4.1 In principle, it shall use the failure mode of the drive motor (hereinafter
referred to as the motor), the components of the motor controller, and the
wiring between them to describe the failure.
the failure OR otherwise it cannot determine which component fails, it may
use the failure mode of higher level component (until to the drive motor or
motor controller) to conduct description.
Appendix A
(Normative)
Drive motor system failure mode
A.1 Damage failure mode
Damage failure modes mainly include.
- Fracture. Geometric surface separation with limited area. The location of
- Fragmentation. The phenomenon of parts becoming many irregularly
shaped fragments. The location of failure includes bearings, rotor splines
and so on.
- Cracks. Minor cracks on the surface or inside the component. The
location of failure includes controller shell, motor base, cover and so on.
- Fractures. Visible cracks in welds, sheet metal parts, and non-metallic
parts. The location of failure includes insulation board, wiring board,
cable and so on.
- Pitting. Spot erosion on the surface of the component. The position of
- Ablation. Damage to the surface of the component due to local melting.
The location of failure includes circuit breaker.
- Breakdown. Damage due to electrical discharge caused by the loss of
insulation of the insulator. The location of failure includes motor windings,
capacitors, power devices and so on.
- Deformation. the phenomenon of original shape change of components
under external force, such as the bending or torsional deformation of the
motor shaft, and the deformation of the controller housing.
- Indentation. Crevice marks on the surface of the component, such as
- Burning. All or partial function failure due to operating temperature
exceeding the allowable temperature of components for a certain period
- Gap deviation. The phenomenon that the function is affected by the
contact gap or fit clearance exceeding the specified value, such as the
gap deviation of contactor, bearing, and so on.
- Interference. The phenomenon of collision or abnormal friction between
moving parts, such as the interference between fan blades and wind
hood, speed sensor and tooth plate, motor stator and rotor, and so on.
- Performance offset. The instability of critical output, such as the
A.5 Blockage and leakage failure modes
Blockage and leakage failure modes mainly include.
- Blockage. The phenomenon that the fluid in the pipeline cannot flow OR
flow smoothly, such as the pipeline of the liquid-cooled motor and
controller.
- Leakage. T...
