1TDMK/TM series synchronous motors (including TDMK series brushed synchronous motors and TMW sequence brushless synchronous motors) are extensively utilised in mining, cement and other industries. It is mostly used to generate mechanical products with reduced pace and larger electricity, and the major transmission grid kind ball mill, rod mill, and coal mill. This series of motors adopts new technological innovation, new supplies, new procedures, exquisite content assortment, and sophisticated production. It has the characteristics of tiny dimensions, gentle weight, early physical appearance, large performance, reduced noise, reduced vibration, safe and trustworthy operation, and convenient and risk-free use and upkeep. .

This sequence of synchronous motors are divided into two kinds: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be employed with a pneumatic clutch (the pneumatic clutch requirements to be geared up by the user), and the shaft not punching motor needs a greater starting up functionality (make sure you specify when ordering)
2Basic parameters
Electricity selection: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated velocity: 150, 167, 187.5, 200r/min etc., defense degree: IP00IP20IP23IP44IP54 Functioning technique: S1, cooling strategy :IC01IC37IC81W
Set up method: IM7311IM7312IM7321 And many others

3CZPT qualities
TDMK sequence shaft-punching synchronous motors, whose beginning strategy is used with pneumatic clutch, can recognize the segmented starting of synchronous motor and mill load, with little influence on the user’s electricity grid, and enabling entire voltage direct beginning.
TDMK series shafts are not perforated synchronous motors with very substantial beginning efficiency, which can satisfy the wants of end users to commence directly with load.
TDMK collection synchronous motors have large running stability and powerful overload ability. When the grid voltage drops or the motor is overloaded, the excitation program can immediately alter and put into action robust excitation to make certain the security of the motor.
The defense device is sophisticated and comprehensive. Stator windings and bearings are outfitted with temperature detection devices, which can monitor, alarm and excursion.
TMW collection brushless synchronous motors, its brushless excitation technique adopts a rotating rectifier, a rotating armature AC primary excitation equipment, and a coaxial integrated construction with the synchronous motor. It has computerized de-excitation defense and computerized excitation at the best time of polarity. The clever automated control purpose of load out-of-phase re-stepping and out-of-step security has a substantial degree of balance and fast reaction overall performance, and the power supply program voltage transiently fluctuates and triggers oscillation or the driven mechanical products and approach stream seem When the transient disturbance is strong, the motor has the function of automated intelligent safety and manage, which has a much more compact influence on the procedure of the motor than the standard brushed synchronous motor.

four. Composition kind
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep hole (ingestion hole) at the center of the tail of the shaft, and an air gap at the shaft extension stop for setting up a pneumatic clutch. The shaft of TMW series brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC main exciter, which replaces the collector ring and brush composition of TDMK series motors to give excitation for the motor.
Stator: The stator frame is welded by metal plate, and the motor stator outlet is led by higher-voltage rubber cable. The outlet wire can be led out from the base portion or from the principal junction box on the electrical facet.

The stator core is laminated with reduced-reduction silicon metal sheets, and the core sections are separated by radial ventilation ducts.
The stator winding is F quality insulation, and the temperature increase is assessed in accordance to B quality to assist extend the services daily life. Using VPI overall dipping paint treatment, it has higher electrical overall performance, mechanical toughness, bonding performance, moisture resistance and thermal security.
The rotor magnetic pole core is manufactured of laminated steel plates, and the magnetic pole coils are insulated with class F.
When the person adopts the pneumatic clutch, the shaft can be punched according to the user’s demands. The rotor assist is produced of cast steel.
TDMK collection brushed synchronous motors are geared up with metal slip rings on the shaft. An AC exciter and a rotating rectifier plate are mounted on the shaft of the TMW collection brushless synchronous motor. The bottom plate is a steel plate welded structure, which is welded with a 20-30mm steel plate.

Undertake seat type spherical sliding bearing. The bearings are insulated to avoid shaft currents. Use new lubricating oil and thin-walled bearing alloy bushes, and established electromagnetic centerline symptoms.
TMW sequence brushless synchronous motors have modest rotary rectifier discs, compact constructions and electrical connections. The set elements and the warmth sink are built-in, which is dependable in operation, low in failure price, and handy in installation and maintenance.
