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 goog 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 goog 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 motos is of rolling bearing and oilfilling without stopping motors structure.
Structure features
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 as1.8 times as the rated rotating moment. Itwill 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.
Products performance
1. The allowable ambient temperature for the operation of the motors is -30~ +40 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, motors can
work for a long period without outer
smoothing reactor.
Working conditions
Series ZFQZ 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 reversal rotation and start stop in high frequency in a bad working circumstance . The motors are goodoverloading.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
IEC34-13Technical Criterions of Auxiliary Machine and Hoisting and MetallurgyOutline 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.
