The characteristics and uses:
ZYZJ series DC motor is my factory based on Z4 series DC motor, according to the working characteristics of sugar mill roll driven, A special series of products in the design and manufacturing process made corresponding improvement and development.
This series of machines using polygonal stator structure, high space utilization rate, compact internal structure, and using computer aided design, so that the electrical parameter control properly, so the motor has the advantages of small volume, light weight, small rotational inertia.
Magnetic loop using a laminated structure of painting and its effective measures, so that the motor can withstand working pulsating current and current change sharply, improves the dynamic performance of motor commutation. The motor can be used three-phase bridge rectifier current, and no external flat wave reactor and long-term work.
The insulation class F with novel structure, guarantee the stable performance and good heat insulation, insulation, special treatment, so that the motor has strong moisture capacity and mechanical strength, can be used in the wet tropics.
This series motor stator plus all the compensation winding, strong overload capacity, the base speed is 2.5 times of the rated torque overload capacity, high overload capacity is 1.8 times the rated current, duration 1min.
This series motor dimensions in addition to the two foot hole axial size''B'', are in line with the international standard IEC-72.
Motor performance:
1 technical data table data should work according to the following conditions:
A．The primary cooling medium temperature. into the motor is less than 40℃;
The B. working environment should not contain gas, acid, alkaline or other insulating corrosion effect;
C. motor for continuous working system ( S1 );
D. motor armature loop and excitation loop by static rectifier power supply, also adapted by DC power supply.
2. Insulation class motor F.
3.Standard rated voltage motor 440V, 520V, 660V three, the motor can also produce other voltage levels according to the user requirements, but can be determined in consultation before.
4 motor rated speed of 1000 standard, 750, 600, 500, a total of five 400r/min. Reduce the armature voltage of constant torque speed, reduce the excitation voltage of constant power speed, speed range, see technical data sheet. At rated voltage under constant torque speed control, the minimum speed of not less than 20r/min, at this time still can ensure the steady speed.
5 the current rate of change: in all speed and load current changes, the motor can withstand di/dt=200 - 250 times the rated current / sec rate.
6 standard excitation voltage is 220V, the other excitation voltage can be negotiated. To ensure that the insulating reliability of excitation system, the excitation circuit is disconnected, the excitation winding resistance in parallel at both ends of a release of resistance, to prevent the self-induction for the excitation system of shock insulation. Standard voltage excitation, which is about six times the excitation winding resistance ( cold ). The excitation voltage is higher than the standard voltage, and then release the resistance can be less than six times, and six times greater than.
7 the motor performance conforms to the national standard GB755 " technical conditions " rotary motor, can also according to IEC standard IEC34-1 or the German national standard DIN57530 requirements.
Brief introduction of structure
1.Cooling mode motor are his cold, forced ventilation, the motor comes with a blower or radial ventilation duct. The corresponding relationship between the level of protection and cooling mode is shown in table 1. The cooling air is required, power wind pressure and fan motor are shown in table 2. The air inlet motor in the drive side of the end cover on the left (right ) side or the upper (lower).
2.Installation Motor: horizontal, foot mounting (IMB3 ), in line with the international GB977 regulations.
3 The motor can be made of the double-shaft extension or uniaxial extension. Non drive side single shaft motor can be equipped with tachogenerator, encoder, overspeed protection switches and other accessories.
4.The outlet box motor viewed from the driving end, in the frame of the motor on the right. According to the need, and can also be arranged on the frame on the left, but need to specify when ordering.
5 motor adopt non-stop refueling structure.
