Currently a small three phase motor challenge for many embedded system is running in a very short period of time to perform a series of important tasks at the same time. Direct memory access (DMA) module provides the solution is to make through hardware control data using interrupt source to automatically read single phase motor price or write. However, this scheme before the arrival of waiting for next interruption usually DMA to execute commands to read or write, only its function will be restricted. stator In embedded systems, the interrupt events often involved in other logical processing. Before moving the data to the final destination, for example, to intervene to confirm or to modify the Electric motor data signal processing. Thus, a backed by DMA interrupt often can only make part of generator price the work, the CPU will be set aside part of the main program to complete these tasks by interrupt. In this way, the interrupt processing makes the CPU performance in other functions of the diminished. In addition, must have the accurate time single phase 3 hp motor requirements to ensure the normal operation of the system at the same time to deal with complex applications.

XGATE application is in order to improve the electric motor parts response speed and reduce the CPU interrupt of the load, through the interrupt execution at the same time with the CPU in order to achieve the purpose of the operation. Then the XGATE can be used to do? motor rotor XGATE is positioned in the fast interrupt processing, can reduce the load on the CPU interrupt processing. Most embedded applications require many interrupt program to deal with simple function, the processor often perform tasks with high rate. These are usually associated with interface functions, such as the speed controller to control feedback and communicate with other parts of the system. XGATE is used to help CPU of these events. XGATE of an important characteristic is its setting although very simple, but allow develop complex applications. XGATE DMA controller is better than that of a smart, because it provides the ability of a complex I/O processing. When the XGATE use with CPU12X nuclear, there are some limitations to consider, but will not affect XGATE the designed function. XGATE provides applications with a higher level of interruption, through Shared some service programs and processes to shorten the work of CPU time.

The choice of intermediate relay

Intermediate relay mainly plays a role of signal transmission and transformation in the circuit, it can implement multiple control, and small power control signal can be converted to the large capacity of contact action, to drive the www.dongfeng-motor.com electric actuators. Intermediate relay contacts, can expand other electrical control function. Choose intermediate relay, mainly on the basis of the control circuit voltage grade, should also consider the number of contact, type and capacity to meet the requirements of the control circuit. Commonly used in machine tool in the rotor and stator middle of the relay type has diesel generator set two kinds of JZ7 series, JZ8 series. JZ8 for ac/dc relay. The selection of time relay. Time relay is one of the line is commonly used in electrical machine control. Its types are: electromagnetic, air damping type, electric and electronic etc. Application more is the air damping type time relay. small diesel engine alternator generator Its characteristic is reliable, simple structure, time delay setting range wider (up to 0.4 ~ 180 s). The models have JS7 - A, JS16 series. Tao, the choice of a time relay mainly considering control system circuit electric generator delay contact way of the delay, delay range and the www.facebook.com/guohong.trading generator number of the instantaneous contact, but also pay attention ac motors to the coil voltage grade can meet the requirements of control circuit.

The role of voltage transformer and current transformer

The high voltage proportional relationship to transform the 100 v or lower level standard secondary voltage, for the use of protection, measurement and instrumentation. At the same time, the use of voltage transformer can be high voltage and electrical isolation. Although also be in accordance with the working principle of electromagnetic induction voltage transformer equipment, but its electromagnetic structure compared with the current transformer is just the opposite. Voltage transformer secondary circuit is high impedance circuit, the size of the secondary current is decided by the impedance of the loop. Secondary load impedance, small secondary current increase, makes a in a component of current automatically to meet electromagnetic balance of the relationship between the primary and secondary side. A voltage transformer is, as it were, structure and using a limited form of special transformer. Electromagnetic single phase motor current transformer is widely used in power system (hereinafter referred to as "current transformer"), its working principle is similar to the transformer. 

The principle of current transformer wiring, as shown on the left. The characteristics of the current transformer is: (1) a coil in series in the circuit, and as a result, the number of turns in a coil current depends on the load current of the circuit under test. And has nothing to do with the secondary current; (2) current transformer secondary coil of the current meter and relay to the coil impedance is 220v 1.5kw ac motor very small, so under normal circumstances, current transformer run in to a short-circuit condition. The ratio of the current transformer primary and secondary rated current, called the rated mutual acmotortrading.blogspot.com inductance of the current transformer ratio: kn = I1n/I2n Because of one coil rated current I1n standardization, secondary coil rated current I2n unification of 5 (1 or 0.5), so the rated mutual inductance current transformer ratio have also been standardized. Kn can be approximately expressed as transformer primary and secondary winding turn ratio, namely the kn material kn = N1 N2 / type of N1, N2, for one, two coil number of turns.

Simplified Water pump formula: (1) the motor rated current (A) : "double motor power", namely "A kw two amps. Usually refers to the commonly used 380 at www.facebook.com/guohong.trading about 3 phase induction motor 0.8 v, ac synchronous generator the power factor of three-phase asynchronous motor, "kw auto spare parts number plus one times the rated current of the squirrel cage induction motor motor. (2) empirical formula: the motor rated three phase induction motor current (A) = motor capacity (kW) x 2). The simplified formula and 3 phase induction motor empirical formula is the use of the result is consistent, calculate the rated current and motor nameplate was very close to the actual current values, conforms to the practical requirements, such as a Y132S1-2, magnetic generator 10 kW motor, using the simplified formula or empirical formulas calculate its rated current: 10 x 2 = 20 a.

1, the circuit breaker to choose 3 times of the rated current is correct! Because the starting current is in an instant. Circuit breaker due to inertia too late response! 2, the Angle of operation and starting current ratio, Angle is 1.73 times of stars! Marked on the Single phase motor motor nameplate! The motor starting current why so big? In the next work, meet a problem: a current rating of 12 a submersible pump, starting current biggest reached 227 a, the wholesalemotor.blogspot.com result will be a upstream switch thermomagnetic tripping protection action. Insulation resistance, no problem, we check the motor is started normally (general starting current in 200 when A normal boot), motor running current of 9.2 A. General starting current is about 4 ~ 7 times the rated current, what reason can make the starting current is so large, whether related to pump lobe jamming? Supplementary question. You refers to the phase insulation of the cable? Haven't test, the motor rated voltage is 380 v, no star 3 phase induction motor triangle the circuit, because running current is normal, so wrong into triangular possibility is not big, besides the two motor starting current is the same, at the same time, the possibility of the same fault is small. In addition, permanent magnet motor also want to ask, two motors at the same time, the starting current will stack?
