Frequency controller for winch applications

A characteristic of a winch is that there must always be good control over the load, even at low speeds. The most common applications for a winch include lifting, pulling, controlled unwinding, maintaining constant tension on the cable, and positioning the load.

Variable-frequency drive for winch applications

Each application has its own requirements for the drive system, including the variable-frequency drive. A characteristic of a winch is that there must always be good control over the load, even at low speeds. A variable-frequency drive with Vector Control regulation is indeed essential in this case.

When performing relatively simple tasks such as lifting or pulling the load at multiple speeds, a Vector Control system is more than sufficient to achieve a well-functioning drive system that is also straightforward in its design.

For more advanced winch applications, it is necessary to provide the variable-frequency drive with precise information about the motor’s behavior. With this, advanced applications such as maintaining constant tension on the cable or 4-quadrant operation, including precise load control at 0Hz (standstill), can be achieved without any issues.
