1TDMK/TM collection synchronous motors (like TDMK series brushed synchronous motors and TMW collection brushless synchronous motors) are commonly employed in mining, cement and other industries. It is mainly utilized to drive mechanical gear with reduce speed and larger electrical power, and the main transmission grid type ball mill, rod mill, and coal mill. This series of motors adopts new engineering, new components, new processes, exquisite substance assortment, and sophisticated producing. It has the characteristics of small size, light-weight excess weight, early physical appearance, large efficiency, reduced noise, lower vibration, protected and reliable procedure, and convenient and secure use and servicing. .
This sequence of synchronous motors are divided into two sorts: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be employed with a pneumatic clutch (the pneumatic clutch needs to be prepared by the user), and the shaft not punching motor wants a higher commencing performance (make sure you specify when ordering)
Power assortment: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated velocity: one hundred fifty, 167, 187.five, 200r/min etc., protection stage: IP00IP20IP23IP44IP54 Operating program: S1, cooling approach :IC01IC37IC81W
Set up approach: IM7311IM7312IM7321 Etc
TDMK series shaft-punching synchronous motors, whose starting strategy is used with pneumatic clutch, can realize the segmented commencing of synchronous motor and mill load, with tiny impact on the user’s energy grid, and enabling entire voltage direct starting up.
TDMK sequence shafts are not perforated synchronous motors with very high commencing overall performance, which can satisfy the requirements of users to begin right with load.
TDMK sequence synchronous motors have high running security and powerful overload capability. When the grid voltage drops or the motor is overloaded, the excitation system can automatically change and put into action strong excitation to make certain the stability of the motor.
The protection gadget is sophisticated and total. Stator windings and bearings are outfitted with temperature detection units, which can keep track of, alarm and excursion.
TMW sequence brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC primary excitation machine, and a coaxial built-in composition with the synchronous motor. It has automated de-excitation safety and automatic excitation at the ideal time of polarity. The smart automatic management purpose of load out-of-phase re-stepping and out-of-step defense has a large degree of balance and fast response performance, and the electricity provide program voltage transiently fluctuates and brings about oscillation or the driven mechanical products and process circulation show up When the transient disturbance is sturdy, the motor has the operate of automatic clever security and handle, which has a significantly scaled-down affect on the procedure of the motor than the standard brushed synchronous motor.
four. Composition sort
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep gap (consumption hole) at the center of the tail of the shaft, and an air hole at the shaft extension conclude for putting in a pneumatic clutch. The shaft of TMW collection brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush construction of TDMK sequence motors to supply excitation for the motor.
Stator: The stator frame is welded by steel plate, and the motor stator outlet is led by high-voltage rubber cable. The outlet wire can be led out from the foundation element or from the primary junction box on the electrical facet.
The stator main is laminated with lower-decline silicon metal sheets, and the main sections are divided by radial air flow ducts.
The stator winding is F quality insulation, and the temperature rise is assessed in accordance to B grade to aid extend the support life. Utilizing VPI total dipping paint treatment, it has large electrical performance, mechanical toughness, bonding overall performance, humidity resistance and thermal balance.
The rotor magnetic pole main is created 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 needs. The rotor help is manufactured of solid steel.
TDMK sequence brushed synchronous motors are outfitted with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are mounted on the shaft of the TMW sequence brushless synchronous motor. The base plate is a steel plate welded construction, which is welded with a twenty-30mm steel plate.
Adopt seat variety spherical sliding bearing. The bearings are insulated to avoid shaft currents. Use new lubricating oil and slim-walled bearing alloy bushes, and set electromagnetic centerline indicators.
TMW collection brushless synchronous motors have modest rotary rectifier discs, compact buildings and electrical connections. The fixed elements and the warmth sink are integrated, which is reliable in procedure, low in failure charge, and hassle-free in set up and maintenance.
