that the consistency of the rotation direction should be noted when the y-delta joins
