Rated current of the knife switch, shut off by general should not be diesel engine less than the sum of each load generator price rated generator current in the circuit. If the load is the motor, we must consider whether the possible maximum short-circuit peak current in circuit in the level of the rated current of electric stability under the auto 3 phase induction motor spare parts peak current (when short circuit accident, if the knife switch can pass with a maximum short-circuit current, is not squirrel ac synchronous generator cage induction motor produced because of its huge electric effect and produce the deformation, damage or touch the knife automatically pop up phenomenon, is a short-circuit current peak is the knife switch electric stability of peak current). If you have more than, you should choose rated current a greater level of www.facebook.com/guohong.trading knife switch. Inverter maintenance testing methods. In converter maintenance process, often encounter all sorts of problems, such as peripheral circuit, parameter setting bad or mechanical failure. alternator generator If is the inverter failure, which is part of the problem, how to judge slightly is introduced here.

A: servo generator diesel engine motor can be used in water or oil droplets into the place, but it is ac synchronous generator not completely 3 phase induction motor waterproof or oil. Therefore, servo ac synchronous generator motor should not be squirrel cage induction motor placed or used in the water or oil contamination of the environment. B: if the servo motor is connected to a reduction gear, using the www.facebook.com/guohong.trading servo motor should be oil seal, in order to prevent the reduction gear magnetic generator oil into the servo alternator generator motor. C: servo motor cable don't immersed in oil or water.

Working principle of the single-phase ac motor

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.
