Variable speed drives - selecting the right equipment
Selecting the right equipment can be a complex process and your decision will be influenced by many factors including purchase price, the drive's ability to improve system efficiency, the load profile of the application, and special features you require, such as load braking.
The most appropriate drive will depend on application and process requirements and technical characteristics. Determining the suitability of an application for drive installation is a specialist skill. VSD or motor suppliers can often provide you with detailed information on the suitability and economic viability of using VSD in your applications.
Getting support from suppliers
Selecting the right supplier is as important to the success of the drive installation as considering the technical characteristics of the drive.
A good vendor will provide support at the design and evaluation phase, as well as technical support during the installation, commissioning and operating phases of the equipment, throughout its life.
The availability of service engineers is critical since downtime can be minimised if an engineer is available 24 hours a day, 365 days a year. To make the right decision about suppliers, you need to take into account factors such as technical capability, support capability and history, testing facilities and equipment stocks.
