A summary of the series of high-voltage motors,
for altitude does not exceed 1000m, the environment temperature is below 40 ℃, less dust, no steam, acid, alkali and other corrosive gases indoor environment.
the series high voltage motor for rated voltage of 6000V or 10000V, allowable error voltage of ± 5%, rated power supply frequency is 50Hz, rated power factor is 0.9 (lead).
motor has a cylindrical shaft extension end, the rotation direction of the motor should be stipulated and pointing to the board of the direction, the direction of rotation by the collector ring side generally anticlockwise;
the series of high-voltage motors are mainly used to drive a variety of mine mill machinery,Coupling connection shaft extension may not have to remove the coupling weight outside of the external axial and radial force.
the synchronous motor excitation system with controllable silicon excitation device. The motor to allow direct starting pressure, when the power grid capacity does not allow full voltage starting, can also be reduced voltage starting, at this time, the starting current of the motor and the end is directly proportional to the voltage drop, and the starting torque and the terminal voltage is proportional to the square of the fall.
the pedestal bearing, oil ring type and combined type two kinds, insulating lining plate is provided with a seat type bearing and the mounting plate, to prevent the shaft current.
two, structure of
TDMK (TM) large AC three-phase synchronous motor for mine mill,The base for the steel plate welded structure, with the chassis; the level of protection IP00, cooling mode IC01, mounting type IM7311 or without the shaft and the bearing pedestal IM5710, quota type S1, stator winding wiring method Y, insulation class F (assessment according to B grade). 0.5 mm thick low loss silicon steel sheet sector laminations of pressure by
stator, directional ventilation slot iron core, stator winding adopts forming double overlapping short rectangular coil, the insulation class is F;
rotor pole with steel plate punching, and pole coil are mounted on the rotor magnet yoke, pole coil F pole insulation, when the user adopts pneumatic clutch,According to the design of the shaft or shaft drilling user requirements.
three
, use this series motors is mainly used for transmission of mine mill, mainly as a prime mover of lattice type ball mill, rod mill, coal mill.
