1TDMK/TM series synchronous motors (including TDMK sequence brushed synchronous motors and TMW sequence brushless synchronous motors) are widely used in mining, cement and other industries. It is largely used to generate mechanical tools with reduce speed and higher energy, and the primary transmission grid variety ball mill, rod mill, and coal mill. This collection of motors adopts new technology, new materials, new processes, exquisite content selection, and advanced producing. It has the traits of small size, mild fat, early visual appeal, large performance, reduced sounds, reduced vibration, secure and trustworthy operation, and hassle-free and secure use and routine maintenance. .
This sequence of synchronous motors are divided into two sorts: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be utilised with a pneumatic clutch (the pneumatic clutch requirements to be geared up by the consumer), and the shaft not punching motor requirements a greater beginning efficiency (please specify when purchasing)
Electrical power range: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated pace: a hundred and fifty, 167, 187.five, 200r/min and so forth., safety level: IP00IP20IP23IP44IP54 Operating program: S1, cooling strategy :IC01IC37IC81W
Installation approach: IM7311IM7312IM7321 And so on
TDMK sequence shaft-punching synchronous motors, whose commencing approach is utilized with pneumatic clutch, can realize the segmented commencing of synchronous motor and mill load, with little influence on the user’s electrical power grid, and allowing total voltage direct beginning.
TDMK collection shafts are not perforated synchronous motors with really large beginning functionality, which can meet up with the requirements of consumers to start straight with load.
TDMK sequence synchronous motors have large running balance and powerful overload ability. When the grid voltage drops or the motor is overloaded, the excitation technique can instantly adjust and employ strong excitation to guarantee the stability of the motor.
The safety system is superior and complete. Stator windings and bearings are outfitted with temperature detection units, which can keep track of, alarm and trip.
TMW collection brushless synchronous motors, its brushless excitation method adopts a rotating rectifier, a rotating armature AC major excitation equipment, and a coaxial integrated structure with the synchronous motor. It has computerized de-excitation security and computerized excitation at the ideal time of polarity. The smart automated manage purpose of load out-of-phase re-stepping and out-of-step defense has a large degree of security and rapidly reaction efficiency, and the power offer method voltage transiently fluctuates and leads to oscillation or the driven mechanical gear and procedure stream show up When the transient disturbance is strong, the motor has the perform of automatic smart protection and manage, which has a significantly smaller affect on the operation of the motor than the classic 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 hole) at the centre of the tail of the shaft, and an air hole at the shaft extension finish for installing a pneumatic clutch. The shaft of TMW series brushless synchronous motors is geared up with a coaxial rotating rectifier and rotating armature AC major exciter, which replaces the collector ring and brush framework of TDMK sequence motors to give excitation for the motor.
Stator: The stator frame is welded by steel plate, and the motor stator outlet is led by high-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 lower-reduction silicon metal 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 assist lengthen the service life. Making use of VPI all round dipping paint therapy, it has higher electrical overall performance, mechanical toughness, bonding overall performance, humidity resistance and thermal security.
The rotor magnetic pole core 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 according to the user’s specifications. The rotor help is manufactured of cast steel.
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 bottom plate is a metal plate welded construction, which is welded with a 20-30mm steel plate.
Adopt seat kind spherical sliding bearing. The bearings are insulated to prevent shaft currents. Use new lubricating oil and skinny-walled bearing alloy bushes, and established electromagnetic centerline symptoms.
TMW series brushless synchronous motors have little rotary rectifier discs, compact constructions and electrical connections. The set parts and the heat sink are built-in, which is dependable in procedure, reduced in failure rate, and hassle-free in set up and maintenance.
