This series Motors uses the advanced design, stator polygons overlapping structures, full use of the space, with small size, light weight, performance and other advantages. Stator yoke, Poles, armature cores are made of high quality cold rolled silicon steel plate pressure-superposed to become, with good magnetic performance. Stator and rotor as a whole the Rong JI paint-free vacuum pressure impregnation (VPl), the winding has the ability of waves of resistance and mechanical strength, and good insulation and thermal conductivity properties.This series Motors shafts adopted ball bearing, without stopping the fuel structure, insulation class h class. 
DC units of this series are not only supply, better suited for static rectifying power supply. And the moment of inertia is small, only better dynamic performance, and able to withstand high load rate of change, particularly for applications requiring smooth speed control, high efficiency, automatic speed control, responsive control system. 
structure, protection degree and type cooling 
1. The series for the mounting type is compliant with GB/T997 and IEC34-7 of the motor structure and installation code. 
2. Enclosure protection class in accordance with GB/T4942.1 and IEC34-5 of the motor casing protection rating standards, 
casing protection degree IP23 and 1P44 two. 
3. Enclosure cooling methods according to the standards of GB/T1993 and IEC34-6 of the motor cooling method has the following four users for other protection class and cooling methods can be consulted separately. This series standard type motor cooling air intake at the drive end of the motor (non-commutator end). 
3.1.IC06: external ventilation with blower: (protection class IP23). 
3.2.IC17: cooling air inlet pipe; export-blinds, ventilation;(Protection IP23). 
3.3.IC37: cooling air import and export for the pipeline, (protection class 1P44). 
3.4.ICW37A86: totally enclosed with air/water cooler. (Protection class IP44). 

The use of conditions.

Means the motor rated at an altitude not exceeding 1000 m, ambient air temperature does not exceed 40 ° c conditions. 
2. This series circuit and the motor armature excitation circuit adapted to SCR power supply, also powered by a DC generator. 
3. This series motors, adaptation of work environment does not contain acid, alkali or other insulation has a corrosive effect on gas. 
4. Bad motor can be installed in environmental conditions. But you must choose the correct method of cooling and protection level, to protect the motor in normal operation. 
5. Motor as used in ships and wet tropical areas and salt spray, humidity, such as in the working environment, shall be separate agreements. 
6. When the motor is stationary while rectifying power, number of pulse rectifier should be not less than 6, rated base speed, under rated voltage and the rated load current, peak ripple factor of the power supply does not exceed 10%.
