1TDMK/TM collection synchronous motors (like TDMK sequence brushed synchronous motors and TMW sequence brushless synchronous motors) are broadly used in mining, cement and other industries. It is primarily utilized to generate mechanical products with lower velocity and higher electrical power, and the main transmission grid kind ball mill, rod mill, and coal mill. This series of motors adopts new technology, new materials, new procedures, exquisite content variety, and refined production. It has the traits of modest size, light-weight bodyweight, early appearance, high performance, low sound, reduced vibration, secure and dependable operation, and hassle-free and risk-free use and upkeep. .
This series of synchronous motors are divided into two varieties: shaft drilling motors and shaft non-piercing motors. The shaft punching motor should be utilized with a pneumatic clutch (the pneumatic clutch requirements to be ready by the person), and the shaft not punching motor wants a increased commencing overall performance (remember to specify when purchasing)
Power range: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated pace: a hundred and fifty, 167, 187.five, 200r/min and many others., protection degree: IP00IP20IP23IP44IP54 Functioning program: S1, cooling strategy :IC01IC37IC81W
Set up method: IM7311IM7312IM7321 And so forth
TDMK series shaft-punching synchronous motors, whose starting up technique is utilized with pneumatic clutch, can comprehend the segmented beginning of synchronous motor and mill load, with small effect on the user’s electrical power grid, and permitting complete voltage direct starting.
TDMK series shafts are not perforated synchronous motors with quite large starting up overall performance, which can satisfy the needs of end users to begin straight with load.
TDMK collection synchronous motors have high running security and strong overload capacity. When the grid voltage drops or the motor is overloaded, the excitation technique can routinely change and put into action sturdy excitation to guarantee the security of the motor.
The security device is innovative and total. Stator windings and bearings are outfitted with temperature detection devices, which can check, alarm and excursion.
TMW collection brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC major excitation device, and a coaxial built-in construction with the synchronous motor. It has automatic de-excitation security and automated excitation at the very best time of polarity. The smart automatic management purpose of load out-of-step re-stepping and out-of-action security has a substantial diploma of balance and quick reaction overall performance, and the electrical power provide program voltage transiently fluctuates and triggers oscillation or the pushed mechanical tools and approach flow look When the transient disturbance is robust, the motor has the perform of automatic smart protection and handle, which has a much more compact influence on the procedure of the motor than the conventional brushed synchronous motor.
4. Construction variety
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep gap (intake gap) at the center of the tail of the shaft, and an air hole at the shaft extension stop for installing a pneumatic clutch. The shaft of TMW sequence brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC principal exciter, which replaces the collector ring and brush composition of TDMK sequence motors to supply excitation for the motor.
Stator: The stator body 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 principal junction box on the electrical aspect.
The stator core is laminated with reduced-loss silicon metal sheets, and the main sections are separated by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature rise is assessed according to B grade to support increase the provider daily life. Employing VPI overall dipping paint remedy, it has substantial electrical functionality, mechanical energy, bonding performance, dampness resistance and thermal security.
The rotor magnetic pole main is created of laminated metal plates, and the magnetic pole coils are insulated with course F.
When the user adopts the pneumatic clutch, the shaft can be punched in accordance to the user’s demands. The rotor support is manufactured of cast metal.
TDMK sequence brushed synchronous motors are geared up with metal slip rings on the shaft. An AC exciter and a rotating rectifier plate are set up on the shaft of the TMW collection brushless synchronous motor. The bottom plate is a metal plate welded composition, which is welded with a 20-30mm steel plate.
Adopt seat type 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 indications.
TMW sequence brushless synchronous motors have small rotary rectifier discs, compact buildings and electrical connections. The mounted components and the heat sink are built-in, which is trustworthy in operation, lower in failure price, and handy in set up and maintenance.
