YBD3 series change-pole multi-speed ex-proof three phase electric motor uses the simplex winding polarity reversal method to realize the speed transformation. Different poles offer relative speed.
YBD3 series motor are suitable for mechanical equipment which required speed regulation, mainly used in coal, oil and natural gas, petrochemical and chemical industries, usually used to drive pumps, fans, compressors and other transmission machinery.
We supply YBD3 series motors with Ex marking as Ex db Ⅰ AT4/BT4 Mb, Ex db Ⅱ AT4/BT4/CT4 Gb, which are intended for use in places with an explosive gas atmosphere other than mines susceptible to firedamp, A denotes a typical gas is propane, B means a typical gas is ethylene.
