Fully Automatic Winding Machine for Frameless Torque Motor Coils with Automatic Enamel Stripping

Robots are moving into more factories, warehouses, and even homes, and every robot joint depends on a compact, powerful motor. Frameless torque motors have become a popular choice for robot joints because they are lightweight, space-saving, and deliver high torque in a small package. Behind each of these motors is a precisely wound coil.

To support this fast-growing market, we have developed a fully automatic winding machine designed for frameless torque motor coils.


Bobbinless Air-Core Coils

Frameless torque motors often use bobbinless air-core coils. Without a bobbin to hold the wire, the coil must be wound tightly and formed accurately so it keeps its shape after it is removed from the tooling.

Our machine winds these coils automatically, producing neat, compact turns that are consistent from one coil to the next.


Long Lead Wires, Handled Automatically

Many frameless motor designs require long lead wires for connection inside the robot joint. Handling long leads by hand is slow and can easily damage the wire. This machine manages long leads as part of the automatic process, reducing manual work and helping protect the wire.


Built-In Automatic Enamel Stripping

Enamel must be removed from the lead ends before the coil can be connected. Traditionally, this is a separate manual step. Our machine integrates automatic enamel stripping into the winding process, so coils come off the machine ready for the next stage of production.


Combining winding and stripping in one machine helps manufacturers:

  • Save labor and floor space

  • Shorten production time per coil

  • Reduce quality issues caused by manual stripping


Designed for the Robotics Industry

This solution is well suited for manufacturers of:

  • Robot joint motors and actuators

  • Frameless torque motors

  • Other compact motors using air-core coils
