Details of sensor placement.

Types of sensors	Test Point	Position number
Three-axis vibration accelerometer	Bearing housing X-direction	S1
	Bearing housing Y-direction	S2
	Bearing housing Z-direction	S3
Uniaxial vibration accelerometer	Imported flange Y-direction	S4
Uniaxial vibration accelerometer	Imported flange Z-direction	S5
Uniaxial vibration accelerometer	Export flange X-direction	S6
Uniaxial vibration accelerometer	Export flange Y-direction	S7
Uniaxial vibration accelerometer	Z-direction of the motor base	S8

Note:The X direction is defined as the axial direction, the Y direction as the horizontal radial direction, and the Z direction as the vertical direction.
