Large Size Z4 DC Motor for Rolling Mill

Large Size Z4 DC Motor for Rolling Mill

Z4 DC motors are widely used for steel rolling mill, copper drawbench, plastic extruder, internal mixer, small metal cutting machining tool, paper making shears, printing and dyeing, cement-making, printing, spinnin and other industries.

Product Features:

Z4 series DC motor adopts polygon structure so that the using rate of the stators inner space is very high, the Z4 series dc electric motor has advantages of small body, light weight, excellent performance, wide applications, etc. It owns features of little rotating inertia, high bearing ability to varies loading, specially suits the control systems of smoothing operation, automatic steading speed, and sensitive reaction, widely used for power source and transmission source.  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 z4 dc electric motor is F, using of reliable insulation structure and nonmenstruum vacuum pressure impregnated, guaranteeing the stable performance of insulation and good heat dissipation.

Performances:

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 40°C; Cooling water temperature maximal 32°C;

c) The DC motor for rolling mill can be installed under foul situation, but the right cooling method of cooling and defend class must be chosen. If the situation is special, need humid tropic, please negotiate.

d) The DC motor for rolling mill suitable for 3-phase bridge style smoothing reactor, also can adopt power supply of DC generator.

e) The DC motor for rolling mill complies to 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 DC motor.

a) First kind (A) motor can endure the overload (1min) according to table 1

a) First kind (A) motor can endure the overload (1min) according to table 1

b) Second kind (B) motor can endure the overload (1min) according to table 2
