YBBP series of explosion-proof frequency control three-phase  asynchronous motor is our company on the basis of YB3 series motors,combined with the current  state,internal and external  electromagnetic structure,technology,materials and other aspects of the new technology and new product development. It  is characterized  by the use of motor and frequency converter,can achieve a wide range of smooth stepless speed regulation,in which  the frequency  rallge of 5-50Hz for constant torque converter,50-100Hz for constant power frequency conversion,motor with axial flow fan,ensure that the cooling effect at different  speeds. to ensure motor safety,normal operation.
The rotor of the motor is made of cast aluminum. After balance verification, the motor runs smoothly, with small vibration and low noise.This series motor power rating,installation size to meet the standard of the International Electrotechnical Commission(IEC) and the corresponding relationship with Germany DIN4267 standard is the same,is conducive to supporting the export of equipment and the introduction of equipment spreparts.This series of explosion-proof frequency control three-phase asynchronous motor and frequency conversion device constitute the speed control system and other speed control mode compared with energy-saving effect is remarkable,the speed performance is good ,the speed range is wide,with low noise,vibration,can be used with all kinds of domestic and foreign inverter,help to achieve automatic control.

Frame size: 80-355mm;
Output: 0.55-315kw;
Poles: 2-4-6-8-10;
protection class: IP55/IP56/IP65/IP66
 
ExdI, Ex d IIA T4 Gb, Ex d IIB T4 Gb

duty: S1,
Voltage: three phase 220-1000V (50hz or 60hz)
5-50hz(60hz): constant torque;
>50hz(60hz): constant output;

The motor can undergo overload of 160% at rated rotor torque for 1 minute.
The motor torque appears as smooth at lower speed and the motor runs without creep.

The motor can guarantee rated rotor torque output at frequency or 5hz by voltage rising of frequency converter device and not go so far as to be burned as heating.
