Variable Speed Drives and Soft Starts

Control of electric motors by simple on/off switchgear covers a wide spectrum of applications for machine drives. However, this method brings about certain constraints which can prove to be awkward for certain applications, namely: * Constant speed operation * The current peak during starting can disturb other equipment connected to the supply * Sudden mechanical jerks during starting can be unacceptable for certain machines, or for the comfort and safety of the users Soft starters and electronic variable speed drives eliminate these inconveniences. Designed to control A.C. or D.C. motors, they offer progressive acceleration and deceleration, and provide precise speed adaptation to the operating conditions. Depending on the type of motor, the drive can be one of three types - controlled rectifier, voltage controller or frequency invertor. We offer a wide range of variable speed drives and soft-starters from a carefully selected list of manufactures, ensuring you receive a quality product at a competitive price.
