YBBP series flameproof variable frequency speed regulation three-phase asynchronous motor is a fully enclosed, continuous working system of single-speed flameproof motor independently developed by our company, which is suitable for running in the speed regulation system powered by frequency converter. Anti-corona enameled wire is used in the motor design to adjust the electrical scheme and reduce the harmonic content, so that the motor has the advantages of energy saving, wide stepless speed range, low vibration and low noise, but also has the advantages of stable operation, no torque crawling phenomenon and long service life.

Commodity name: YBBP series explosion-proof variable frequency motor

The motor shall be made into explosion-proof type and explosion-proof type Ex d IIBT4 Gb according to the GB3836.1-2010 and GB3836.2-2010 requirements. It is widely used to provide driving power for equipment in various frequency conversion speed regulation systems in explosive atmosphere gas places.

Motor and frequency converter supporting the use of 5-50Hz to achieve constant torque speed regulation; 50-100Hz to achieve constant power speed regulation.

Can be equipped with an independent fan, so that the motor in the entire frequency range of the cooling effect is reliable and constant.

Main performance

● Rated power range: 0.37-315kW;

● Rated frequency: 50Hz;

● Rated voltage: 380/660V;

● Number of motor poles: 2, 4, 6;

● Standard protection grade: IP55;

● Insulation system: designed according to Class F (155 ℃), the temperature rise of the motor shall be assessed at 80K during rated output and direct power supply, and the temperature rise of the 2 and 4 poles of the 315 seat number and the motor of the 355 seat number shall be allowed to reach 105K;

● Motor cooling method: the standard cooling method is IC416 forced air cooling, but when the fan load is matched and the low frequency does not exceed 30Hz, IC411 self-fan cooling type can be selected;;

● Flameproof type of motor: Ex d IIB T4 Gb;

● Motors 315-355, 200 and above 2-pole motors are equipped with grease nozzles as standard, and 160 and above motors are optional;

●Casting material: cast iron (HT250);

● Standard installation structure type: IMB3, IMB5, IMB35, etc;

● The motor can choose PTC or PT100 thermistor for winding protection, and can also be equipped with winding temperature measuring device. For motors above 160, bearing temperature measuring device can be selected;

Special design: The appearance color of the motor can be adjusted according to customer requirements.

● When the motor is adjusting speed to high frequency, attention should be paid to: if it is a fan or pump load, the power of the load will increase when the frequency becomes higher. If it exceeds the rated power of the motor, the motor will be damaged;

● When the motor running speed exceeds the rated speed, the noise and vibration value will increase, and the bearing life will be shortened; the maximum safe speed of motor operation is as follows:
