Article editor：NOYUWhen selecting and matching a brushless motor external rotor winding machine, it is crucial to comprehensively consider the motor specifications, winding technology, machine performance and actual production requirements. Below is a detailed purchasing guide provided by NOYU for you from multiple dimensions such as the category, core configuration, technical points and performance standards of the winding machine:
I. Selection of Winding Machine Categories
1. Flying fork type winding machine
Application scenario : Designed for external rotor stator with notch outward, common in fields such as model aircraft motors, UAV motors and pan-tilt motors.
Pros : Known for high-speed winding, excellent efficiency, perfect for mass production environments.
Configuration recommendations :
Ordinary : stepper motor is used, which is suitable for scenarios with low wiring accuracy requirements.
Precision : Equipped with servo motors to ensure constant winding tension and regular wiring to meet high accuracy requirements.
2. Needle winding machine
Application scenario : Although not a typical application of outer rotor, it is suitable for some special designed notch inward stator.
Features: High precision winding, but relatively slow speed, suitable for small batch or high precision product production.
Ii. Core Configuration and Detail Control
1. Drive system :
Stepper motor : cost-effective for low-speed, low-precision operations.
Servo motor : Provides high precision, high response performance, suitable for high-speed, high-precision winding needs.
Direct drive motor : No reduction mechanism, high transmission efficiency, suitable for high-speed winding (such as speed requirements more than 5000 RPM).
2. Control System :
PLC control : stable and reliable, supporting multi-axis linkage, suitable for complex winding process.
Motion controller : Realize high-precision trajectory control, suitable for difficult processes such as multi-line parallel winding and irregular winding.
Human-machine interface : intuitive operation, supporting parameter setting, fault diagnosis and production data recording.
3. Mechanical structure :
Spindle accuracy : Spindle runout is required to be less than 0.01mm to ensure concentricity of winding.
4. Nozzle design :
Ceramic or diamond tip : wear-resistant, high temperature resistant, suitable for high-speed winding.
Adjustable mouth Angle : adapt to different groove types and winding directions.
5. Tension Control system :
Magnetic powder brake : Tension stable, suitable for thin wire diameter (such as 0.05mm below).
Servo tensioner : provides high precision tension control, suitable for thick wire diameters (e.g., 1.0mm and above).
6. Wiring mechanism :
Precision guide : Ensure smooth wiring, avoid jumpers and overlapping wires.
Synchronous belt drive : low noise, high precision, suitable for high-speed wiring.
Routing algorithm : Supports multiple routing methods, such as spiral, cross, etc., to optimize the coil fill rate.
Iii. Technical Highlights and Performance Standards
1. Winding speed and accuracy :
Speed : According to the wire diameter and groove type selection, such as 0.2mm wire diameter up to 1500 RPM or more.
Accuracy : The error of the winding position is less than ±0.05mm, and the error of the number of turns is less than ±1 turn.
2. Applicable wire diameter range :
Thin wire diameter : 0.03mm~0.2mm, need to be equipped with high precision line nozzle and tension control system.
Thick wire diameter : 0.2mm~2.0mm, large torque spindle and wear-resistant wire nozzle are required.
3. Multi-line and winding ability :
Number of wires : 2~16 wires can be wrapped in parallel, requiring independent tension control and synchronous wiring.
Insulation treatment : When winding, it is necessary to add insulating paper or coating insulating paint between the lines to prevent short circuits.
4. Level of automation :
Automatic loading and unloading : improve productivity and reduce manual intervention.
Automatic mold change : fast switch between different specifications of the stator, adapt to multi-variety production.
Quality inspection : Integrate functions such as turn detection and broken line detection to ensure product consistency.
Four. Matching of Production demands
1. Capacity demand :
Small batch : Choose single or double station winding machine, flexible adjustment process.
Large batch sizes : Choose multiple stations (e.g., 4 stations, 6 stations) or fully automated production lines to increase efficiency.
2. Product diversity :
Universal winding machine : suitable for groovetype, wire diameter changes little product.
Special type winding machine : Customized for specific products, such as high-speed motors, micro motors, etc.
3. Cost Budget :
Economy : Stepper motor +PLC control, suitable for startups or low cost needs.
High-end model : servo motor + motion controller, suitable for high precision, high value-added products.
V. Brand and Supplier Recommendations
1. International Brand : Leading technology, applicable to the high-end market.
2. Domestic brands : cost-effective, perfect after-sales service.
Vi. Common Problems and Solutions
1. Damaged wire, broken wire : check the wear of the wire nozzle, adjust the tension parameters, and optimize the winding speed.
2. Irregular wiring : Calibrate the wiring mechanism, adjust the Angle of the wire nozzle, and check the spindle runout.
3. Low winding efficiency : Upgrade the drive system and optimize the winding algorithm to reduce non-productive time.
When choosing a brushless motor external rotor winding machine, it is necessary to comprehensively consider the motor specifications (slot type, wire diameter, number of turns), production requirements (production capacity, precision) and budget. Prefer equipment with high-precision drives, stable control systems and flexible wiring mechanisms, and pay attention to the technical support and after-sales service capabilities of suppliers.
