1TDMK/TM series synchronous motors (which includes TDMK collection brushed synchronous motors and TMW collection brushless synchronous motors) are widely utilized in mining, cement and other industries. It is mainly utilized to travel mechanical products with lower velocity and higher electricity, and the principal transmission grid variety ball mill, rod mill, and coal mill. This collection of motors adopts new technological innovation, new resources, new procedures, exquisite materials assortment, and innovative production. It has the qualities of modest dimensions, light-weight weight, early appearance, large performance, reduced noise, low vibration, risk-free and dependable procedure, and handy and protected use and upkeep. .
This series of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor need to be utilized with a pneumatic clutch (the pneumatic clutch demands to be geared up by the person), and the shaft not punching motor demands a higher beginning functionality (remember to specify when buying)
Electrical power variety: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated pace: a hundred and fifty, 167, 187.5, 200r/min and so forth., protection degree: IP00IP20IP23IP44IP54 Operating program: S1, cooling strategy :IC01IC37IC81W
Installation method: IM7311IM7312IM7321 Etc
TDMK series shaft-punching synchronous motors, whose starting up strategy is utilised with pneumatic clutch, can realize the segmented starting of synchronous motor and mill load, with little effect on the user’s electrical power grid, and permitting full voltage immediate starting.
TDMK sequence shafts are not perforated synchronous motors with really large starting functionality, which can satisfy the wants of end users to start off immediately with load.
TDMK sequence synchronous motors have higher running security and strong overload capability. When the grid voltage drops or the motor is overloaded, the excitation technique can routinely alter and implement strong excitation to make certain the security of the motor.
The protection unit is sophisticated and complete. Stator windings and bearings are equipped with temperature detection gadgets, which can check, alarm and trip.
TMW sequence brushless synchronous motors, its brushless excitation technique adopts a rotating rectifier, a rotating armature AC major excitation device, and a coaxial integrated structure with the synchronous motor. It has computerized de-excitation safety and computerized excitation at the greatest time of polarity. The clever computerized handle function of load out-of-stage re-stepping and out-of-step security has a higher degree of stability and fast response functionality, and the energy supply program voltage transiently fluctuates and leads to oscillation or the driven mechanical equipment and method circulation show up When the transient disturbance is powerful, the motor has the operate of automated smart security and management, which has a much smaller impact on the operation of the motor than the traditional brushed synchronous motor.
4. Construction type
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep gap (consumption gap) at the heart of the tail of the shaft, and an air hole at the shaft extension end for putting in a pneumatic clutch. The shaft of TMW sequence brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush structure of TDMK series motors to provide excitation for the motor.
Stator: The stator body is welded by steel plate, and the motor stator outlet is led by higher-voltage rubber cable. The outlet wire can be led out from the base element or from the primary junction box on the electrical aspect.
The stator core is laminated with reduced-loss silicon metal sheets, and the main sections are separated by radial air flow ducts.
The stator winding is F quality insulation, and the temperature increase is assessed according to B grade to aid extend the provider existence. Making use of VPI all round dipping paint remedy, it has large electrical performance, mechanical power, bonding functionality, dampness resistance and thermal stability.
The rotor magnetic pole core is made of laminated metal plates, and the magnetic pole coils are insulated with class F.
When the consumer adopts the pneumatic clutch, the shaft can be punched according to the user’s demands. The rotor assist is produced of solid metal.
TDMK series brushed synchronous motors are equipped with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are put in on the shaft of the TMW series brushless synchronous motor. The base plate is a steel plate welded framework, which is welded with a twenty-30mm metal plate.
Adopt seat variety spherical sliding bearing. The bearings are insulated to avoid shaft currents. Use new lubricating oil and slender-walled bearing alloy bushes, and established electromagnetic centerline indicators.
TMW sequence brushless synchronous motors have small rotary rectifier discs, compact buildings and electrical connections. The fixed areas and the warmth sink are integrated, which is dependable in procedure, reduced in failure charge, and convenient in installation and upkeep.
