Industry background and challenges

Under the current background of rapid development of intelligent manufacturing and new energy industry, motor manufacturing enterprises are facing unprecedented opportunities and challenges. According to authoritative market data, in 2024, China'sAutomatic magnetizationThe market size has reached RMB 3.86 billion and is expected to exceed RMB 4.5 billion by 2025, with a CAGR of around 14.3%. Among them, the proportion of new energy vehicles has reached 32.5%, becoming the largest application market.

However, the traditional motor manufacturing process ofmagnetization sessionThere are still many pain points:

Inefficient production

Conventional single-station or double-station magnetizing equipment adopts the step-by-step operation mode of "loading → magnetizing → discharging → transferring → detecting", and at the end of each step, it is necessary to wait for the equipment to reset in order to start the next process, and a lot of time is wasted in the waiting process.

Unstable product quality

Manual operation and step-by-step inspection easily lead to product quality fluctuation and high defective product rate, which seriously affects the production efficiency.

Complexity of changeover adjustments

When replacing workpieces with different motor specifications, it is necessary to re-tune the magnetization parameters and replace the positioning tooling, which is time-consuming and affects the continuity of production.

High labor costs

Traditional equipment requires professional operators to monitor and adjust, and labor costs account for a relatively large proportion.

Solution: Four-station motor magnetizer

In response to the above industry pain points, we have launched a revolutionary four-station motor magnetizer solution. This equipment adopts advanced multi-station synchronization technology, and by reconfiguring the operation logic, it deeply integrates the magnetization and inspection links, which fundamentally solves the efficiency bottleneck problem of traditional equipment.

Core Technology Advantage

Multi-station parallel synergy technology

four-stationMagnetizerThe core innovation lies in the fact that the four workstations form a "parallel and synergistic" chain of operations rather than a single module that operates independently. Each station corresponds to a fixed process node:

• Workstation 1: Responsible for loading and accurate positioning of workpieces.
• Workstation 2: Focused magnetizing operation to ensure uniform magnetic field strength
• Stations III: Simultaneous magnetic performance testing for real-time quality monitoring
• Stations IV: Completion of qualified workpiece discharging and realization of automated flow

When Workstation 2 starts the magnetization operation, Workstation 1 has already completed the positioning of the next workpiece, and Workstation 3 is synchronized with the detection of the previous magnetized workpiece. The four links are seamlessly connected, completely eliminating the waiting time in the traditional process.

Intelligent Inspection and Quality Control

In terms of simplifying the inspection process, this technology breaks the traditional mode of "separation of magnetization and inspection". The four-station magnetizer directly integrates the detection module into station three, so that the workpieces can enter the detection process after magnetization without transferring, following the flow of stations.

Detecting unqualified workpieces, it will mark in real time and suspend the subsequent operation of the corresponding workstation, which is convenient for operators to troubleshoot the problem in time. This design avoids the flow of unqualified workpieces into the next loop and reduces unnecessary rework costs.

Quick changeover and flexible production

Multi-station synchronization technology also significantly simplifies the specification switching process. When replacing a motor workpiece with a different specification, the traditional magnetizer needs to re-tune the magnetization parameters and replace the positioning tooling, which is time-consuming; while the four-station magnetizer only needs to replace the adapted station positioning components for different specification workpieces, and the core magnetization and detection parameters can be quickly called up through the equipment's preset program without repeated adjustments.

Centralized control and intelligent management

The centralized control system of the equipment can manage the operation status of the four stations in a unified way, so that the operator does not need to monitor the magnetization and inspection equipment separately, but only needs to check the progress and inspection results of each station through the console, which greatly reduces the complexity of the operation.

System Support:

• Real-time data monitoring and display
• Historical data traceability and analysis
• Fault self-diagnosis and alarm
• Remote O&M and Parameter Optimization

Technical principles and working mechanisms

The four-station motor magnetizer is based on JiuJi's capacitive magnetizing technology, combined with modern control theory and industrial automation technology to realize efficient and accurate magnetizing operation.

Principle of Magnetization Technology

The equipment adopts high-voltage capacitor energy storage technology to release a strong pulse current in a short period of time to magnetize magnetic materials. The working voltage is generally concentrated in the range of 1.5kV to 4kV, with a typical value of 3kV, and the energy storage capacity ranges from 500 Joules to 64,000 Joules, which can satisfy the magnetization requirements of different specifications of motor magnets.

Multi-station synergy mechanism

Precise synergy of the four stations is achieved by means of a sophisticated servo control system and synchronized triggering technology:

1. Synchronous trigger controlMulti-channel synchronized triggering technology, supporting up to 16 channels of independent control, with inter-channel synchronization error of less than 50 nanoseconds.
2. Precision positioning systemRepeatability: Repeatability better than ±0.05mm ensures the accuracy of the magnetization position.
3. Real-time feedback adjustmentEquipped with high-precision sensors, real-time monitoring of magnetic field strength and waveforms during the magnetization process.
