What spare parts are needed for a manual stator slot wedge machine for brushless motor motors and how should I set up a guaranteed stock?

I. Spare parts demand list

1、Core wearing parts:

Slot wedge: need to choose the specifications according to the motor model (such as width 3-18mm, thickness 1.5-5mm), common materials for epoxy resin (such as 3240, 3940) or magnetic materials (need to prevent loosening design).

Insulating materials: including grooved insulating paper (thickness ≤ 0.3mm), semiconductor pads, weftless glass tape, etc., for corona protection and enhanced insulation.

Transmission components: gears, chains, belts, etc., which need to be checked regularly for wear and tear.

Electrical components: control boards, switches, buttons, contactors, etc.

2, auxiliary accessories:

Bearings: make sure they are well lubricated and replaced regularly.

Fasteners: screws, spacers, etc. to prevent loosening.

Tools consumables: such as tying lines, grease, cleaning tools.

3、Special spare parts:

Original customized parts: such as specific models of stator and rotor components, which need to be purchased directly with the manufacturer.

Second, to protect the inventory setup method

1、Classification management (ABC analysis method):

Class A (critical spare parts): groove wedges, insulation materials, bearings (accounting for 65% of the inventory cost), the need for high security inventory, regular monitoring.

Class B (less important): transmission gears, electrical switches, medium inventory.

Class C (low-value consumable): screws, tying wires, purchased on demand.

2. Calculation formula:

Safeguard stock = average daily consumption × (procurement cycle + delivery time) + buffer stock

Example: If the average daily consumption of 10 groove wedges, the procurement cycle of 5 days, the supplier delivery period of 3 days, buffer stock of 20, then the guaranteed stock = 10 × (5 + 3) + 20 = 100.

3, dynamic adjustment factors:

Frequency of use: high-frequency replacement parts (such as groove wedge) to improve inventory.

Procurement cycle: imported or customized parts (such as the original rotor) to extend the stocking cycle.

Supplier reliability: choose a stable supplier to shorten the delivery time.

Cost control: high-priced parts (such as control boards) using JIT (just-in-time) procurement.

4, management tools:

The use of inventory management systems (such as warehouse management king) real-time monitoring of inventory levels, set up an early warning mechanism.

Regular inventory to avoid stagnant material.

Third, the operation of the recommendations

1, spare parts procurement:

Bulk purchase of general-purpose parts through Alibaba, Jingdong and other platforms.

Special specifications slot wedge and original parts need to sign a long-term agreement with the designated supplier.

2、Inventory maintenance:

Dry and ventilated environment for storage, to avoid moisture of insulating materials.

Magnetic slot wedges need to be checked regularly for wire fixing.

3、Regular assessment:

Quarterly analysis of spare parts consumption data to optimize the parameters of the protection of inventory.

Equipment with a high failure rate (such as motors in high-temperature environments) requires shorter inspection cycles.

Through the above strategies, we can ensure the timeliness of spare parts supply, and at the same time reduce the inventory cost to guarantee the stable operation of the equipment.
