Product Description

Product Description

QUAYDOTS & INNOMOTICS

Innomotics, formerly a wholly owned subsidiary of Siemens, was established as an independently operated company on July 1, 2023, following Siemens' strategic consolidation of its motor and large drive businesses. This restructuring brought together key product areas including frequency converters, low-voltage/high-voltage motors, and medium-voltage drive systems. Innomotics is headquartered in Nuremberg, Germany.

The new company integrates Siemens' former Large Drives Applications business unit along with parts of the Digital Industries division. With strong technological foundations and a global operational network, Innomotics continues to drive the development of high-efficiency drive solutions worldwide. In China, Innomotics operates five business entities and six R&D centers, employing approximately 3,500 people, and is recognized as a leading supplier of motors and drive systems in the Chinese market.

In January 2025, QUAYDOTS was officially granted distribution authorization for Innomotics' geared motor products in the East China region. With a significant pricing advantage in the competitive landscape and a commitment to professional technical support, QUAYDOTS offers customers efficient, reliable, and hassle-free product selection and application solutions.



INNOMOTICS provides the ideal solution for the hoisting mechanism of wire rope electric hoists.

The INNOMOTICS FDH series hoisting-dedicated geared motor is a specialized geared motor designed for the hoisting mechanism of wire rope electric hoists.
This series is developed and designed based on FEM standards and has undergone full-lifecycle enhanced fatigue testing.
The motor and drum device are arranged in parallel, resulting in a compact and rational overall structure.
