Variable Speed Drives

Efficient Motor Control with Variable Speed Drives

Industrial variable speed drives (VSDs), also commonly known as variable frequency drives (VFDs), provide precise control of AC motor speed and torque while helping to improve energy efficiency and reduce operating costs. Ideal for applications including pumps, fans, conveyors, compressors, production machinery, and automation systems, LED Controls Ltd supplies a comprehensive range of AC drives for reliable motor control across demanding industrial applications.

By controlling the frequency and voltage supplied to an AC motor, variable speed drives allow motor speed to be matched to the actual requirements of the application. This provides greater control over machinery while helping to reduce unnecessary energy consumption, mechanical stress, and motor wear compared with applications where motors continuously operate at full speed.

Designed for flexible industrial motor control, our variable speed drive solutions offer:

  • Energy-Efficient Motor Control: Adjust motor speed to match application demand, helping reduce unnecessary electricity consumption and operating costs.
  • Precise Speed & Torque Control: Provides accurate control over motor performance for pumps, fans, conveyors, compressors, machinery, and automated processes.
  • Flexible Industrial Integration: Choose from compact micro drives, general-purpose inverters, and high-performance industrial drives for a wide variety of motor control applications.

LED Controls Ltd supplies genuine variable speed drives from leading manufacturers with full manufacturer warranty and expert technical support. Whether you are upgrading existing machinery or specifying a new installation, we can help you select the correct drive based on motor type, power (kW), supply voltage, current rating, control requirements, and application. Explore our complete motor control and motion range, including soft starters, or contact our technical team for drive selection and application advice.
