TXZ large scale AC 3ph brushless Synchronous Motor for mining mill,coal mill,cement industry,big starting torque

TXZ series synchronous motor, the main speed is 250r/min, this series of motors is installed at an angle of 30°, mainly used for drainage pumping stations, the protection grades are mainly IP20, IP21, IP23

structure type
Cooling method: The motor is cooled by IC81W or IC91W.
Protection class: If there are exposed live parts inside the main shell of the synchronous motor, the protection class of the shell is IP54. If the shell has taken dustproof measures to reduce the amount of dust, all the exposed live parts inside the shell except the windings are all insulated. Then the protection grade of the main body shell of the motor can be IP44.

Installation method: According to the matching requirements of the compressor, the basic structure and installation method of the motor can be made into IM7311, IM7315, IM7312, IM7317, IM7115, etc., among which:
a) IM7311—two seat type bearings, one cylindrical shaft extension, horizontal installation, raised feet, and a whole bottom plate;
b) IM7315—two seat type bearings, one flange shaft extension, horizontal installation, raised feet, and a whole bottom plate;
c) IM7312—two seat type bearings, two cylindrical shaft extensions, horizontal installation, raised feet, and a whole bottom plate;
d) IM7317—two seat type bearings, one end is a flange shaft extension, the other end is a cylindrical shaft extension, installed horizontally, the feet are raised, and there is a whole bottom plate;
e) IM7115—One seat bearing for non-shaft extension end (the extension end shares one bearing with the load), one flanged shaft extension, horizontal installation, raised feet, and a whole bottom plate.

Motors with different cooling methods, protection levels and installation methods can also be made according to user requirements.

The overall structure of the motor is a square box structure, with beautiful appearance and compact structure. Including stator, rotor, AC exciter, rotating commutating disc, static excitation device, junction box, bearing, cooler (including water leakage protector), base, etc. The main motor is an independent cavity, the AC exciter and the rotating commutating disc are located outside the non-drive end seat bearing, and the main motor adopts an air duct system, which is exchanged with the cooling air at the rear end of the main motor through the ventilation holes left in the base of the motor. heat. If the motor is driven by double shaft extension, the exciter and rotating commutator can be built in. The AC exciter, the rotating rectifier disc and the rotor of the main engine are coaxially connected, and the excitation lead penetrates the inside of the rotor through the central lead hole of the shaft.
