3, as people living standard rise, electric rice fort, microwave oven, air conditioner, electric kettle, electric spot squirrel cage induction motor chung person households, household electricity load is growing rapidly, 1 kw of power load is not enough, so DBJ08-20-94 household electricity load design power of 4 kw, watt-hour meter to choose 5 (20) A. Price increase of residents' income and household electrical appliances, make electric motor parts a home acmotor2.blogspot.com two air conditioners, color TV sets and squirrel cage induction motor computers in the home is not new, has prompted a surge in household electricity load again, therefore DBJ08-20-98 household small diesel engine electricity load design power increased generator to 4-8 kw by 4 kw. The Induction motor high standards had permanent magnet generator been designed by 6 kw, high standards of commercial electric generator housing and more than 130 m2 residence designed by 8 kw, watt-hour meter ac motors are all made of 10 (40) A single-phase watt-hour meter.

Withstand voltage test (puncture test) is a test electrical appliances, electrical equipment, electrical equipment, electrical wiring and electrical safety equipment such as one of the main methods of ability to withstand overvoltage. The division of frequency withstand voltage test and two kinds of dc withstand voltage test. Power frequency withstand voltage test the permanent magnet motors for sale test voltage for the participants equipment more than one times to several times the rated voltage, not less than 1000 v. The pressure time: for porcelain and liquid as the main equipment of electric motor low rpm the insulation for 1 minute, for organic solid as the main equipment of the insulation for 5 minutes, for the voltage transformer is three minutes, for oil-immersed power cable for 10 minutes. Dc withstand motor electric voltage test can be passed the test of the different voltage when the value of leakage current and leakage current - voltage characteristic curve drawing. Electrical equipment by the withstand voltage test can find a local insulation defects, be affected with damp be affected with damp and aging.

A 75 kw micro can WIN - G9 inverter commissioning the strange phenomenon Cause: a cement plant users to send a 75 kw can WIN - G9 frequency converter, the cause of the problem is, in the operation of the fire smoke in the inverter, the inverter downtime. Check, the power input circuit of the machine for three phase half controlled bridge, using the principle of controlled rectifier, on the main loop of the dc energy storage capacitor "soft power" and save the small power inverter commonly used rechargeable contactor. In fact half controlled bridge in this here is equivalent to non-contact soft blunt electricity switch. Inspection found that one of the thyristor module electrical motor 12v 1000w terminals have obvious signs of flashover arc burning, but the measurement is not short circuit. Found in the disassembly easily fixed nut landed, flashover reason seems to be a connecting screw loose, causing poor contact. The module for a combination of a diode and a one-way thyristor. And then check the control panel and inverter main circuit, without exception. The module, more than two phase half controlled bridge as the ac electric motor power input, after power on, with a small power 2.2 kW three-phase motor, feel no problem, switch to the new module after a same model, then to the site for installation.

Precaution, first will run to 5 hz frequency, frequency converter load as a fan, motor connector off first, make the motor no-load running. This trial run, got a fright! Frequency at 5 hz, no-load running current 45 a, although feel slightly larger, but consider for a possible repair, or frequency converter for motor winding parameters such as starting curve or torque compensation made adjustment caused by waiting for a reason, without notice. When up to 10 hz inverter panel shows the current and the output current is measured with clip-on table, have reached the 100 a! And the oscillation amplitude of the output current is great, but test the three-phase output voltage, about 70 v, balanced and stable. The motor cable release, electric logging on the inverter output, output frequency 10 hz, the output voltage is 70 v, 20 hz to 150 v, 35 hz to 250 v, after decreasing with frequency, to 50 hz, 400 v. In this process, the measurement of three-phase output voltage balance is very good. The inverter output of V/F curve electricalmotor1.blogspot.com accords with quadratic load torque characteristics. No problem. Output voltage balance and stability, and the output current is too large and the current volatility, obviously for the load caused by abnormal. This is lead to the conclusion of conventional judgment.

Brushless dc motor of the three-phase bridge inverter main circuit of the control mode has two kinds:. Conduction mode and three three conduction mode. Two way switch tube conduction under the law and of the three-phase winding back emf waveform is shown in figure 2. Two kinds of works, each cycle has 6 kinds of conduction state, every 60. Electrical work status change. . Conduction mode, with only two switch tube at any time and at the same time conduction. Switch tube conduction sequence: VT1, VT2 - > VT2, VT3 - > VT3, VT4 - > VT4, VT5 - > VT5, VT6 - > VT6, VT1. Each switch www.dongfeng-motor.com tube conduction, 120. Electric point of view, there are 60. Electric Angle without conduction time, never happen through fault, this way of work, also known as two-phase conduction star three-phase six ways.

Three three conduction mode refers to the three switch tube at any time and at the same time conduction, switch tube conduction order: VT1, VT2, VT3 - > VT2, VT3, VT4 - > VT3, electric fan motor VT4, VT5 - > VT4, VT5, VT6 - > VT5, VT6, VT1 - > VT6, VT1, VT2. Each switch tube conduction, 180. , the conduction time increased, and if one tube conduction and shut off with a delay, through AC synchronous lamination generator short circuit occurs, causing damage to the device. In addition to good use. Conduction way flat part of the square wave air-gap magnetic field, make the output of the motor is large, the electromagnetic torque is greater than three three conduction mode, and torque stability is good.

Ac frequency conversion compressor motor is general three-phase ac asynchronous motor, dc brushless dc permanent magnet motor is of frequency conversion compressor rotor motor. Three phase motor Frequency conversion power module is also called intelligent power transistor, referred to as "IPM, a thick film integrated encapsulation. This article focuses on the output of the ac frequency conversion air conditioning circuit, there single phase induction motor are three kinds of common frequency conversion power circuit. One kind is to use a separate IPM, as shown in figure 1, IPM 11 terminals, direct welding outside control main edition; A circuit board is made of IPM and frequency conversion circuit integration, the whole circuit in the polyester encapsulation, and control ANP gost motor main board with a communication port control, is unable to repair; One is using IPM and drive circuit or the power supply circuit of frequency conversion power template, IPM has 21 terminal, control element can be seen, can repair, and control main board have signal connection.
