Product Description
- Features and application of industrial dc motors
Z4, Z series industrial DC motor used polygon structure so that the using rate of the stators inner space is very high. The magnet yoke is laminated style, suitable for silicon controlled commutate power supply and it can endure pulsating current and rapid change of current (load change).Magnetic poles are fixed by precise orientation. All the motors of system are with compensate winding, so the reverse performance is very well.
The insulation class of the motor is F, using of reliable insulation structure and nonmenstruum vacuum pressure impregnated, guaranteeing the stable performance of insulation and good heat dissipation.
- Performance of industrial dc motors
1.Data listed in the technical data sheet should be employed under the following conditions:
a) Altitude above sea level maximal1,000m;
b) Cooling air temperature maximal 40oC; Cooling water temperature maximal 32oC;
c) The motor can be installed under foul situation, but the right cooling method of cooling method of cooling and defend class must be chosen. If the situation is special, need humid tropic, please negotiate.
d) The motor is suitable for 3-phase bridge style smoothing reactor, also can adopt power supply of DC generator.
e) The motor accord with GB755 The ration and performance of the rotating electrical machinery, IEC60034-1 The ration and performance of the rotating electrical machinery and JB/T9577 Technical requirements of Z series middle motor electromotor;
2. The standard rated voltage of the electromotor are 440V, 550V, 660V, 750V etc. Voltage of other classes can also be derived according specific situation, but must be negotiated when ordering.
3. The basic excitation style is separately excited, the excited voltage is 220V, Voltage of other classes can also be derived according specific situation, but must be negotiated when ordering.
4. Short time overload capacity of motor.
Motor can be divided into two kinds according to the use
First kind (A): ordinary industrial DC motor; Second kind (B): metal rolling mill industrial DC motor.
a) First kind (A) motor can endure the overload (1min) according to table 3
table 3

c)The short time overload capacity seldom used means happens infrequency or only at the urgency, the motor working exceed the continuous rated overload capacity, we suggest you adjust the instantaneous open/close device of the switch according to the short time overload capacity seldom using.
The short time overload capacity seldom constantly used means its an part of the normal working period, the motor endure the continuous rated overload capacity again and again. After working at short time overload, it must working light load to make the overload periods overload root-mean-square less than its continuous ration.
d)Second kind DC motor(B)can endure the following continuous load; Working continuous within the rated voltage and rotate speed with 115% rated power overload, the temperature is higher when at this overload, other features maybe different from working at the rated condition.
Within the rated voltage and rotate speed, after running at the rated overload, working at the 125% rated power for two hours, the temperature rise cant overrun the regulated numerical value other features maybe different from working at the rated condition.
e)Second kind DC motor(B),at the rated rotate speed, the overload can reach 2.5 times no longer than 15s only used once in a while.
5. The change rate of current
Under all rotate speed and load, the change rate of current (di/dt) that the motor can endure is 250 times rated current.
6. Libration and noise
a) the libration of the motor accords with GB10068Measurement evaluation and limits of the vibration severity of rotating electrical machines which the shaft center height is 56mm and above center standards regulation.
b) The noise of the motor accords with GB10069.3 Measurement of airborne noise emitted by rotating electrical machinery and noise limits.
7. The efficiencies listed in the data sheet are for rated output, voltage and speed, and include excitation loss.
The choice of the motors capacity
1.First kind (A): Ordinary industrial DC motor. The technical data of this kind of motor please see the technical data table. The buyer can decide the capacity, voltage, running speed and the method of cooling of the motor at the buyers option.
2. Second kind (B): Metal rolling mill DC motor. The output power of this kind of motor is about 20% lower than kind (A), the detail numerical value can be negotiated by the user and the manufacture.
3. Exclude the specification of technical data in the table. Manufacturer can derive other specification at the requirement of the user.
