Nan yang DC Motor Z4 series

Nan yang DC Motor Z4 series



Z4 series DC motor is the latest product of our company, widely used for all kinds of machinery transmission is willing, such as metallurgical mill rolling, metal cutting machine tools, paper, printing, textile, printing and dyeing, cement, plastic extrusion machinery and so on.
   The dimensions of this series of motors are in accordance with IEC72 international standards in addition to the axial dimension 'B' between the two foot holes.
   This series of motor performance and technical requirements can be in accordance with the International Electrotechnical Commission standards, IEC34-1 or West Germany national standard DIN57530 requirements assessment.
   This series of motors with polygonal structure, high space utilization. Stator yoke for the laminated, practical rectifier power supply, can withstand pulsating current and current changes (load changes) of the working conditions, the magnetic pole installed with precise positioning, and thus good commutation.
   Motor insulation class for the F-class, the use of reliable insulation structure impregnation process to ensure stable insulation and good heat dissipation.
This series of motors with small size, good performance, light weight, large output power, high efficiency and high reliability characteristics, with the current international advanced level of motor teaching.
   The motor can be used three-phase full-bridge rectifier power supply and no external smoothing reactor and long-term work. A motor with a rated voltage of 160V is powered by a single-phase bridge power supply where the armature circuit must be connected to a reactor to suppress pulsating current. The inductance value is shown in the table.

Motor performance:
1. The data in the technical data sheet shall be operated according to the following conditions of use:
  a. The elevation shall not exceed 1000 m;
  b. The ambient air temperature shall not be greater than 40 ° C;
  c. The working environment shall not be acidic, alkaline or other gases which are corrosive to insulation;   E. Motor armature circuit and excitation circuit can be static rectifier power supply, but also adapted by the DC generator power supply;   f.
  Motor for the continuous working system (SI) This series of motor performance are in line with international GB755 "basic technical requirements of rotating electrical machine." 2. The rated voltage of the motor is 160V, 440V. Can also be derived according to the specific circumstances of 220V, 400V and 660V or other voltage. 3. Motor rated speed of 3000,1500,1000,750,600,500,400,300,200 r / min total of nine files. Reduce the armature voltage constant torque speed, reduce the excitation voltage for constant power speed, speed range see technical data sheet (Table 2). Constant voltage is used for constant voltage regulation below the rated voltage. The minimum speed are specified not less than 20 r / min, this time can still maintain the rated torque, smooth speed. 4. The basic excitation method of the motor is his excitation, the standard excitation voltage is 180V, and the other excitation voltage can also be negotiated. The motor allows for strong excitation, strong excitation voltage shall not exceed 500V. The excitation current must not exceed the rated excitation current during normal operation of the motor. In order to ensure the reliability of the insulation of the excitation system, when the excitation circuit is turned off, a release resistor must be connected in parallel at both ends of the field winding to prevent the self-inductance potential. At the standard field voltage, the value is about seven times the field winding resistance (cold). When the excitation voltage is higher than the standard voltage, the release resistance value can be less than seven times, otherwise more than seven times. 5. Z4-315, Z4-355, Z4-400, and Z4-450 four chassis with compensation winding. It is also possible to derive a motor with a compensating winding in both the Z4-250 and Z4-280 frame sizes. 6. The motor is provided with a grounded terminal. 7. The power values ​​in the technical data sheet are rated for power, rated voltage and speed efficiency, which includes excitation losses, excluding blower losses.

Model Description:
