I. Overview
YBPT series high-voltage flameproof three-phase asynchronous motor with variable frequency speed regulation, frame size 560~710, is our company’s
Adapt to the development trend of high-voltage asynchronous motor variable frequency speed regulation technology, meet market demand, and absorb the best of similar motors at home and abroad
Advantages and computer optimized design, combined with our company’s decades of design and manufacture of high-voltage explosion-proof three-phase asynchronous electric
A new series of explosion-proof products developed based on the experience of the machine.
This series of motors uses computer-aided design technology to make the matching of the motor and the frequency converter more reasonable, and the motor efficiency
The design of high efficiency and power factor can reduce the capacity of the inverter and reduce the cost of the control system. Motor slot matching,
Special considerations have been made for slot shape and winding distribution to suppress and reduce the adverse effects of harmonics. Of each phase winding
The insulation of the first and last turns has been specially treated to ensure that the winding insulation does not break down under the action of the surge voltage peak. Electric motor
The electromagnetic load design leaves a certain margin, which can not only ensure the overload capacity of the motor at high frequency, but also can run at low frequency.
Maintain constant torque output.
This series of motors have the advantages of good frequency modulation performance, energy saving, low noise, low vibration, safe and reliable operation. Work
The rating and electrical performance are in line with the national standard GB755-2000 "Rating and Performance of Rotating Electrical Machines" and the International Electrotechnical
Committee (IEC) standard. The explosion-proof performance complies with GB3836.1-2000 "Electrical Equipment for Explosive Gas Atmosphere, Part 1
Part: General Requirements" GB3836.2-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 2 Explosion-proof Type "d""
Provisions. Can be made into ExdⅡAT4, ExdⅡBT4, ExdⅡCT4 type, power from 280kW~1600kW, number of poles
It is 2~8P, rated voltage 3kV, 3.3kV, 6kV, in line with the current development level of inverters, rated frequency 50Hz,
60Hz, frequency conversion range 20~60Hz.
The protection level of this series of motors is IP54, the cooling methods are IC511, IC516, and IC516 is equipped with internal circulation
The cooling method of forced ventilation outside the wind.
2. Structure description
The motor frame is welded with steel plate, with light weight, good rigidity and beautiful appearance.
The stator adopts built-in pressure structure, F-class insulation, and the stator and rotor punching pieces are made of high-quality cold-rolled silicon steel sheet 50W400.
The magnetic wire adopts polyimide double glass fiber high-quality rectangular copper wire, and the end is reliably fixed and bound, and adopts vacuum pressure immersion
Staining solvent-free paint process VPI treatment, so the motor has excellent and reliable insulation performance, good mechanical performance, and moisture resistance
Strong.
The squirrel cage rotor can be made into a cast aluminum rotor and a copper bar rotor. The cast aluminum rotor is made of centrifugal cast aluminum, which has good integrity and can run
Rely on: The copper bar rotor adopts advanced and reliable welding technology and is processed by the fastening process in the groove.
The bearing adopts rolling bearing or end cover spherical sliding bearing structure, the rolling bearing adopts three-bearing structure, and the shaft extension end
2
There are two bearings, one ball and one column. The column bearing carries the radial load, and the ball bearing plays a role in positioning to prevent axial string movement.
To withstand a certain axial force, there is a column bearing at the non-shaft extension end, and at the same time, there are oil injection and discharge devices at both ends of the motor, which can be set
Replace the grease regularly, and it can also be made into non-stop oil injection and drainage. The sliding bearing adopts the advanced structure of Renk Company, and the forced
Lubrication, to ensure the reliable operation of the motor at low speeds, and one end of the bearing is insulated to prevent shaft current generation, to ensure
The bearing bush does not produce electric corrosion.
The protection level of the main junction box is IP54, generally installed on the right side of the motor, looking at the motor shaft extension end, it can also be ordered
It is required to be installed on the left side of the motor. Grounding terminals are provided inside and outside the main junction box.
The motor is equipped with stator, bearing temperature measuring device, moisture-proof heater, and encoder can be added according to user requirements, effective
The user’s monitoring of the motor has been strengthened, and the safety has been greatly improved.
This series of motors can also be made into "W" outdoor type, "TH" hot and humid type, and "F1" and "F2" anti-corrosion type.
This series of motors are suitable for mechanical devices that require speed adjustment in explosive gas mixtures, such as water pumps, fans,
Compressor etc.
