1TDMK/TM collection synchronous motors (like TDMK collection brushed synchronous motors and TMW sequence brushless synchronous motors) are commonly used in mining, cement and other industries. It is mostly used to generate mechanical gear with reduce speed and increased power, and the principal transmission grid kind ball mill, rod mill, and coal mill. This sequence of motors adopts new technological innovation, new components, new processes, exquisite materials choice, and innovative producing. It has the qualities of tiny dimension, light-weight weight, early appearance, high efficiency, minimal noise, minimal vibration, risk-free and reputable procedure, and practical 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 must be utilized with a pneumatic clutch (the pneumatic clutch demands to be well prepared by the person), and the shaft not punching motor wants a larger commencing functionality (make sure you specify when purchasing)

3CZPT attributes
TDMK collection shaft-punching synchronous motors, whose commencing technique is employed with pneumatic clutch, can recognize the segmented starting up of synchronous motor and mill load, with tiny influence on the user’s electricity grid, and making it possible for complete voltage immediate starting up.
TDMK sequence shafts are not perforated synchronous motors with quite higher starting up overall performance, which can fulfill the wants of consumers to commence directly with load.
TDMK series synchronous motors have large running steadiness and robust overload potential. When the grid voltage drops or the motor is overloaded, the excitation technique can immediately change and employ powerful excitation to ensure the stability of the motor.
The defense device is sophisticated and comprehensive. Stator windings and bearings are equipped with temperature detection units, which can keep track of, alarm and trip.
TMW collection brushless synchronous motors, its brushless excitation method adopts a rotating rectifier, a rotating armature AC principal excitation device, and a coaxial built-in structure with the synchronous motor. It has automatic de-excitation defense and computerized excitation at the ideal time of polarity. The clever automated management operate of load out-of-stage re-stepping and out-of-phase protection has a substantial degree of stability and quickly response overall performance, and the electrical power supply system voltage transiently fluctuates and brings about oscillation or the driven mechanical tools and method circulation appear When the transient disturbance is strong, the motor has the operate of automatic intelligent protection and control, which has a significantly more compact influence on the procedure of the motor than the standard brushed synchronous motor.
4. Composition type
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep gap (ingestion gap) at the heart of the tail of the shaft, and an air gap at the shaft extension end for installing a pneumatic clutch. The shaft of TMW collection brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush framework of TDMK collection motors to provide excitation for the motor.
Stator: The stator frame 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 part or from the primary junction box on the electrical facet.
The stator core is laminated with reduced-decline silicon steel sheets, and the main sections are divided by radial air flow ducts.
The stator winding is F grade insulation, and the temperature increase is assessed in accordance to B quality to help increase the service daily life. Utilizing VPI general dipping paint therapy, it has substantial electrical performance, mechanical power, bonding overall 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 consumer adopts the pneumatic clutch, the shaft can be punched according to the user’s specifications. The rotor assistance is made of solid steel.
TDMK series brushed synchronous motors are equipped with steel 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 base plate is a metal plate welded framework, which is welded with a 20-30mm steel plate.
Adopt seat kind spherical sliding bearing. The bearings are insulated to avoid shaft currents. Use new lubricating oil and skinny-walled bearing alloy bushes, and established electromagnetic centerline signs.
TMW sequence brushless synchronous motors have tiny rotary rectifier discs, compact structures and electrical connections. The mounted areas and the heat sink are built-in, which is trustworthy in procedure, reduced in failure rate, and practical in set up and servicing.
