1TDMK/TM series synchronous motors (which includes TDMK series brushed synchronous motors and TMW sequence brushless synchronous motors) are extensively utilized in mining, cement and other industries. It is mostly used to travel mechanical equipment with lower velocity and greater electrical power, and the primary transmission grid variety ball mill, rod mill, and coal mill. This series of motors adopts new technology, new resources, new processes, beautiful content variety, and advanced production. It has the attributes of small size, light excess weight, early appearance, high performance, minimal sound, lower vibration, safe and trustworthy procedure, and practical and protected use and maintenance. .

This sequence of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be employed with a pneumatic clutch (the pneumatic clutch wants to be ready by the consumer), and the shaft not punching motor demands a higher beginning performance (remember to specify when purchasing)

3CZPT traits
TDMK series shaft-punching synchronous motors, whose beginning approach is used with pneumatic clutch, can recognize the segmented commencing of synchronous motor and mill load, with tiny affect on the user’s power grid, and making it possible for entire voltage immediate starting up.
TDMK sequence shafts are not perforated synchronous motors with very large starting efficiency, which can meet up with the requirements of users to start immediately with load.
TDMK sequence synchronous motors have substantial operating steadiness and robust overload potential. When the grid voltage drops or the motor is overloaded, the excitation program can routinely modify and put into action robust excitation to ensure the security of the motor.
The safety unit is advanced and full. Stator windings and bearings are outfitted with temperature detection devices, which can monitor, alarm and excursion.
TMW collection brushless synchronous motors, its brushless excitation method adopts a rotating rectifier, a rotating armature AC main excitation machine, and a coaxial integrated structure with the synchronous motor. It has automatic de-excitation safety and automated excitation at the ideal time of polarity. The smart automated management purpose of load out-of-stage re-stepping and out-of-step safety has a large degree of balance and quickly response performance, and the electricity supply technique voltage transiently fluctuates and causes oscillation or the pushed mechanical tools and procedure movement look When the transient disturbance is powerful, the motor has the perform of computerized smart security and control, which has a considerably smaller sized effect on the operation of the motor than the standard brushed synchronous motor.

four. Construction sort
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep hole (intake hole) at the centre of the tail of the shaft, and an air hole at the shaft extension stop for setting up a pneumatic clutch. The shaft of TMW sequence brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC main exciter, which replaces the collector ring and brush structure of TDMK series 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 base element or from the major junction box on the electrical aspect.

The stator main is laminated with minimal-reduction silicon metal 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 aid prolong the service daily life. Making use of VPI overall dipping paint remedy, it has higher electrical functionality, mechanical toughness, bonding overall performance, moisture resistance and thermal security.
The rotor magnetic pole core is produced 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 help is made of forged metal.
TDMK sequence brushed synchronous motors are geared up with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are mounted on the shaft of the TMW series brushless synchronous motor. The base plate is a steel plate welded composition, which is welded with a 20-30mm metal plate.

Undertake seat kind spherical sliding bearing. The bearings are insulated to prevent shaft currents. Use new lubricating oil and slim-walled bearing alloy bushes, and set electromagnetic centerline indicators.
TMW series brushless synchronous motors have little rotary rectifier discs, compact structures and electrical connections. The fixed components and the heat sink are built-in, which is dependable in procedure, lower in failure rate, and handy in set up and routine maintenance.
