6. Rich and flexible external interface design: support Modbus TCP, Canbus, Profibus DP and other vertical, while retaining multiple dry contact transmission
Working system and ventilation mode
This series of motor rating is based on continuous working system (S1).
This series of motors adopt forced ventilation (with fan or pipe ventilation, air volume is 130 m/min.)
Main electrical performance
The characteristics of the motor are the variable frequency characteristics under the power supply of the converter. The motor operates at constant torque below the rated frequency, and operates at constant power from the rated frequency to the highest operating frequency.
The motor has a capacity of 1.5 times the rated torque for 1.5min at constant torque operation.
The motor can run alone or in parallel.
Working conditions
The motor shall be rated for operation under the following environmental conditions
Altitude not exceeding 1200m;
The maximum ambient temperature is 40 ℃;
Minimum ambient temperature -20 ℃;
Air relative humidity: the wettest month average maximum relative humidity of 90% (the month average minimum humidity of 25%).
YAFS series increased safety variable frequency asynchronous motor is a squirrel cage variable frequency speed asynchronous motor developed by our company to meet the needs of the market.
• The motor base is a steel plate welded structure with high mechanical structural strength;
• The rotor squirrel cage is a welded structure, using advanced welding methods, with high reliability;
• In order to meet the requirements of the inverter power supply, the corona-resistant insulation structure is adopted;
• The motor stator and rotor are all vacuum pressure impregnated and roasted;
• The motor has the advantages of large torque, wide constant power speed range, high efficiency, good versatility, maintenance-free, etc., and has a high overload capacity;
• It can be used with all kinds of voltage type frequency conversion devices at home and abroad, which is helpful for energy saving and automatic control;
• The motor has reliable explosion-proof performance, and the junction box is equipped with heater, air pressure switch and auxiliary explosion-proof button switch.
• The protection level of the motor shell is IP44 (solid and splash-proof with a protection diameter greater than 1mm), and the protection level of the junction box is IP54 (dustproof and splash-proof structure), which is suitable for places containing explosive gas mixture II and temperature group T3.
• The position of this series motor junction box, the standard type is from the drive end to see the right side (I. e. right outgoing line), can also be made on the left side (I. e. left outgoing line).
• The motor can be used for various pump loads and as a drag motor for AC drive systems. Especially suitable for oil rig rotary table, drawworks, mud pump and other equipment.
