Fully automatic stator winding machines have certain standards for slot fill factor. Too high a fill factor can lead to winding difficulties and heat dissipation problems, while too low a fill factor can cause coil loosening. So, what are the requirements for slot fill factor in fully automatic stator winding machines? How can winding consistency be ensured? Let Vacuz give you a brief introduction below!
Ensuring winding consistency can be achieved through equipment precision control, a tension closed-loop system, and standardized processes.
Key Points for Slot Fill Rate Control
1. General Value Range: Maintain a balance range of 70%-75%. If higher fill rates are required, a matching heat dissipation design is necessary.
2. Optimized Fill Density: Select flat copper wire or variable cross-section flat copper wire for vertical winding. Control the copper wire forming profile within the range of 0.1-0.2mm.
3. Core Constraints: Equipment centering accuracy must be controlled to no more than 0.05mm, and insulation material thickness to no more than 0.1mm.
Path to Achieving Winding Consistency
Equipment Precision Control
1. Positioning Precision Control: Employ a 20-bit absolute encoder servo motor to ensure the wire spacing error is less than 0.01mm, reducing the probability of coil overlap.
2. Tension Closed-Loop Adjustment: Equipped with a tension sensor to adjust tension in real time, maintaining the copper wire tension within the 0.5-5N range, automatically matching parameters according to the wire diameter.
3. Speed Forward Algorithm: Decelerates in advance at corners to achieve a smooth winding transition and prevent conductor spillage.
Standardized Process Guarantee
1. Clamping Calibration Specification: Regularly checks the wear of the locating pins to ensure that the stator clamping concentricity deviation is less than 0.02mm.
2. Wire Pre-treatment Process: Uses wool felt to clean impurities from the conductor surface to reduce wire diameter fluctuations caused by friction.
