The working principle of ac servo motor with split-phase single-phase asynchronous motor, three phase induction motor though similar, but the rotor resistance of the former is much larger than the latter, diesel engine so compared with the single asynchronous motor, servo motor has three marked characteristics: 1, large starting torque. Due to the rotor resistance is big, the torque characteristic www.facebook.com/guohong.trading curve as shown in figure 3 in curve 1, with normal asynchronous motor torque characteristic curve, compared to 2 a significant difference between the two. It can make the critical slip S0 > 1, this not only makes the torque auto spare parts characteristic closer to linear mechanical properties, and has a large starting torque. Therefore, when the stator's a control voltage, rotor rotating immediately, which has the characteristics of starting fast, high sensitivity. 2, has a wide operating range. 3, no rotation.

The normal operation of the servo motor, as long ac synchronous generator as out of control voltage, the motor stop immediately. When servo motor loss control voltage, it is in single phase operation state, due to the rotor resistance is big, the rotation of single phase induction motor the two opposite diesel generator set directions in the stator rotating magnetic field and rotor effect produced by the two torque characteristics (T1, T2 S1 S2 curve) and synthetic torque characteristic (t-s curve) output power of the ac servo motor is 0.1 100 w. When the power supply frequency 50 hz, voltage is 36 v, 110 v, 220, 110 ac motor v; When the power supply frequency is 400 hz, the voltage have 20 v, 26 v, 36 v, 115 v, etc. Ac servo motor smooth operation, low noise. But control characteristic is nonlinear, and the rotor resistance is big, loss is big, efficiency is low, so compared with with the capacity of the dc servo motor, big volume, heavy weight, so is only applicable to 0.5 100 w small power control system.

Two phase stepper motor wiring method and the current setting question 2

So you have A stepper motor drives the output current can not be adjusted of the permanent (refers to two phase full bridge output drive, such as net friend common TA8435, TB6560 and A3977 driver chip), lamination machine how to select the stepper motor is very important, if your drive is 2 A, try choosing of two phase four wire 2 A motor (such as second-hand Japanese Oriental motor are mostly the) if you choose, the six wire motor will have to choose A nominal current as 2/0.7 = 2.9 A (about) of motor. In order to better play to the role of the drive. But if you choose the output driver is half bridge (such as SLA7062M, SLA7026 drive chip), it can single phase motor only pick up, the water pump price six wire motor drive current and motor nominal current is the same. But the permanent magnet generator drive at present very few, the efficiency is low. 

Lines to for six or eight spare parts stepping motor phase winding adopts parallel operation, can play a maximum wholesalemotor.blogspot.com output torque and diesel generator set show a good dynamic performance, six line motor is unable to connect in parallel form, actually already single phase motor in internal together, the public end of the series is the center tap. Only eight line phase coil of the motor can be used in parallel. If we can open the machine back cover, take a look at the inside connection structure, can change, make six line motor into eight line, so it can be used in parallel, but electric generator not all of the six lines of motor can be changed, only can see the attachment in the form of joint from behind the motor changes, and some motor is solder joint, the restructuring skills will be needed. I have been restructured for stepper motor, the series can also be used generator in parallel, the parallel when using phase current is 1.4 times that of the original high speed performance is greatly improved, torque is increased, too.

Electronic expansion valve is adjust the volume of evaporator for liquid according to the preset program, belongs to the electronic control mode, so called electronic expansion valve. It adapt to the development of generator set spare parts the refrigeration and electromechanical integration requirements, has the good characteristics of thermal expansion valve can't compare with, provides conditions for intelligent control of cooling system, is a very promising control energy-saving components. The primary use of electric vehicle motor electronic expansion valve thermal expansion valve and the same, variety structure, but on the performance, there are many differences between this two. From the point of view of control implementation, the motor electric electronic expansion valve by the controller, actuator and sensor 3 parts, as most of the electronic expansion valve only refers to the actuator, namely controlled drive and body, only this part wholesalemotor.blogspot.com is actually unable to complete the control functions. The core of electronic expansion valve controller hardware for the single-chip computer, such as the controller at the same time to complete the compressor and the fan frequency conversion control functions, such as generally in the form of machine level even more. Electronic expansion valve sensor usually adopts the thermocouple or heat resistance.

1 current-limiting starting: in the process of starting, limit the starting current does not exceed a certain value (Im), and then keep the output current, I < Im increased under the condition of voltage, until the rated voltage; The motor speed gradually increases, until the rated speed. Slope voltage starting 2: electric motor 12v 500w in electric vehicle motor the process of starting, the output torque of the motor with the increase of voltage, when starting to provide an initial starting voltage Us, then the output voltage from the Us started to grow in a certain slope, slope adjustable), motor accelerating. When the output voltage reaches up to Ur speed voltage, the motor is basically reach the rated speed. When the motor reaches the rated speed, make the output voltage at rated voltage. 3 starting torque control: use in overloading starting torque control, it is the starting torque of the motor from small to large linear rise.

 It has the advantage of smooth starting, flexibility is good, have better protection to drag system, its purpose is to protect the drag system, extend the service life of the drag system. 4 starting torque and kick control: at the beginning of the start stage, let the thyristor within a very short time conduction after all fall, according to the original set the value of the linear rise again, enter the starting with constant current. Starting torque and kick control and torque control starting similar is also used in overloading starting, the difference is with acmotortrading.blogspot.com a sudden jump in starting torque to overcome static torque of the motor, then smooth torque rise, shorten the start-up time. Starting: 5 voltage control the voltage control starting is used for light load starting of occasions, in guarantee starting pressure drop the maximum starting torque motor, as much as possible to shorten the start-up time, is the optimal way of light load soft starter.
