JIUJU Four-Station Motor Magnetizer – A Revolutionary Solution to Enhance New Energy Vehicle Motor Manufacturing Efficiency

End-to-End Solution for Magnetization Automation

Four-station Motor Magnetizer: A Revolutionary Solution for New Energy Vehicle Motor Manufacturing Efficiency Improvement
Four-station Motor Magnetizer: A Revolutionary Solution for New Energy Vehicle Motor Manufacturing Efficiency Improvement

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:

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.

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

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.

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

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.

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.

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.

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.

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

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.

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.

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.

Four-station motor magnetizer is widely used in the following fields:

With the rapid development of the new energy vehicle industry, the demand for high performance permanent magnet motors is surging. Each new energy vehicle drive motor requires an average of four to six magnetizing processes, and the four-station magnetizer can significantly improve production efficiency and ensure the consistency and stability of motor performance.

The demand for miniature precision motors for consumer electronics products such as smartphones, tablet PCs and wearable devices continues to grow. The four-station magnetizer can meet the demand for flexible production of small batch and multiple varieties, and support quick changeover and quality control.

The demand for high-precision servo motors in industrial automation equipment, robotics, CNC machine tools and other fields is increasing. The high-precision control and stable performance of four-station magnetizers ensure the excellent performance of servo motors.

There is a growing demand for energy efficient motors for household appliances such as refrigerators, air conditioners and washing machines. Four-station magnetizer can improve production efficiency, reduce manufacturing costs and meet the demand for mass production.

With multiple stations working in parallel, the 4-station magnetizer is able to increase productivity by more than 300%, dramatically shortening the production cycle and increasing capacity utilization.

The integrated inspection system and intelligent quality control ensure consistent product quality and reduce the defective rate by more than 50%.

Automated operations and centralized control reduce reliance on operators and reduce labor costs by more than 60%.

Based on real-world applications, the payback period for a 4-station magnetizer is usually within 6-12 months, creating significant economic benefits for the company.
