CHINA FACTORY DC MOTOR FULLY ENCLOSED DIRECT-COOLED ZBL4 SERIES ,CHINA FACTORY DC MOTOR ZBL4 FOR DRIVING SCRAPER CONVEYORS,CEMENT,METALLURGY,MINING,ROLLING MILLS

一．Characteristics and uses

  ZBL4 series fully closed direct cooling type DC motor, is my factory in Z4 series of forced air-cooled motor on the development of new products. Besides its original ZBL4 series motor characteristic of small volume, light weight, large output power, fully applicable to static integration of electric current and other characteristics, but also has a closed casing, therefore particularly suitable for dust and metal scraps and other places.

 This series motor adopts the lamination machine, so the application conditions for static rectifier power supply, and can withstand current changes the whole machine cannot achieve rate, the stator adopts an octagonal structure, space utilization high, pole installation location is exact, and using computer aided design, so that the electrical parameter control properly, thus reversing the motor's performance well, the outer surface of the base with a radiating rib special, increases the effective surface area for heat dissipation motor. In order to improve the output power of the motor under the effective volume.

F insulating materials used motor. Insulation structure of novel and reliable, to ensure stable performance and good heat insulation.

Rated voltage of the motor 400 volts or 440 Volts, in three-phase full-controlled bridge rectifier power supply and no external conditions of DC smoothing reactor, long-term stable operation. Rated voltage of 160 volt motor consists of a single-phase power supply rectifier bridge, at this time is the ripple current, the motor circuit must access the DC smoothing reactor, the inductance value see technical data sheet.

Installation dimension of the series motor in addition to the two foot hole axial size " B", are in line with international standards IEC72

三．Motor performance

 

1.technical data table data should work according to the following conditions

 a. Not more than 1000 metres above sea level

b. Ambient air temperature is not more than 40 degrees Celsius

c.The working environment should not contain acid, alkali and other corrosive effect on the insulation gas

d. motor for continuous working system ( S1 )

 e:The armature circuit and the excitation circuit of E. motor by static rectifier power supply, also adapted by DC power supply

f:This series motor performance conforms to the national standard GB755-87 " rotary motor basic technical requirements " also with reference to the International Electrotechnical Commission Standard IEC34-1 or the German national standard DIN57530 requirements.  2  to derive 220V, 400V or other voltage .                                              

3  Motor speed is 3000,1500,750 rpm, a total of 4 stalls. To reduce the excitation voltage is constant power speed, speed range, see technical data sheet, reduce the armature voltage is constant torque speed. In the armature current continuous conditions, the minimum speed of 20 rpm, at this time still can maintain the rated torque, speed smooth..

 4  Standard excitation voltage of 180 volts, other excitation voltage can be negotiated  .In order to ensure that the insulating reliability of excitation system, the excitation circuit is disconnected, shall be connected in parallel at two ends of the excitation winding a release of resistance, to prevent the self-induction, in standard excitation voltage when its value is about seven times the excitation winding resistance ( cold ), excitation voltage higher than the standard value, shunt release resistance value can be less than seven times, and seven times greater than.

 5  The outlet box the motor provides a ground sign posts.

 6 technical data sheet of the efficiency value of the rated power, rated voltage and speed efficiency, it includes excitation loss

四  Brief introduction of structure

1. Protection grade of the motor is IP44

2. Cooling motor for IC0041 full closed type

3. Install motor in accordance with international GB997-81, IMB3, IMB5, IMB35, IMV1, IMV15, IMV3， IMV36

4．The motor casing surface with radiating ribs, the outlet box cover above the commutator side

 5  Non rotating motor side can be equipped with tachogenerator, encoders and other accessories
