Variable Speed Drives (VSD) and Soft Starters

Enhanced Motor Control Solutions: Soft Starters and Variable Speed Drives (VSD).

Soft Starters

Soft Starters help reduce inrush current and limit torque during startup, benefiting your equipment by improving motor performance and longevity while managing electricity consumption costs. They are ideal for applications such as pumps, fans, compressors, conveyors, crushers, and ball mills.

By gradually increasing the voltage supplied to the motor, soft starters ensure a smooth and controlled acceleration to full speed. This process significantly benefits your equipment by:

• Improving Motor Performance and Longevity: Reducing mechanical stress on the motor and connected equipment during startup helps extend the lifespan of your machinery.
• Managing Electricity Consumption Costs: By controlling the initial surge of current, soft starters help lower energy consumption and reduce operational costs.
• Enhancing System Reliability: Soft starters minimise the risk of electrical and mechanical failures, ensuring more reliable operation.

Soft starters are ideal for a variety of applications, including:

• Pumps: Ensuring smooth operation and preventing water hammer effects.
• Fans: Reducing mechanical stress and noise during startup.
• Compressors: Protecting against sudden pressure surges.
• Conveyors: Providing controlled acceleration to prevent material spillage.
• Crushers: Minimizing mechanical shock and wear.
• Ball Mills: Ensuring consistent and controlled operation.

Variable Speed Drivers (VSD)

Variable Speed Drives (VSD) offer advanced features, including the ability to control and change the operating speed of your application.

VSDs are preferred for equipment that requires speed variation. Kenshaw can modify motors for VSD operation, including fitting insulated bearings, earth brushes, and internal shaft grounding rings.

VSDs are suitable for various applications, including:

• HVAC Systems: Optimising airflow and temperature control.
• Pumps: Adjusting flow rates to match demand, reducing energy use.
• Conveyors: Controlling speed for precise material handling.
• Mixers and Agitators: Ensuring consistent mixing speeds.
• Centrifuges: Providing precise speed control for separation processes.

By integrating soft starters and variable speed drives into your motor control systems, you can achieve significant improvements in performance, efficiency, and reliability. Kenshaw Electrical offers expert solutions and modifications to ensure your equipment operates at its best.
