1TDMK/TM series synchronous motors (such as TDMK collection brushed synchronous motors and TMW collection brushless synchronous motors) are widely utilized in mining, cement and other industries. It is largely utilised to generate mechanical gear with reduced speed and greater electricity, and the major transmission grid sort ball mill, rod mill, and coal mill. This sequence of motors adopts new technologies, new materials, new procedures, exquisite content selection, and advanced manufacturing. It has the attributes of little size, light excess weight, early appearance, high efficiency, low sounds, minimal vibration, risk-free and reliable operation, and handy and safe use and maintenance. .
This sequence of synchronous motors are divided into two kinds: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be employed with a pneumatic clutch (the pneumatic clutch requirements to be well prepared by the person), and the shaft not punching motor wants a greater beginning functionality (please specify when ordering)

3CZPT characteristics
TDMK collection shaft-punching synchronous motors, whose beginning technique is utilized with pneumatic clutch, can recognize the segmented commencing of synchronous motor and mill load, with minor affect on the user’s energy grid, and enabling total voltage direct starting.
TDMK series shafts are not perforated synchronous motors with extremely higher commencing overall performance, which can satisfy the wants of consumers to begin directly with load.
TDMK sequence synchronous motors have higher operating balance and robust overload capability. When the grid voltage drops or the motor is overloaded, the excitation method can instantly alter and apply robust excitation to make sure the steadiness of the motor.
The protection system is advanced and complete. Stator windings and bearings are outfitted with temperature detection gadgets, which can keep an eye on, alarm and vacation.
TMW series brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC primary excitation machine, and a coaxial integrated construction with the synchronous motor. It has automatic de-excitation security and computerized excitation at the very best time of polarity. The intelligent computerized management operate of load out-of-step re-stepping and out-of-step security has a high diploma of security and quick response performance, and the electrical power offer system voltage transiently fluctuates and leads to oscillation or the driven mechanical products and procedure movement look When the transient disturbance is sturdy, the motor has the function of computerized smart safety and control, which has a significantly more compact impact on the operation of the motor than the traditional brushed synchronous motor.
four. Framework kind
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep gap (consumption gap) at the middle of the tail of the shaft, and an air hole at the shaft extension end for putting in a pneumatic clutch. The shaft of TMW series brushless synchronous motors is geared up with a coaxial rotating rectifier and rotating armature AC principal exciter, which replaces the collector ring and brush structure 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 element or from the primary junction box on the electrical aspect.
The stator main is laminated with minimal-decline silicon steel sheets, and the core sections are separated by radial ventilation ducts.
The stator winding is F quality insulation, and the temperature increase is assessed according to B grade to aid extend the services daily life. Employing VPI overall dipping paint treatment, it has high electrical overall performance, mechanical energy, bonding overall performance, humidity resistance and thermal stability.
The rotor magnetic pole main is created of laminated metal 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 demands. The rotor assist is created of forged metal.
TDMK series brushed synchronous motors are equipped with metal slip rings on the shaft. An AC exciter and a rotating rectifier plate are installed on the shaft of the TMW sequence brushless synchronous motor. The base plate is a steel plate welded structure, which is welded with a twenty-30mm steel plate.
Adopt seat type spherical sliding bearing. The bearings are insulated to avert shaft currents. Use new lubricating oil and thin-walled bearing alloy bushes, and set electromagnetic centerline symptoms.
TMW series brushless synchronous motors have tiny rotary rectifier discs, compact buildings and electrical connections. The mounted elements and the heat sink are integrated, which is reputable in operation, reduced in failure fee, and practical in installation and servicing.
