1.12 groove stator,4-poles rotor,high efficiency with low weight ,low current ang low heat

2, Use wires of high temperature endurance,hand-wound,well-arranged wire,high slot fill factor.

3.Use Neodymium iron boron rare earth magnetic steel.front and bottom oversized high quality bearings life.

4.Dynamic balancing ensures rotation stability of each motor.

5.Use Kevlar for explosion protection

6.Parameters variable on customers  demand.
