Wire and cable, electrical should know some common sense


Stator And Rotor ac induction motor parts 
Specifications
1. 20 years manufacturing experience 
2. competitive price,high quality 

3. Material: silicon steel 
Wall switch off the ground should be www.facebook.com/guohong.trading 1.3 meters, 0.3 mira line wall socket switch should be 2-3 m above the floor. Electricity meter from the ground should be 1.4-1.8 meters into the line the ground should be 2.7 meters from the diesel engine path, a, secondary roads, electric drive, the main river, low voltage circuit, special cableway, etc, should not have joint. Ming with plastic sheath line is mainly used for indoor installation, may not be directly into the plaster layer in the dark with laying. Wire wear tube general requirements tube total cross- sectional area of the wire (including insulation) is not more than 40% of electric water pump line pipe inner sectional area. Wire tube shall have joint, joint should be within the junction box; Different power supply circuit and voltage loop, as spare circuit, line work lighting 3 phase induction motor and emergency lighting shall be installed in the same tube. Pipe for steel pipe (tube), the same communication circuit wiring must wear the same tube, do not allow a wire through a steel tube.

Specifications
1. Specifications1.3-phase asynchronous motors 
2. IEC standard 
3. OEM 
4. Voltage:50HZ &60HZ;380V&415V 

5.Protection class: IP54 
A root canal on the conductor shall not exceed small diesel engine eight. Steel (iron) for pipe, the pipe must be reliable grounding. Pipe for steel pipe (tube), the line must add plastic on alternator generator both ends of pipe. Wire wear tube length of more than 30 meters (half hard tube) which should be installed between the junction box. Wire wear tube length more than 40 meters (iron pipe) which should be installed between the junction box. single phase induction motor Wire wear tube, there is a curved line pipe length no more than 20 meters. Which should be installed between the junction box. Wire wear tube, there are two curved line pipe length is not more than 15 meters. Which should be installed between the junction box. Wire wear tube, there are three bending tube length is not more than 8 meters. Which should be www.dongfeng- motor.com installed between the junction box. When using polyphase power supply, wire of the same building insulation color selection should be consistent, namely protect wire (PE) should be green/yellow double-color wire, neutral wire (N) line for the light blue; Line L1 - yellow, L2 - green, L3 - red. Single-phase power supply switch line is red, after the switch general USES white or yellow. magnetic generator Joint position of the wire should not be in the insulator fixed place, joint location away from the wires should be above 0.5 meters, hampering binding wire and broken.

DBJ08-20-98 household electric equipment should meet the following standard

 Cast iron ac induction electric fan motor parts 
Specifications
1. 20 years manufacturing experience 
2. competitive price,high quality 
3. Type: iron body of AC electric motor
15, less circuit more series. This 3 phase induction motor kind of method is very old, and the main characteristic is extremely province line, the disadvantage is that the wire load is too large, aging serious, one problem, all the problems. So, now this way of wiring has been eliminated, basic still in use in www.dongfeng-motor.com the countryside. More than 16, circuit wiring according to room. This way is electric water pump also now in use, but not the mainstream, main characteristic is a province line and the worker, the disadvantage is that a room has a high-power electrical appliances, small power electrical appliances, open with must be a big match, out of the question has certain security hidden danger. Main use for a long time aging faster. More than 17, circuit wiring according to the acmotor2.blogspot.com function.

This way is the mainstream of the wiring way on the market at present. Benefits diesel generator set a lot, of course, weakness is more yarn florist. 18, no allocation of disorderly cloth and dominated by multi loop according to the function diesel generator set of wiring, combined with the specific situation, does not violate the principle of flexible processing. The former are not enough, the latter is possible. So, we can use the above two formulas and decoration function distribution and convenience and safety, to see how domestic outfit matching is better. (for the electric wire load, my calculation principle is 1.5 times diesel engine more alternator generator than the total load is ok, too much ac motor is a waste, even if you have money, wasting precious national resources are wrong, ha ha...)

Stepper motor and ac servo motor performance comparison different running performance

AC Induction Plastic motor fan 
Specifications
1. Customised 
2. good quality 

3. 20 years manufacturing experience 
Stepper motor control for the open loop control, single phase motor start frequency is too high or too much load step easy appear lost or blocked, stops frequently occur high speed overshoot phenomenon, so as to ensure the control accuracy, should handle the ascending and descending speed acmotor2.blogspot.com problem. Ac servo single squirrel cage induction motor phase motor drive electric water pump system for closed-loop control, the actuator can small synchronous generator diesel engine be three phase induction motor directly to the 3 phase induction motor motor encoder feedback signal sampling, internal position loop and speed loop, ac induction motor general won't electric generator appear step motor lose step or overshoot phenomenon, more reliable control performance.
