4, specialized characteristics
4.1 The excitation, rectification, excitation management, de-excitation protection and other devices of the synchronous motor are put in on the rotor. The rectified power is equipped by the coaxial alternator, therefore reducing the slip ring and carbon brush system, generating the total framework compact and removing slippage. The spark produced by the speak to in between the ring and the carbon brush.
4.2 The use of new insulating supplies, semiconductor resources and insulation technologies, with super-powerful insulation stand up to voltage and anti-corona abilities.
four.3 The temperature rise margin is large. Below various working problems these kinds of as start off, overload, overexcitation, underexcitation, shutdown, etc., it can guarantee that the temperature increase of every element does not exceed eighty% of the corresponding team temperature. The motor adopts Class F insulation, and the temperature is evaluated according to the temperature increase limit of Class B insulation.
4.four The tE time price is long and the starting up time is brief. To make sure the security and trustworthiness of the motor, the tE time benefit of the motor is designed to be previously mentioned 9s, which is handy for customers to adjust and use.
4.5 The protection system is innovative and comprehensive.
four.5.1 Stator windings and bearings are geared up with temperature detection gadgets, which can check, alarm and excursion.
4.five.two Shutdown space heater with anti-condensation result (increased security airtight kind).
4.five.3 There is a purge gadget interface on the motor, and a purge pipe is developed within the motor to discharge the inner harmful gas ahead of the motor starts.
4.six The brushless excitation system adopts a coaxial integrated framework of rotating rectifier, rotating armature AC primary exciter and synchronous motor. It has automatic de-excitation security, computerized excitation at the very best time of polarity, and stage out of phase with load. The smart computerized handle function of the out-of-step protection has a substantial degree of steadiness and quick response efficiency. Moreover, when the voltage of the electricity source technique fluctuates instantaneously and there is an oscillation, or when the driven mechanical gear or approach has strong transient disturbance, the motor With automated clever defense and handle purpose, the affect on the operation of the motor is much scaled-down than that of the classic brushed synchronous motor.

structural form
five.1 The total structure of this collection of motors is a box structure, and the foundation, finish include, base plate, and many others. are welded by metal plates. The motor is an independent cavity, and the AC exciter and the rotating rectifier disc form another independent cavity.
five.two The magnetic materials of the motor and the exciter are manufactured of chilly-rolled silicon metal sheets with large magnetic permeability and minimal reduction. The damping strip and the magnetic pole main adopt a specific fixing strategy to stop beginning sparks all interior conductor connections, fasteners, supports and The screws on the rotating body have unfastened actions to guarantee firmness and dependability, and steer clear of sparks and arcs.
five.3 The stator winding adopts trustworthy anti-corona measures to increase the corona initiation voltage. The main motor and the AC exciter winding are dealt with with VPI as a whole dipping paint, which has higher electrical performance, mechanical toughness, insulation functionality, humidity resistance and thermal stability.
5.4 Adopt seat type spherical sliding bearing. The bearings are insulated to prevent shaft currents new lubricating oil and slim-walled bearing alloy tiles are used, and electromagnetic centerline indications are established.
5.five Rotating rectifier plate: The placement is little on the outside the house of the exciter, the electrical connectors, fixing elements and warmth sink are built-in, compact structure, reputable procedure, reduced failure fee, and hassle-free installation and servicing.
six. Circumstances of Use
six.one Voltage fluctuation: ±5%, (It can run at ±10% below the problem of 7.three in GB755)
six.two Frequency fluctuation: ±2%
six.3 The altitude does not exceed 1000m.
six.four The maximum ambient air temperature does not exceed +40ºC, and the minimum is 0ºC.
