Overview add Ann type motor is a kind of explosion-proof performance is lower than the flameproof and higher than that of ordinary industrial enclosed type explosion-proof motor. The basic principle of explosion-proof is under acmotor2.blogspot.com normal operation conditions won't produce arc, spark or may ignite an explosive mixture of high temperature on the motor structure of take security measures to improve the safety degree, in order to avoid in the normal and recognition of appear the phenomenon of the motor overload conditions. The category of motor with explosion-proof performance. Measures are: the electrical equipment installed in a shell, motor parts the enclosure is can withstand the internal pressure, the explosion of explosive mixture and can prevent the spread of the explosion of the internal to the electric motor 12v 500w enclosure surrounding explosive mixture structure (flameproof);

Make motor electrically charged components cannot produce enough to cause explosion danger of spark and arc or dangerous temperature, or electrically charged components on these phenomena may be produced with the explosive mixture partition, make it can't touch each other or not with explosive danger degree (increased safety, ventilation, etc.). In all kinds of explosive dangerous environment, correctly selecting and all kinds of equipment form a complete set of explosion-proof motor is very important. Is a kind of explosion-proof electric motor can 3 phase induction motor be used in inflammable and explosive factory of a motor, the runtime does not produce sparks. Explosion-proof motor is mainly used in coal mine, petroleum, petrochemical and chemical industry. In addition, in the textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other departments have also been widely used. As a major power equipment, explosion-proof electric motor is often used to drive pumps, fans, compressors and other mechanical transmission.

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.

Measuring the zener diode: we usually used regulator tube voltage value is generally greater than 1.5 V,and pointer table R x 1 k resistance is to use in the table below 1.5 V batteries,so,measured with resistance R x 1 k under voltage regulator tube like measuring diode,with full of unidirectional conductivity.But the R x 10 k file pointer motor magnet table is made of 15 v or 9 v batteries,with R x 10 k test voltage value is less than 9 v and 15 v voltage regulator tube,reverse resistance would not be up,but has a certain value,but the value is significantly higher than that of positive resistance regulator tube.So,we can preliminarily estimate the stand motor run capacitor or fall of voltage regulator tube.But,good regulator tube have a precise voltage value,amateur conditions how to assess the voltage value?

 Is not difficult,to find a pointer table is ok.Method is: put a watch at first R x 10 k file,the black,red pens and respectively in the cathode and anode voltage regulator tube,then simulate the electrical motor real working state of the voltage regulator tube,then take another watch on voltage profile V x 10 V or V x 50 V (according to the regulated value),will be red,black pens and respectively by receiving the watch just now black,red pens and,at this time to measure the voltage value is basically the voltage value of the voltage regulator tube.Said "basically",because the first block of the voltage regulator tube bias current relatively normal when using the electricalmotor1.blogspot.com offset current is a bit smaller,so the measured voltage value is slightly larger,but the basic.This method can only estimate voltage value is less than the pointer table high voltage battery voltage regulator tube.If the voltage value of the voltage regulator tube is too high,can only use plus method to measure the power of the (so,when we choose a pointer table,choose high voltage battery voltage is 15 v more applicable than 9 v).
