Frequency conversion motricium & # (VIII) CCIII; 1 a, the influence of the frequency converter for general asynchronous motor, motor power, and the problem of temperature rise regardless of the method of frequency converter in operation have been different degree of harmonic voltage and current, make the motor in non-sinusoidal voltage, power flow operation. Ibi apparuit materiae ut iam in usum sine fluctus type PWM inverter quod est exemplum, ejus humilis harmonica radix est nulla, maior est in Reliquae Dampnaceae Frequency temporibus (aluminium) consummatio est Rotor Aeris (Aluminium), II Part Rotor Aeris (Aluminium) consumptio est Rotor Aeris (Aluminium) consumptio. Nam Asynchronous motor prope basi fluctus frequency correspondentes synchronae celeritate gyrationis, ita altior harrocinativa ad maiorem lapsus secans rotor post faciendo talea eventurum multum rotor damnum. Praeterea, etiam opus ad considerandum additional aeris damna ex cutis effectus. Haec damna faciet motor rated calor, potestas descendit, in output potestatem reducitur, ut generalis tres-phase asynchronous motor currit in inverter output non-sinusoidal potestate conditionibus, ad temperatus ~ X% ~ ~ ~ ~. 2 now small and medium frequency converter, motor insulation strength problem, a lot is to choose the PWM control method, its about several thousand to more than 10 KHZ carrier frequency, which makes the motor stator winding to withstand high voltage build-up rate, equivalent to impose great impulse voltage gradient on motor, the turn-to-turn insulation of the motor under relatively strict examination. Alia, produci per rectangulum SECURIS in PWM inverter impetus intentione superpositione intentione in motricium est currens, et pose a comminatione ad terram velit motricium, ad terram velocitate sub crebro. III, harmonic electro sonitus et sensatio cum eligens in inverter potestate copia generalis asynchronous motricium, potest facere electro, mechanica, evacuatione et alias elementa et strepitus facti magis universa. Variabilis frequency potentia copia continetur in omni momento harmonicae et motor electromagnetticum partem naturalis spatio harmonica faciunt ad invicem, varietate electro vibrationem vim. Cum electro fluctus frequency et motricium corporis inhaerens in oscillatione frequency, aut prope, erit resonatur resonatur, et crescat vocem. Quia motor operating frequency scale, wide celeritate mutatio magnus, omnes electro fluctus frequency difficile vitare inhaerens sensu variis components motricium frequency. IV, motor ut satus, braking aptet ad saepe quod selects in inverter potentia copia, motor potest sub humilis frequency et intentione non impulsum cucurrit modum ad celeri et varii, et mechanica compages et in system et mechanicas et accelerate in structuram et mechanica, et in motori et in motori, et mechanica compages et in motori et in motori, et mechanica compages et in motori, et mechanica componendis et in motori, et mechanica componendis et in motori, et in motori et accelerate et in structuram et accelerate et senescentis forsit. V, cum low celeritas refrigerationem problems primum, impedimentum de Asynchronous motricium infinita ambitiones, cum potentia frequency est imo, potestas damnum ex alto ordine harmonica. Secundo generali Asynchronous motricium, cum celeritas cadit et refrigerationem aeris volumine et celeritas ter unam partem reducitur, causare humili celeritas motor refrigerationem conditionibus deteriorare, temperatus ortum acriter addere, difficile ad consummare surge torque output. Special I Secundo, frequency conversionem motricium, electro consilio ad generalis asynchronous motricium, consilio munus prioritate parameter est overload facultatem, functio, potentia et potentia factor. Et frequency conversionem motricium, est propter discrimine lapsus ad potentiam frequency, potest directe satus in discrimine est quam ad amplio motricium in non sine facultatem et non potest esse quam ad improving potestate et non sine facultatem ad potentiam ad meliorem facultatem. Modi plerumque ut sequitur: I), ut quantum fieri potest, reductionem ad rotor resistentiam rotor. Decrescit in stator resistentia potest stillabunt fundamental aeris damnum, aeris damnum causatur ad compensare ad altiorem harmonicas addere II) pro habiti superiore harmonica current, debet esse oportet addere inductance motricium. Sed Rotor Slote Leakage resistentia est maior cutis effectus est etiam magnus, altior harmonica aeris damnum augeri. Ita motor Leakage resistentia MOLESTUS ad attendere ad duo vel Morethings advenit rationalitatem impediunt matching per totam celeritate temperatio scale. III) Frequency conversionem motricium de principalis magnetica circuitu est disposito in unsaturated conditione, consideratio altior harmonica harmonica est deepening magneticam circuitu Saturation, II id est considerare in humili frequency, ad amplio output intuens et properans ad amplio output intentione et propriis profectum output intentione. 2, structure design, structure design, the first is also considering non-sinusoidal power characteristics of variable frequency motor insulation structure and oscillation, the influence of the noise cooling method, etc, generally pay attention to the following questions: 1)Insulation class, generally for F or higher, strengthen the insulation and line turn insulation strength, especially considering the impact resistance voltage insulation ability. II) Oscillationis motricium, sonitus forsit, ut plene considerans motricium components et omnes rigiditatem, acriter progreditur inhaerens frequency, ne resonatur in omni vi fluctus. III) Refrigerant modum: coactus aer refrigerationem est plerumque lectus, pelagus motor refrigerationem fan cum independens motricium coegi. IV) Ad ne hastile current, extra facultatem CLX KW motricium debet eligere afferentem velit mensuras superiores. Primum est pronus ad asymmetric magneticam circuitu, potest etiam fieri potest hastile current, cum cetera altum frequency pondus quod fit cum current compositum ex effectis, in hastile et addo, et in tali adaquationes in tuto, ut saepe adoptavit in mensuram. V) Quod constans potentia variabilis frequency motor, cum celeritas ultra MMM / min, ut eligere specialis uncto, summus temperatus repugnant ad compensare ad temperatus ad afferaturam
