YD Series Variable Pole Multi-speed Three-phase Asynchronous Motors are one of the main series products deriving from three phase series. This kind of motor can change rotational speed as load status, to properly match the demands of power and simplify transmission system. YD series motors are equivalent to foreign standard; therefore they are matching the specification for export as well as import.
