JP calls on you to enhance the quality of your hub motors

PHZS-50 electric bicycle hub motor dedicated balancing machine

The unbalance of the hub motor is the root cause of the shaking, abnormal noise and bearing wear in electric bicycles.
The hub motor of electric bicycle has a high integration degree and the rotational speed is continuously increasing. Even a slight mass eccentricity will be amplified into severe vibration when rotating at high speed. “Dynamic unbalance testing” has become a key quality control step before the motor leaves the factory. Currently, well-known electric bicycle brands such as 'Yadea, 'LuYuan', and 'Ninebot' have all implemented strict unbalance testing for the hub motor to ensure the comfort and lifespan of the entire bicycle.
JP's PHZS-50 hub motor dedicated dynamic unbalance testing machine
Designed specifically for the batch inspection and repair scenarios of electric bicycle hub motors, it integrates "two-plane dynamic unbalance measurement", "PLC automatic control", and "data management and export", featuring stability, efficiency, and ease of operation.
Equipment composition
PHZS-50 includes:
- Measurement station
- Measurement system
- Electrical components
- Safety enclosure (optional)
Core advantages:
1. Dual-plane dynamic unbalance detection, completely eliminating unbalance
Simultaneously measures the amount and angle of the unbalance on both correction planes of the hub motor, supporting weight removal or weight addition correction modes. It meets the high-precision requirements of electric hub motors.
2. Stable and reliable, with a low error rate
The entire machine is controlled by Siemens PLC, equipped with high-quality sensors and drive components, ensuring good consistency in repeated measurements. It maintains an extremely low false alarm rate during continuous batch production.
3. Human-machine interface + data export
Equipped with an HMI touch screen, real-time displays parameters such as unbalance values, angles, and rotational speed. All measurement data can be exported via USB or Ethernet, facilitating integration into the MES system or for quality traceability.
4. Simple and efficient, cost-saving
The equipment has a compact structure, small footprint, short measurement cycle， and operators can get started easily after simple training.
5. Additional optional items
Optional items such as barcode scanning, automatic marking machine, and MES data upload.
JP has served the production lines of a number of leading automobile enterprises.
After years of refinement, JP balancing machines have been widely applied in the hub motor unbalance inspection processes of "Yadea, LuYuan, Ninebot, Aima" and their core motor suppliers. Our equipment can stand up to high-quality and high-standard production line inspections.
If the hub motors in your factory also need to meet higher quality standards, please feel free to contact us. We can customize a hub balance solution for you.
