Let's say the structure of the open collector output. The structure of the open collector output ac induction motor is shown stator in figure 1, the right of the triode collector what all don't electric motor low rpm pick up, so called open collector (on the left side of the triode is reverse phase, the input to "0", the output is "0"). In figure 1, when the www.dongfeng-motor.com input is "0" at left, in front of the triode by (equivalent to disconnect between collector and emitter E C), so the 5 v power supply by 1 k resistor to the right of the triode, the right of the triode conduction (i.e., the equivalent of a switch is closed); When the input is "1" at left, in front Electric motor of the triode conduction, and the transistor cut-off (switch). Figure 1 we will ac induction motor simplify to look like permanent magnet motors for sale figure 2. In figure 2 switch is controlled by the software, "1" disconnect, "0" when three phase motor closed. Obviously, you can see that when the switch is closed, output it directly, so the output level of 0. And when the switch is off, the output end dangling, namely the high impedance state. Level is unknown at this moment, if behind a resistive load (even if the light load) to the ground, then the output level by the load to the low level, so the circuit is not the output level.

Stepper motor generator price is generally not have overload ability. Ac servo motor has a strong ability of overload. Panasonic ac servo system, for example, it has the speed overload auto spare parts and torque overload capacity. The maximum torque is three times small diesel engine the rated torque, can be used to overcome inertia load acmotor2.blogspot.com at startup moments of diesel generator set inertia moment. Stepper motor diesel generator set because there is no this kind of overload capacity, in order to overcome the inertia moment when selection, often need to select a larger torque of the motor, and www.dongfeng- motor.com the machine during the normal work and don't need ac motor that big torque, there is a moment of waste phenomenon.

The startup and voltage on the www.facebook.com/guohong.trading stator winding of the motor rated voltage. Three-phase asynchronous motor direct start (a) meet the conditions of 1, capacity under the 7.5 KW motor can be used. 2, motor at starting moment caused by the power grid voltage drop is not more than 10% generator price diesel generator of the power supply voltage is normal, for not often start the motor can be up to AC motor 15%. 3, available empirical formula rough estimates whether the motor can be directly started. Advantages: the boot device is simple, the startup time is short, starting operation simple, reliable, the cost is low. Disadvantages: the motor and power grid has a certain impact (2) the step-down start. The voltage on the stator winding of the motor is started to reduce, start at the end of the rated voltage of the startup mode. Step-down starting may help reduce motor starting current, but due to the torque is directly proportional to the square of the voltage, so the step-down startup motor torque decreased is more, reason is only applicable to start no load three phase diesel generator set induction motor or light load.

N autotransformer (also called compensator) step-down start n star - triangle (Y - Δ) step-down start n extended delta start n (or reactance) step-down starting resistance. 1, autotransformer (also called compensator) step-down start wiring: (1) high pressure side of the diesel generator set autotransformer into power grid, the low voltage side connected to the motor, there single phase induction motor are several different voltage than tap to choose from. (2) features: set autotransformer change ratio of K, the original side voltage of U1, U2 = vice side voltage U1 / K, vice edge current I2 (that is, through the line current of the motor stator winding) also according to the proportion is reduced, and because of I1 = I2 / K, ac synchronous generator the power supply of the motor starting current is directly 1 / K2 times when it is started. 1 / K times due to lower voltage, torque reduced to 1 / K2 times. Autotransformer vice edge from two to three groups of tap, such as secondary voltage of primary side voltage respectively 80%, 60%, 40%. Advantages: can be according to allow the starting current and starting torque required for different tap to choose autotransformer achieve step-down start, use Y or Δ stator windings. Weakness: the equipment is big, the investment is more expensive.

To make single-phase electric function automatically spin, we can add a starter in the stator winding, starting with the main windings in space by 90 degrees, starting winding to concatenate a suitable capacitance, makes differ with approximation in the phase of the primary winding current 90 degrees, the electric motor 12v 500w so-called split-phase principle. These two differ 90 degrees of electricity flow in time into the two differ 90 degrees of winding on the space, will be produced in the space (two-phase) rotating magnetic field, under the effect of the rotating magnetic field, the rotor can be automatic starting, after starting, to speed up to a certain, with the aid of an installed on the rotor of the centrifugal switch or other automatic control device will start winding broken, only main winding work in normal working conditions. Therefore, starting winding can wholesalemotor.blogspot.com mini electric motor make short work. But there are a lot of time, starting winding is not broken, we call this kind of motor capacitor, single-phase motor to change this kind of motor, can be achieved by changing the position of the capacitor is concatenated.

In single phase motor, the rotating magnetic field generated another method called shield electrode method, electrical motor also known as single phase mask pole type motor. This made salient pole motor stator, which has two kinds of the poles and quadrupole. Each pole in a third - quarter pole face open place with full of small tank, the pole is divided into two parts, on the small part of the suit on a short circuit copper ring, like pole to cover up this part, so called cover pole type motor. Single-phase winding set in the entire history of the magnetic poles, each pole of the coil is connected in series, the connection must make its polarity, in turn, according to the N, S, N, S arrangement. When the stator winding current in the magnetic main flux, according to lenz's law, which through the short circuit copper ring main magnetic flux in the copper ring produces a 90 degrees on the phase lag of the induced current, flux on the phase of the current and lag behind the main magnetic flux, its role and the capacitor motor starting winding, motor rotation to produce a rotating magnetic field.
