Z Z4 DC Motor, Suitable for Industrial Department, with 2000rpm Rotation Speed

This series motor used polygon structure so that the using rate of the stator’s inner space is vary high. The magnet yoke is laminated style,suitable for silicon controlled commutate power supply,and it can edure 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.
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 maximal40℃;COOling water temperature maximal32℃;
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 comoothing 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 electricel machinery》and JB/T9577《Technical requirements of series Zmiddle motor electromotor》;
2.The standrd 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
Frist kind (A):ordinary industrial DC motor;Second kind(B):metal rolling mill DC motor.
