1TDMK/TM sequence synchronous motors (such as TDMK series brushed synchronous motors and TMW collection brushless synchronous motors) are commonly utilized in mining, cement and other industries. It is mostly utilized to travel mechanical equipment with reduce velocity and higher energy, and the main transmission grid variety ball mill, rod mill, and coal mill. This sequence of motors adopts new technology, new components, new processes, exquisite material selection, and advanced producing. It has the attributes of small dimension, gentle weight, early visual appeal, substantial effectiveness, reduced noise, lower vibration, safe and reliable procedure, and convenient and protected use and routine maintenance. .
This series of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be utilized with a pneumatic clutch (the pneumatic clutch requirements to be geared up by the user), and the shaft not punching motor requirements a greater commencing functionality (make sure you specify when ordering)

3CZPT characteristics
TDMK collection shaft-punching synchronous motors, whose beginning strategy is used with pneumatic clutch, can understand the segmented beginning of synchronous motor and mill load, with tiny effect on the user’s electricity grid, and permitting entire voltage direct starting up.
TDMK series shafts are not perforated synchronous motors with quite higher beginning overall performance, which can fulfill the wants of consumers to begin right with load.
TDMK collection synchronous motors have higher running balance and robust overload capability. When the grid voltage drops or the motor is overloaded, the excitation program can routinely adjust and implement strong excitation to make sure the balance of the motor.
The security device is sophisticated and comprehensive. Stator windings and bearings are equipped with temperature detection devices, which can keep track of, alarm and vacation.
TMW series brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC main excitation machine, and a coaxial built-in composition with the synchronous motor. It has computerized de-excitation safety and computerized excitation at the best time of polarity. The intelligent automated manage function of load out-of-phase re-stepping and out-of-phase protection has a large degree of steadiness and quickly response performance, and the power supply program voltage transiently fluctuates and brings about oscillation or the driven mechanical equipment and method circulation show up When the transient disturbance is sturdy, the motor has the purpose of automated clever protection and control, which has a significantly more compact impact on the procedure of the motor than the classic brushed synchronous motor.
four. Framework type
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep hole (consumption hole) at the centre of the tail of the shaft, and an air gap at the shaft extension end for installing a pneumatic clutch. The shaft of TMW series brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC principal exciter, which replaces the collector ring and brush framework of TDMK sequence motors to supply 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 foundation element or from the primary junction box on the electrical facet.
The stator core is laminated with lower-decline silicon steel sheets, and the core sections are separated by radial air flow ducts.
The stator winding is F quality insulation, and the temperature rise is assessed according to B quality to aid prolong the services life. Making use of VPI all round dipping paint treatment, it has high electrical overall performance, mechanical toughness, bonding overall performance, dampness resistance and thermal stability.
The rotor magnetic pole main is manufactured of laminated metal 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 assist is produced of cast steel.
TDMK series brushed synchronous motors are outfitted with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are put in on the shaft of the TMW sequence brushless synchronous motor. The bottom plate is a metal plate welded composition, which is welded with a 20-30mm metal 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 signs.
TMW sequence brushless synchronous motors have small rotary rectifier discs, compact structures and electrical connections. The fastened components and the heat sink are built-in, which is dependable in operation, low in failure price, and practical in set up and servicing.
