YBPT (63 ~~ 355) Explosion-proof frequency control three phase induction motor

YBPT (63 ~~ 355) Explosion-proof frequency control three phase induction motor
Product name:YBPT (63 ~~ 355) Explosion-proof frequency control three phase induction motor
Item:
Details:
YBPT63 355 flameproof VVVF three-phase asynchronous motor. Yes I YB2 series motors are based on the combination of the electromagnetic structure, processes, materials, etc. at home and abroad of new technologies and successfully developed new products, with the speed performance good, energy, temperature margin, long life, good performance, low noise, explosion-proof advanced structure, high reliability, use of easy maintenance, etc., can be used at home and abroad all kinds of conversion equipment and supporting facilities, contribute to energy saving and to achieve automatic control. Its rated power, rated speed and installation dimensions and YB2 series motors.
    
This series motors comply with GB755-2000 "Rotating electrical machines - Rating and performance industry standard JB/T7565.1-2004 YB2 series flameproof three phase asynchronous motor technology conditions (frame size H63 ~~ 355). Its explosion-proof performance in line with GB3836.1-2000 "explosive gas atmospheres - electrical equipment - Part 1: General requirements and GB3836.2-2000" explosive gas atmospheres - electrical equipment - Part 2: Flameproof "d" "provisions, respectively made flameproof ExdI, and ExdIIAT4, ExdIIBT4 (non-mining face) in the coal mine and factory IIA of Category IIB level, temperature group T1 ~ T4 group explosive gas environment dangerous places.
    
This series of motor enclosure protection rating of IP54 or IP55, cooling method is IC416.
    
This series motors can also be made of the Humid Tropics of type, dry tropical, outdoor and outdoor anti-middle-corrosion and outdoor hot and humid type.
Second, the conditions of use
    
Elevation: for at an altitude of over 1000 meters
    
Ambient air temperature: the lowest bit -15 ° C, ambient air, up to 35 ° C (coal mine) or 40 ℃ (factory) in the work environment.
    
The maximum relative humidity of the ambient air does not exceed 95% (when the temperature is 25 ℃) (coal mine) or the wettest, the monthly average relative humidity of 90%, while the monthly average minimum temperature is not higher than 25 ° C (factory).
    
Rated voltage: 380V
    
Rated frequency: 50Hz
    
Ways of working: continuous duty (S1)
    
FM: 2-pole frequency range (5) ~~ 60Hz, 4 pole above (5) ~ 100Hz, 3 (5) ~ 50Hz constant torque speed control, 50 ~ 100Hz constant power speed.
Three. Structure
   
Series flameproof YBPT VVVF three-phase asynchronous motor with computer-aided design, the motor can adapt to the SPWM and PWM inverter supply
Situation, made a special consideration in the design of the stator, rotor groove and the stator winding distribution patterns, in order to obtain a more appropriate inductor value, to suppress and reduce the adverse impact of the harmonic.
    
Motor electromagnetic load design considerations for a certain margin, both to ensure that the motor overload high frequencies can run in the low frequency to maintain constant torque output. In addition, the motor insulation system with Class F insulation system widely used international, reliable insulation and excellent performance. In structural design, the installation size with YB2 series motors the same convenient for user support.
   
Motor using a single axial fan forced ventilation, to ensure that the motor has a good cooling effect at different speed operation.
