     · Features and application
ZFQZ Series DC motors are developed on the basis of Z4 Series and ZZJ-800 Series DC motors. The rotating inertia of the motors is 45% and 65% of the motors of Series ZZJ-800 and ZZJ-900 respectively. The motors are suitable for direct and reversal rotation and start and stop in high frequency in a bad working circumstance. The motors are good-overloading. The max. rotating moment and the starting moment are 112% and 117% of the moments of Series ZZJ-800 and Series ZZJ-900 motors respectively. The weight of the motors is just 65% of the Series ZZJ-800 motors. The class of the motor power is in accordance with the international standard IEC34-13 Technical Criterions of Auxiliary Machine and Hoisting and Metallurgy . Outline mounting dimensions of the motors comply with IEC 72 Standard, except for the axial distance between the mounting holes (dimension B). The mounting dimension of the motors with bottom plates is able to be in compliance with the dimension of Series ZZJ-800 and Series ZZJ-900 motors. Also, the shaft extension dimension of the motors can be customized into the corresponding dimension of Series ZZJ-800 and Series ZZJ-900 motors after discussion with customers. Therefore, Series ZFQZ DC motors can substitute for Series ZZJ-800 and Series ZZJ-900 motors.
 
     · Performance

Requirements for Use

1. The allowable ambient temperature for the operation of the motors is -30C~+40C and the allowable sea level is not higher than 1000m.

2. The supplying electric source of the motors adopts rectified electric source or DC generator electric source. When adopting 3-phase, fully controllable bridge rectified electric source, the motors can work for a long period without outer smoothing reactor.

Products Specification
1. There are 2 kinds of rated voltage of motors: 220V, 440V. As required, the motors with other voltage level can be produced.
2. The mode of excitation of motors is separate excitation. The voltage of excitation is 180V or 310V. As required, the motors with other voltage level can be produced.
3. The motors running at basic speed can reach max. rotating moment regulated in the Technical Data Table. It will last 60s.
4. For the motors of rated voltage 220V, the rotating speed can reach as 2 times as the rated rotating speed through increasing the applied voltage. At this time, the allowable max. rotating moment is as 1.8 times as the rated rotating moment. It will last 15s.
5. For the motors of rated voltage 220V, the max. rotating moment is as 0.6 times as the rated rotating moment when the motors are running with low-intensity magnetic rotation regulated in the Technical Data Table. It will last 15s.
6. The electric current changing rate of the motors can reach as 200-250 times as the rated electric current changing rate. It can be discussed if >250 is required.
    7. The standard position of wire outlet box of the motors is on the right of the machine baseplate seen from the drive end. If required, it can be mounted on the left of the machine baseplate. If so, this requirement should be stated in the order.

 
     · Model explanation
 
     · Structure
1.The motor baseplate is of octagon laminated thin steel plate structure. Therefore, it has many advantages such as high utilization of stator room, tight inner structure, small rotating inertia, slight weight and suitability for supplying electricity by controllable silicon.
2. All the motors have compensating winding, which makes motors have a good ability of commutation and overload.
3. The insulating level of motors is Level F. The insulation of motors is handled by VPI. The winding has a good insulation and mechanical intensity.
4. The commutator segment is of vertical plate and integral structure. The connection with the vertical plate and armature coil adopts TIG.
5. The armature core is of skewed slot structure, which is able to decrease vibration and noise.
6. The motors are of rolling bearing and oil-filling without stopping motors structure.
 
The Motor adopt continuous working system. Other working systems can convert the data in the technical Data Table according to Table 1.

All the cooling modes of the motors are of separately-cooling and forced ventilation type. It means the motors are equipped with radial ride type air blower, duct ventilation cooler or air/water cooler. The corresponding relations between the protection level and the cooling mode are shown in Table 2. The ventilation quantity, ventilation pressure and the air blower power of the cooler are shown in Table 3. The recycling air blower power and cooling water discharge of the air/water cooler are shown in Table 4.
