Factory large electric DC motor
Brief introduction
Z series Large Size DC motor has a polygon structure, which contributes to high using rate of the stator's inner space. 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 outstanding.
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..
There are two types of DC motors: ordinary DC motor and metal rolling mill DC motor.
ordinary DC motor & metal rolling mill DC motor
ordinary DC motor: The buyer can decide the capacity, voltage, running speed and the method of cooling of the motor. For more technical parameters, please kindly check the following chart.

Cooling Method&Structure
1. The methods and defend class of the motor
a) The method of cooling of the motor is separately-cooled, according to the GB/T1993 "Method of cooling of rotating electrical machinery", there are IC06, IC17, IC37, IC86W. Standard entrance of cooling air is at the end of the main transmission (not the commutator side).The defend class of the motor can be divided into IP23 and IP44 according to the GB/T4942.1 "the crust defend class of rotating electrical machinery (IP code)". If the user needs other method of cooling and defend class, it can be negotiated.
b) The relation between the method of cooling and the defend class of the motor please see Table
