YBD3 series flame-proof variable-pole multi-speed three-phase asynchronous motors are fully enclosed self-fan-cooled squirrel-cage flame-proof three-phase asynchronous motors derived from YB2 series. This series of motors uses changing winding connections to change the poles of the motor. The number and output power are matched with the load characteristics of the mechanical equipment, simplifying its variable speed system and saving a lot of electric energy. There are three types of motor variable speed: two-speed, three-speed, and four-speed. There are 6 wiring bolts in the second-speed junction box, 9 wiring bolts in the three-speed junction box, and 12 wiring bolts in the four-speed junction box for users to use for variable speed and variable speed. The explosion-proof performance of YBD3 series flame-proof variable pole multi-speed three-phase asynchronous motors meets the requirements of GB3836.2-2000 “Electrical Equipment for Explosive Gas Atmosphere Part 2: Explosion-proof Type “d””, made ExdIIAT4 ExdIIBT4, suitable for The factory has hazardous locations where explosive gas mixtures of IIA, IIB, and temperature groups T1~T4 exist. The installation dimensions of YBD3 series explosion-proof multi-speed three-phase asynchronous motors are the same as YB2 series motors. YBD3 series explosion-proof multi-speed three-phase asynchronous motor body shell protection grade IP55. Cooling method IC411.
