Z seris motors are used for metallurgy & hoisting, available for steel rolling machine, crane, elevator and electric excavator.
Characteristic and use
This series motor used polygon structure so that the using rate of the stators 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.
Electrical machinery performance
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 GB755The ration and performance of the rotating electrical machineryIEC60034-1 The ration and performance of the rotating electricel machineryand JB/T9577Technical requirements of series Zmiddle motor electromotor;
2.The standrd rated voltage of the electromotor are 440V550V660V 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.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.
5.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 abovecenter standards regulation.
b)The noise of the motor accords with GB10069.3Measurement of airborne noise emitted by rotating electrcal machinery and noise limits.
6.The efficiencies listed in the data sheet are for rated output, voltage and speed,and include excitation loss.
