YBBP frequency conversion explosion-proof motor introduction

YBBP series variable frequency speed control three-phase asynchronous explosion-proof motor is a new generation of explosion-proof variable frequency speed control motor developed on the basis of introducing foreign advanced technology and summing up our factory's years of experience in producing variable frequency motors to meet the needs of the market. In terms of electromagnetic design, the stator and rotor slot shapes, winding patterns, and connection methods have been adjusted to make them adapt to the condition of the inverter power supply, and to ensure the overload capacity of the motor at high frequencies, but also Keep constant torque output at low frequency. In terms of structural design, except for the length dimension, the installation dimensions are the same as the YB2 series motors, and the other external dimensions are also the same as the YB2 series motors. The interchangeability is strong and it is convenient for users to use together. This series of motors adopts independent axial flow fan for forced ventilation to ensure that the motor has a good cooling effect in the entire frequency range, and the temperature rise does not exceed the specified value.

Features and use places of YBBP frequency conversion explosion-proof motor

Compared with other speed control methods, the speed control system composed of this series of variable frequency speed control three-phase asynchronous motors and frequency conversion devices has significant energy saving effect, good speed control performance, wide speed control range, low noise and low vibration, and can be compared with domestic The matching features of various external inverters can be widely used in light industry, textile, chemical, metallurgical, machine tool and other industries for constant torque and constant power speed regulation occasions and energy-saving speed regulation of fans and water pumps, which is helpful to realize Automatic control of speed control system.

YBBP frequency conversion explosion-proof motor regulations and use environment

The explosion-proof performance of this series of motors meets the requirements of GB3836.1-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 1: General Requirements" and GB3836.2-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 2: Flameproof "d"" regulations , Also in line with IEC79-1,

According to BS4683 and EN50018, it is made into explosion-proof type. The explosion-proof marks are ExdI, ExdIIAT4, ExdIIBT4, which are suitable for places where explosive gas mixtures exist.

　　 ExdI is applicable to the non-excavation working face environment of coal mines where explosive mixtures of methane or coal dust exist.

　　 ExdIIAT4 is suitable for use in factories with Class II Class A, and the temperature group is the environment where explosive gas mixtures of T1, T2, T3 and T4 exist.

　　 ExdIIBT4 is suitable for use in factories with Class II Class B, and the temperature group is the environment where explosive gas mixtures of T1, T2, T3 and T4 exist.

ExdIICT4 is suitable for use in factories with Class II and Class C, and the temperature group is the environment where explosive gas mixtures of T1, T2, T3 and T4 exist

Structure Design of YBBP Frequency Conversion Explosion-proof Motor

When designing the structure, it is mainly to consider the influence of the non-sinusoidal power supply characteristics on the insulation structure, vibration, and noise cooling methods of the variable frequency motor. Generally, the following issues should be paid attention to:

1) Insulation grade, generally F grade or higher, strengthen the insulation to ground and the insulation strength of the turns, and especially consider the ability of the insulation to withstand impulse voltage.

2) For the vibration and noise of the motor, it is necessary to fully consider the rigidity of the motor components and the whole, and try to increase its natural frequency to avoid resonance with various force waves.

3) Cooling method: Forced ventilation cooling is generally used, that is, the main motor cooling fan is driven by an independent motor.

4) Measures to prevent shaft currents, bearing insulation measures should be adopted for motors with a capacity exceeding 160KW. The main reason is that the asymmetry of the magnetic circuit is easy to occur, and the shaft current is also generated. When the currents generated by other high frequency components work together, the shaft current will greatly increase, resulting in damage to the bearing, so generally insulation measures must be taken.

5) For constant power variable frequency motors, when the speed exceeds 3000/min, special high-temperature-resistant grease should be used to compensate for the temperature rise of the bearing
