1TDMK/TM series synchronous motors (which includes TDMK collection brushed synchronous motors and TMW series brushless synchronous motors) are extensively employed in mining, cement and other industries. It is mostly employed to push mechanical equipment with reduce pace and larger electricity, and the primary transmission grid type ball mill, rod mill, and coal mill. This sequence of motors adopts new technological innovation, new supplies, new processes, beautiful materials choice, and innovative production. It has the traits of modest dimensions, gentle weight, early physical appearance, substantial effectiveness, low sounds, reduced vibration, protected and dependable operation, and practical and risk-free use and routine maintenance. .
This series of synchronous motors are divided into two sorts: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be used with a pneumatic clutch (the pneumatic clutch needs to be ready by the person), and the shaft not punching motor demands a greater commencing performance (please specify when ordering)

3CZPT attributes
TDMK series shaft-punching synchronous motors, whose starting up approach is employed with pneumatic clutch, can comprehend the segmented starting of synchronous motor and mill load, with tiny affect on the user’s energy grid, and making it possible for entire voltage immediate commencing.
TDMK sequence shafts are not perforated synchronous motors with very substantial beginning performance, which can meet up with the requirements of end users to begin straight with load.
TDMK series synchronous motors have high functioning stability and robust overload capability. When the grid voltage drops or the motor is overloaded, the excitation program can instantly change and implement powerful excitation to make certain the balance of the motor.
The safety device is innovative and full. Stator windings and bearings are equipped with temperature detection units, which can check, alarm and excursion.
TMW sequence brushless synchronous motors, its brushless excitation technique adopts a rotating rectifier, a rotating armature AC principal excitation equipment, and a coaxial built-in composition with the synchronous motor. It has automated de-excitation defense and automatic excitation at the greatest time of polarity. The intelligent automatic manage purpose of load out-of-step re-stepping and out-of-stage protection has a large degree of security and fast response overall performance, and the energy supply technique voltage transiently fluctuates and brings about oscillation or the driven mechanical products and procedure flow appear When the transient disturbance is powerful, the motor has the function of computerized clever security and handle, which has a significantly smaller sized affect on the procedure of the motor than the traditional brushed synchronous motor.
4. Composition variety
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep gap (consumption gap) 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 collection brushless synchronous motors is geared up with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush framework of TDMK sequence motors to provide excitation for the motor.
Stator: The stator body is welded by metal plate, and the motor stator outlet is led by substantial-voltage rubber cable. The outlet wire can be led out from the base element or from the principal junction box on the electrical side.
The stator core is laminated with low-reduction silicon steel sheets, and the core sections are divided by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature rise is assessed in accordance to B grade to support prolong the support life. Employing VPI overall dipping paint therapy, it has high electrical overall performance, mechanical toughness, bonding overall performance, humidity resistance and thermal steadiness.
The rotor magnetic pole main is produced of laminated metal plates, and the magnetic pole coils are insulated with course F.
When the consumer adopts the pneumatic clutch, the shaft can be punched in accordance to the user’s specifications. The rotor support is produced of forged metal.
TDMK collection brushed synchronous motors are geared up with metal 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 bottom plate is a steel plate welded construction, which is welded with a 20-30mm metal plate.
Undertake seat type spherical sliding bearing. The bearings are insulated to stop shaft currents. Use new lubricating oil and slender-walled bearing alloy bushes, and established electromagnetic centerline signs.
TMW collection brushless synchronous motors have tiny rotary rectifier discs, compact constructions and electrical connections. The fastened elements and the warmth sink are built-in, which is trustworthy in procedure, reduced in failure rate, and practical in installation and routine maintenance.
