Motor frame Motor frame: the use of domestic high-quality 45
# steel plate welded processing, with surface processing size
tolerance should be less than 0.01mm, to ensure that the mechanical
properties of the motor. Motor spindle Spindle material
forged 45A steel. After quenched and tempered after rough car, fine
car, washing, grinding and other processes from processing, to
ensure the overall mechanical properties of the spindle and
precision tolerance size. Stator rotor core (1) fixed rotor core is
the use of low loss, high permeability, high stacking coefficient,
the surface of the insulating film adhesion and good weldability,
no time, the thickness of 0.5mm electrician high-quality grain
non-oriented cold rolling Silicon steel sheet laminated. Cold
rolled silicon steel sheet performance indicators should not be
less than GB2521-88 requirements, the material used by the
performance of not less than 50W310. Each piece of silicon steel
sheet should be no burr, both sides coated with F-class insulation
material paint to reduce the eddy current loss. (2) fixed rotor
core ventilation groove layout so that the air flow smooth and
smooth, so that the stator core is fully cooled, the wind
resistance loss is small. Stator winding coil Stator winding
coil using domestic high-quality manufacturers to provide the
F-class insulation grade enameled wire or double glass fiber flat
copper wire wound around. In the manufacturing process after
several inter-turn pulse voltage test and ground pressure test. The
stator rotor winding is embedded in the core The stator
rotor winding: 100% pure copper flat copper bending, F-class
insulation mica wrapped. Stator rotor winding wiring In the
manufacturing process with silver copper argon arc welding, and
with F-class insulation mica will be welded at the package so the
motor insulation performance is excellent and reliable, good
mechanical strength, moisture resistance. Stator winding
rotor winding vacuum impregnation Using foreign advanced vacuum
pressure impregnation solvent-free paint equipment and process
(VPI) treatment. Has a good anti-corona and anti-corrosion
resistance, in the groove, the end of the site to take anti-halo
measures. Therefore, the motor insulation performance is excellent
and reliable, good mechanical strength, moisture resistance. Rotor
fine processing and dynamic balance check Rotor fine processing to
ensure the stability of the stator and rotor between the uniform
Dynamic balancing checks ensure good mechanical performance of the
motor. Machine assembly and experiment experimental

connection: Y (three outlet terminals in the junction box, the
junction box from the extension of the spindle is located on the
right side of the base)Altitude: no more than 1000mThis type of
motor is suitable for use in environments where the ambient air
temperature does not exceed 40 ° C and there is no serious
dust, the minimum ambient air temperature is -15 ° C, and
there is no corrosive and explosive gas in the air (which can also
be made into a damp heat or high-altitude motor).The
high-quality slip ring motor is a sliding wrap-around
three-phase asynchronous motor that can increase the starting
torque at a small starting current. The motor is suitable for
applications where the capacity of the feeder line is insufficient
to start the squirrel-cage rotor, the starting time is long, the
starting is frequent, and the small-range speed regulation is
required. This series of motors has the advantages of high
efficiency, energy saving, low noise, low vibration, light weight,
reliable performance, convenient installation and maintenance.Main

high-quality motor products and services to users, and has won high
praise from many domestic and foreign customers. The company will
receive many foreign merchants to visit our factory every year, and
establish a good cooperative relationship through on-site
inspection of our factory. Our company always welcomes custome
