· Features and application With the development of power electronic technology, AC VVVF adjustable speed systems are forging rapidly ahead. In order to meet the demands of the market, YTSP-series VVVF adjustable speed three-phase induction motors are designed and manufactured on the basis of extensive investigation and research. The basic technical requirements conform to the international IEC34-1 standard and the national GB755 standard. With the features of lower noise, lower vibration, wider speed range and better appearance, the motors can be matched with various frequency converters for good operation, conductive to energy saving and automatic control.
YTSP-series VVVF adjustable speed three-phase induction motors are specially designed for matching various IGBT pulse-width modulation frequency converters of high performance. Generally it is not necessary for them to be supplied with an external filter for operation.
YTSP-series VVVF adjustable speed three-phase induction motors, designed with computer aided technology, gather the advantages of similar motors at home and abroad. In order to apply the PWM supply, the stator, rotor slot and distribution of stator winding have been given special consideration to get a suitable inductance value for restraining and reducing adverse effects caused by time harmonic wave and a series of space harmonic waves produced by the former. Allowance for electromagnetic load has been taken into account to ensure the overload capability at high frequency and constant torque output at low frequency.
The impact of high carrier frequency of the PWM frequency converter with IGBT has been pondered in designing the insulation structure of the motors. Especially for the turn-to -turn insulation, in order to make it capable of being subjected to the severe ordeal resulting from the steep shock voltage applied repeatedly in the coil turns by the high voltage rise, special measures have been adopted to reinforce it. The tested values of interturn voltage endurance of the motors are much higher than the specified figures for AC motors in JB/Z346-89 standard.
In mechanical design, to be convenient for users, the mounting dimensions of YTSP-series motors are same as those of Y-series motors. YTSP-series motors have two types of cooling methods. One is IC411 (except YTSP400), with which the motors can be ensured to achieve the speed regulation of constant torque and output in a specified range of frequency (10-70Hz), and to operate for a long time under this condition while the temperature rise of the motor windings does not go beyond a prescribed limit. The other is IC416, that is, the forced ventilation by an independent axial blower is adopted, with which the motors can be guaranteed to operate for constant torque over a long period of time at the low speed (1-2Hz), with the temperature rise not exceeding a prescribed limit.
The frequency converter supplied power source is used during the ex-works test for all YTSP motors, so they conform with the actual operating conditions.
Therefore, the motors are recommended to various users and customers at home and abroad.· Performance The standard duty is the continuous duty (S1).When other duty type is adopted (such as S2, S3,….etc.),the corresponding relationship between the frame size and power in the technical data table may vary.
The rated voltage is 380V and the frequency is 50Hz.In accordance with the requirement of different ranges of speed regulation and power source for application, the ratings of voltage and frequency(such as 400V,440V,460V and 60Hz and so on)can be also redetermined. The motors of 400V rated voltage and △-connection, after changed into Y-connection, can be suitable for application of 690V mains Voltage.
The insulation of motors is of Class F or H. The insulation structure has the adaptability to high carrier frequency voltage supplied by frequency converter.
Speed can be adjusted in a wide range. IC411 motors can achieve the speed regulation with constant torque at 10~50Hz and with constant output at 50~70Hz.IC416 motors can, under the condition of open-loop U/f control, maintain torque constant during 3~50Hz and output constant during 50~100Hz (50~70Hz for 4P motors of frame size 355 and motors of frame size 400).And under the condition of vector control, speed range can be even expanded.
The overload capability of the motors is good, and the motors can be operated with the overload of 160% of rated torque within 1 minute.
Motors have good performance at low speed that torque is smooth and no crawling circumstance exists.
For the type of wire-connection, in general, motors of frame size 250 and below are of Y-connection, motors of frame size 280 and above are of △-connection. On special request, it can also break away from this division (such as motors of frame size 250 and below adopting △-connection, motors of frame size 280 and above adopting Y-connection).- TypeNominal PowerRated CurrentRated TorqueBreak Torque MultipleSlipWeight(kg)(kW)(A)(N.m)(Times)(%)IC416IC411YTSP90S-41.1372.55.51715YTSP90L-41.549.52725YTSP100L1-42.25.2144.23330YTSP100L2-437193734YTSP112M-44925.44440YTSP132S-45.511.5352.88072YTSP132M-47.515.547.79789YTSP160M-41122702.2125113YTSP160L-4152995.5140128YTSP180M-418.536.8117.11.8210190YTSP180L-42242140250230YTSP200L-43058190.91.5300275YTSP225S-43770235.51.4360330YTSP225M-44584286.4400370YTSP250M-455105350.1480450YTSP280S-475136477.41.1565530YTSP280M-490162572.9680645YTSP315S-4110200700.21.0870830YTSP315M1-4132235840.31025985YTSP315M2-41602801018.510951055YTSP315L-42003601273.311601120YTSP355M-42504401591.70.616001555YTSP355L-43155452005.518001755YTSP400L1-435561022600.82400YTSP400L2-440069025472700TypeNominal PowerRated CurrentRated TorqueBreak Torque MultipleSlipWeight(kg)(kW)(A)(N.m)(Times)(%)IC416IC411YTSP90S-60.752.57.12.56.51715YTSP90L-61.13.510.52725YTSP100L-61.54.414.35.33734YTSP112M-62.26.1215.14440YTSP132S-637.528.63.28072YTSP132M1-649.538.29284YTSP132M2-65.512.852.59789YTSP160M-67.51871.62.6125113YTSP160L-61126105140128YTSP180L-615301432.0250230YTSP200L1-618.5381761.6300275YTSP200L2-62245210320295YTSP225M-630552861.5400370YTSP250M-63772353480450YTSP280S-645854291.0565530YTSP280M-655104525680645YTSP315S-675139716.10.9870830YTSP315M1-690168859.41025985YTSP315M2-61102051050.310951055YTSP315L-6132245126011601120YTSP355M1-6160295152816001555YTSP355M2-6200370191016801635YTSP355L-62504452387.51.118001755YTSP400L1-631560030081.02600YTSP400L2-635566033902800TypeNominal PowerRated CurrentRated TorqueBreak Torque MultipleSlipWeight(kg)(kW)(A)(N.m)(Times)(%)IC416IC411YTSP132S-82.26.4282.548072YTSP132M-838.538.29284YTSP160M1-8410.850.93.511098YTSP160M2-85.514.570125113YTSP160L-87.51995.5140128YTSP180L-81126140.12.4250230YTSP200L-815351911.9300275YTSP225S-818.540235.61.6360335YTSP225M-82247280.1400375YTSP250M-83063382480455YTSP280S-83775471.11.3565530YTSP280M-84592573680645YTSP315S-855110700.30.9870830YTSP315M1-8751459551025985YTSP315M2-890182114610951055YTSP315L-81102201400.711601120YTSP355M1-81322651680.816001555YTSP355M2-81603202037.316801635YTSP355L-82003852546.718001755YTSP400L-825052031831.12800The date is listed in the Table are design values at 690V,50Hz and S1,only for reference when users select a required motor.
