Z4 Series Large DC Motor

Z4 Series Large DC Motor

Z4 Series Big DC Motor 

Product Description
Z sequence DC motor employed polygon structure so that the utilizing fee of the stators internal area is extremely higher. The magnet yoke is laminated style, appropriate for silicon controlled commutate electrical power offer and it can endure pulsating present and fast modify of recent (load modify).Magnetic poles are mounted by exact orientation. All the motors of technique are with compensate winding, so the reverse performance is really properly.
The insulation class of the motor is F, making use of of trustworthy insulation structure and nonmenstruum vacuum stress impregnated, guaranteeing the stable overall performance of insulation and excellent warmth dissipation.

1. The regular rated voltage of the electromotor are 440V, 550V, 660V, 750V etc. Voltage of other lessons can also be derived in accordance particular circumstance, but must be negotiated when buying.
two. The basic excitation type is separately fired up, the fired up voltage is 220V, Voltage of other courses can also be derived in accordance certain scenario, but must be negotiated when ordering.
three. Quick time overload capacity of motor.
Motor can be divided into two kinds in accordance to the use
Very first type (A): common industrial DC motor 2nd type (B): steel rolling mill DC motor.
a) First variety (A) motor can endure the overload (1min) in accordance to desk 1
Table one

seldom using continuously using
one hundred 200 a hundred seventy five
two hundred one hundred sixty 150
>300 one hundred forty a hundred twenty five

b)Initial type (B) motor can endure the overload (1min) in accordance to desk two
Table two

c) The quick time overload ability rarely used implies transpires infrequency or only at the urgency, the motor doing work exceed the continuous rated overload potential, we suggest you alter the instantaneous open/shut gadget of the swap according to the limited time overload potential rarely using.
The quick time overload capacity seldom consistently used means its an portion of the regular functioning period, the motor endure the steady rated overload capacity once again and once again. Soon after working at short time overload, it should functioning light load to make the overload periods overload root-suggest-sq. less than its continuous ration.
d)Second variety DC motor(B)can endure the adhering to continuous load Working constant within the rated voltage and rotate velocity with 115% rated energy overload, the temperature is higher when at this overload, other attributes probably different from doing work at the rated situation.
Inside the rated voltage and rotate velocity, soon after operating at the rated overload, operating at the 125% rated energy for two hrs, the temperature rise cant overrun the regulated numerical benefit other functions possibly diverse from functioning at the rated situation.
e) Second variety DC motor(B),at the rated rotate speed, the overload can get to 2.5 times no more time than 15s only employed once in a while.
four. The alter charge of recent
    Under all rotate speed and load, the alter price of existing (di/dt) that   the motor can endure is 250 times rated recent.
5. Libration and sounds
a) the libration of the motor accords with GB10068Measurement analysis and limits of the vibration severity of rotating electrical equipment which the shaft heart top is 56mm and over middle expectations regulation.
b) The noise of the motor accords with GB10069.3 Measurement of airborne noise emitted by rotating electrical equipment and sound limitations.
6.working problem
a) Altitude previously mentioned sea degree maximal is1,000m
b) Cooling air temperature maximal is 40oC Cooling water temperature   maximal is 32oC
c) The motor can be put in below foul predicament, but the correct cooling   method of cooling method of cooling and protect course need to be chosen. If the situation is special, you should negotiate.
d) The motor is ideal for 3-period bridge rectfier power supply, also can undertake electricity supply of DC generator.
e) The motor accord with GB755 ”The ration and overall performance of the   rotating electrical machinery”, IEC60034-one ”The ration   
and performance of the rotating electrical machinery” and JB/T9577 ”CZPT requirements of Z series center motor electromotor”.
7.The efficiencies detailed in the info sheet are for rated output, voltage and pace, and incorporate excitation loss.

The option of the motors capability
    1.Very first sort (A): Common industrial DC motor. The specialized info of this type of motor you should see the specialized info desk. The purchaser can decide the capability, voltage, running velocity and the approach of cooling of the motor at the consumers alternative.
    2. Second variety (B): Metal rolling mill DC motor. The output electricity of this variety of motor is about 20% lower than kind (A), the element numerical value can be negotiated by the consumer and the manufacture.
    3. Exclude the specification of complex info in the table. Company can derive other specification at the need of the person..
