Case Study of Introducing the Optimal Motor for Adjusting Torque Control and Tension

[Pushing and Tightening] Limits the Generated Torque, Preventing Damage to the Load

Typical Application Examples

Recommended Motors

Torque Motor
Setting the torque value directly, prevents damage caused by over-tightening. A simple system configuration can be built for a reasonable price.

Brushless Motor/αSTEP/Servo Motor
Setting the torque limiting value (torque limit), prevents damage due to over-tightening.Since the signal is output when the set torque limiting value is reached, it can be used as a trigger for the next operation. In addition, the αSTEP AZ Series is compatible with a variety of industrial networks, including EtherNet/IP.

*If a 40 W torque motor is required, please refer to Pairing with a power controller (TMP-1)

Typical Application Examples

Recommended Motors

Torque Motor
Motors can generate a braking force (reverse-phase brake) when rotated in the opposite direction to the motor rotation direction by an external force, etc. By using a torque motor on the unwinding side of the load, winding can be achieved while maintaining the appropriate tension. Also, since they do not wear out, there is no need for brake maintenance.

[Brushless Motor/Servo Motor]
This can be used as a brake to adjust the tension by limiting the generated torque, and rotating the motor in the opposite direction of the winding side. If the load is too heavy, it can also be used by rotating it in the same direction as the feed direction to assist in starting.

• For continuous regeneration operation, use a regeneration resistor (sold separately)

Recommended Motors

Torque Motor
The torque and speed required of the motor changes as the winding diameter changes, as shown in the table below. Torque motors have suitable characteristics for this change (sloping characteristics), making them ideal for winding applications.

[Servo Motor NX Series]
The tension control mode, in which the material thickness, initial diameter, and final diameter are set as parameters, allows highly accurate winding to be performed without the use of detectors or control devices.
