What spare parts are required for the motor rotor end plate commutator integrated machine, and how should inventory be managed?

The following are some suggestions for spare parts and inventory management for the motor rotor end plate commutator integrated machine:

Spare parts:

1、mold: as a key component directly involved in the pressure end plate and commutator, you need to prepare a certain number of molds for replacement and maintenance.

2、 end plate: as the main processing object of the press end plate machine, need to prepare sufficient end plate according to the production demand.

3、Commutator: also need to prepare enough commutator according to the production demand.

Safeguard inventory settings:

•  Quantify the uncertainty of demand: First, it is necessary to quantify the uncertainty of demand, that is, the accuracy of the forecast and the error between the actual demand and the forecast. In mathematical statistics, we use the term “standard deviation” to quantify the uncertainty of demand.

• Quantifying supply uncertainty: Consider supply uncertainty, such as supplier lead times and reliability, which can be assessed through historical data and supplier communication.

• lRequirement of Availability: Based on the service level requirement, for example, it is desired to not run out of stock 95% of the time, corresponding to a z-value (quantile of standard normal distribution) of 1.65, which can be used to calculate the guaranteed inventory.

•  Safeguarded Stock Calculation Formula: The safeguarded stock can be calculated by the following formula: SS = z * SQRT(σd^2 * μL + σL^2 * μd^2), where SS is the safeguarded stock, z is the z-value corresponding to the service level, σd is the standard deviation of the demand, μL is the mean of the supply cycle, σL is the standard deviation of the supply, μd is the mean of the demand.

•  Regular Inventory: Regularly conduct all inventory counts of the inventory to ensure that the accounts are in line with the actual situation and to avoid blind increase or decrease of the inventory.

•  Reasonable structure: According to the product characteristics and market demand, the inventory structure is reasonably configured to reduce the slow-moving inventory.

•  Informatization management: Improve the automation and intelligence of inventory management with the help of informatization technology and management tools.

Through the above methods, it is possible to set a reasonable safety stock for motor rotor end plate commutator integrated machines to ensure production continuity and timely supply of spare parts.
