rolling mill dc motor 

The insulation class of the motor is F
All the motors of system are with compensate winding

Technical parameters

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°C;COOling water temperature   maximal32°C;
    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.
   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.
    a)First kind(A)motor can endure the overload(1min)according to table 3
