Headline: Achieving the Perfect Balance: The Science of Rotor-to-Shaft Press-fitting

In the world of high-speed motors, the assembly of the Rotor Sub-assembly (Shaft + Rotor Core) is a critical stage where precision meets performance. A minor deviation can lead to noise, vibration, or even total motor failure.


At Leetx, we focus on solving the three pillars of rotor assembly: 

1.Reliable Torque Transmission: Achieving the optimal interference window. Too loose? You face slippage. Too tight? You risk cracking core laminations or damaging magnets. 

2.Rotational Accuracy: Our systems ensure perfect coaxiality and run-out control, eliminating the roots of vibration and inefficiency. 

3.Precise Axial Positioning: Using displacement-priority with force-monitoring closed-loop control, we guarantee the exact air gap and end clearance required for peak motor efficiency.


With our Servo Press System, we don't just "press"—we monitor every micron and Newton-meter in real-time.
