Large-Sized 3-Phase Synchronous Motor Series TM Special for Mills in Mines

 This sequence is suited to work in these kinds of an indoor setting with an altitude not much more than 1,000m and a coolant temperature not a lot more than 40ºC, with much less dust, and CZPT vapour, acid, alkali or corrosive/explosive gas. The rated voltage is 6000V for this series, and we can layout with 3000V and 10000Vaccording to the requirements from the consumers. Its allowable voltage deviation selection is +five%, rated provide frequency 50Hz and rated power aspect .nine (direct).
    The motor has a cylindrical shaft extension, whose rotation path shall be regular with that on the nameplate, ordinarily anticlockwise when witnessed from the conclude of gathering ring, and also, we can create the ones with a clockwise rotation. When a coupling is employed to link the motor and a mill, the motor’s shaft extension shall not bear extra radial or axial power.
    The series adopts a stationary controllable silicon exciter.
    It is authorized to be right started out at entire voltage, when these kinds of beginning mode is not authorized thanks to the capacity of the power grid of one user, it can be started out at diminished voltage, at this time, the decrease of its commencing current is in immediate proportion to its terminal voltage whilst the lower of starting up torque is in course to the sq. of its terminal voltage.
    Stator qualified prospects: six sales opportunities, respectively U1, V1, W1, U2, V2 & W2, all of which are led out by a high-voltage cabtyre cable from the terminal clamp at the base of the frame, and can be led out by a junction box CZPT according to buyer requirements.
Pedestal bearing:  ring-oiled or combined bearings adopted, mounted among baseboards and underlaid with insulating padding plates to stop shaft existing.

   Composition
    The ventilation pattern for the sequence can be an open up-variety natural air flow 1 or a completely shut duct air flow 1.
    Body: welded by steel plates, foremost-out terminal at the bottom.
    Stator: its iron main is made of piled fHangCZPT strips stamped with .5mm lower-loss silicon metal plate, and is divided by radial duct spacer stator windings undertake formed double-layer brief-pitched coils with an insulation class of B or F (temperature rise assessed in accordance to course B), that are valuable to prolong services lifestyle and because winding terminals have been fixed and strapped reliably and processed with solvent-free VPI (vacuum strain impregnation) and have long gone through several occasions of assessments for turn-to-switch impulse stand up to voltage and face up to voltage to ground, the motor has exceptional and reliable insulation overall performance, substantial mechanical toughness and robust humidity proofing.
    Rotor: its magnetic poles manufactured of stamped steel plates which are mounted at rotor field yoke together with pole coils with an insulation course of B or F. When a customer needs to adopt a pneumatic clutch, we can style a revolving shaft or a shaft with punched holes in accordance to customer specifications.
 
   Purpose
    The series is a kind of large-sized 3-phase AC synchronous motor largely employed to push mills in mines, such as grate ball mill, rod mill and coal mill.
