Machines for applying magnets to rotors
The application of magnets
The application of magnets is a process that is increasingly required in the assembly of electric motors. Magnets can be magnetised or non-magnetised, and are glued onto rotors with various types of adhesive. The adhesive can be applied, depending on the required productivity, with cartridges or tanks. The application of the magnets becomes a controlled and highly repeatable process. The process can be tightened up by measuring the amount of glue dosed, its position and thickness, achieving full control of the operation.
- Handling and application of flat or curved magnets.
- Handling and application of magnetised or non-magnetised magnets.
- Integration of advanced, high-precision dosing systems for dosing the exact amount of adhesive required.
- Polarity control system to avoid application/insertion errors.
- Rotors of all diameters can be processed with maximum precision, from small actuators to large motors.
- Different levels of automation available depending on the required productivity (e.g. robot systems).
- Maximum process control and repeatability.
- Flexibility to handle a significant production mix.
Standard magnet application machines.
Standard machine applying magnets in the production of brushless motors.
“Machine suitable for bonding non-magnetised permanent magnets for the production of brushless motor rotors. It allows the magnets to be applied to rotors of various sizes with a high degree of precision and to be applied at different angles and positions. The operator can control the correct functioning of all processing steps via the console.

Petal magnet application machines.
Magnet application machine for the production of brushless motors.
“Non-magnetised permanent magnet gluing machine for the production of medium and small batches of brushless motors.
- Fast piece change when operation is complete.
- Rapid rotor type variation.
Maintenance:
Almost absent.
Production times:
30 seconds on average per rotor.
Large batch magnet application machines
Magnet applicator on rotors for brushless motors, large batches.
Advantages
- Possibility of processing rotors with different dimensions.
- Processing 60 rotors per hour with the possibility of increasing performance by installing a CNC.
- Automatic CNC machining control.
- EEC safety regulations
Machine operation:
- Glue coating.
- Pressing and gluing magnets.
The machine consists of a solid steel base.
The positioning of the rotors in the two sub-stations is done by a five-axis manipulator equipped with a rotary gripper. This picks up the rotor from the “blanks” carriage and at the end of the machining process places it in the finished parts carriage. The operator via the console controls the correct functioning of each operation.
A less expensive PLC-controlled version with lower productivity is available on request.
