3 Phase AC Drives

Three phase AC drives — also known as three phase variable speed drives or inverter drives — are the industry standard for controlling the speed and torque of three phase electric motors in commercial and industrial applications. Whether you’re managing a pump, fan, compressor, conveyor or HVAC system, a correctly specified 3 phase drive delivers precise motor control, meaningful energy savings, and extended equipment life.

At SDS Drives, we supply a comprehensive range of 3 phase AC drives from leading manufacturers including Parker, with units available across a wide range of power ratings — from compact sub-1kW drives through to high-power industrial frames suited to demanding applications.

Unlike general distributors, we take a consultative approach. If you’re unsure which drive is right for your motor, your application, or your existing control architecture, our team can advise — helping you avoid costly misspecification and get the right unit first time.

All drives are available to order online, with fast UK despatch and technical support available before and after purchase. Browse the full range below, or visit our AC Drives page for a broader overview of the variable speed drive ranges we supply.
