XT-DGRXJ multistrand stator winding machine is specially designed for multiple wires and parallel coil winding applications.

• Capable of direct multi-wire concentrated winding instead of single heavy wire (over 1.5mm OD)
• High slot fill achieved by untwisting wire during winding cycle, enabling high motor output without changing stator OD
• Lower coil-end through direct winding, allowing motor downsizing
• Specifically designed for multiple wires and parallel coil winding in alternators, servo motors, and three-phase motors
• Special purpose controller with functions for arraying direction, winding start point, slow starting, slowing ending, sides stop, auto width, auto reset, etc.
• Significant material cost savings

This automatic motor stator needle winding machine is used to wind brushless DC motor inner stators. The BLDC stator coil winder adopts needle winding technology and can wind two stators simultaneously with two working stations.

When designing brushless motors, evaluating various motor parameters and components is crucial. The stator coil holds significant importance, with numerous requirements including stator outer diameter, inner diameter, stack thickness, number of wires and windings, wire diameter, number of turns, slot count, and slot distance.

• Larger wire diameters become challenging for winding machines - diameters exceeding 1.0mm pose difficulties
• Using multiple strands of thinner wire provides flexibility for easier winding and insertion into stator slots
• Reduces risk of single strand breakage leading to motor failure
• Improves heat dissipation through greater surface area
• Minimizes wire damage during winding process

• Skin Effect: Multiple wires provide stronger overcurrent capacity compared to single wires
• Maintenance: Using multiple wires reduces after-sales complications and repair challenges
