Three-Phase Synchronous Motors

TDMKType: three-period synchronous motors be used in the mining market
TDMKType: 3-phase synchronous motors be utilized in the mining market
1TDMK collection synchronous motors (which includes TDMK series brushed synchronous motors and TMW series brushless synchronous motors) are widely utilised in mining, cement and other industries. It is mostly employed to travel mechanical products with reduced speed and greater electrical power, and the major transmission grid kind ball mill, rod mill, and coal mill. This collection of motors adopts new engineering, new components, new procedures, beautiful material choice, and sophisticated manufacturing. It has the characteristics of little dimension, gentle excess weight, early appearance, higher performance, minimal noise, reduced vibration, risk-free and trustworthy procedure, practical and secure use and upkeep, and many others. .
This sequence of synchronous motors are divided into two kinds: shaft drilling motors and shaft non-piercing motors. The shaft punching motor need to be used with a pneumatic clutch (the pneumatic clutch demands to be geared up by the consumer), and the shaft not punching motor wants a increased beginning overall performance (make sure you specify when buying)
2Basic parameters
Energy assortment: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated velocity: one hundred fifty, 167, 187.5, 200r/min and many others., defense stage: IP00IP20IP23IP44IP54 Doing work technique: S1, cooling technique :IC01IC37IC81W
Installation approach: IM7311IM7312IM7321 Etc
3CZPT qualities
TDMK sequence shaft-punching synchronous motors, whose beginning approach is employed with pneumatic clutch, can comprehend the segmented starting up of synchronous motor and mill load, with tiny impact on the user’s energy grid, and allowing direct beginning at entire voltage.
TDMK series shafts are not perforated synchronous motors with quite large commencing overall performance, which can fulfill the requirements of customers to commence straight with load.
TDMK sequence synchronous motors have high functioning steadiness and robust overload capability. When the grid voltage drops or the motor is overloaded, the excitation system can instantly change and put into action strong excitation to guarantee the steadiness of the motor.
The protection system is advanced and comprehensive. Stator windings and bearings are equipped with temperature detection devices, which can keep an eye on, alarm and vacation.
TMW series brushless synchronous motors, its brushless excitation technique adopts a rotating rectifier, a rotating armature AC main excitation equipment, and a coaxial built-in structure with the synchronous motor. It has computerized de-excitation security and automatic excitation at the very best time of polarity. The intelligent computerized management purpose of load out-of-action re-stepping and out-of-action defense has a high diploma of balance and quick reaction overall performance, and it appears when the electricity source system voltage fluctuates instantaneously and brings about oscillation or the driven mechanical equipment and process circulation show up When the transient disturbance is robust, the motor has the operate of automated clever defense and control, which has a considerably scaled-down affect on the operation of the motor than the conventional brushed synchronous motor.
4. Framework kind
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep hole (intake hole) at the heart of the tail of the shaft, and an air gap at the shaft extension stop for putting in a pneumatic clutch. The shaft of TMW sequence brushless synchronous motor is equipped with a coaxial rotating rectifier and a rotating armature AC main exciter, which replaces the collector ring and brush construction of TDMK collection motors to give excitation for the motor.
Stator: The stator frame is welded by metal plate, and the motor stator outlet is led by large-voltage rubber cable. The outlet wire can be led out from the base portion or from the main junction box on the electrical side.
The stator core is laminated with reduced-decline silicon steel sheets, and the core sections are divided by radial air flow ducts.
The stator winding is F quality insulation, and the temperature rise is assessed according to B quality to help extend the provider lifestyle. Making use of VPI total dipping paint remedy, it has higher electrical efficiency, mechanical strength, bonding overall performance, humidity resistance and thermal steadiness.
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 in accordance to the user’s demands. The rotor support is manufactured of forged metal.
TDMK sequence brushed synchronous motors are geared up with metal slip rings on the shaft. An AC exciter and a rotating rectifier plate are put in on the shaft of the TMW collection brushless synchronous motor. The base plate is a metal plate welded framework, which is welded with a 20-30mm metal plate.
Adopt 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 indications.
TMW series brushless synchronous motors have modest rotary rectifier discs, compact constructions and electrical connections. The fixed parts and the heat sink are built-in, which is dependable in procedure, reduced in failure charge, and convenient in set up and servicing.
