Variable frequency drives and motor control spares

Variable frequency drives are among the most energy-intensive components in any industrial plant, controlling everything from pumps and fans to conveyors and compressors. When a VFD fails, the impact extends beyond the drive itself — production stops, motors run uncontrolled and energy efficiency drops. South African plants facing rising electricity tariffs from municipalities and Eskom are increasingly aware of the total cost of drive ownership, making timely spares sourcing and correct replacement selection critical to operational budgets.

Choosing the right replacement drive involves matching several key parameters: supply voltage, motor power in kW, rated output current, and the fieldbus or I/O requirements of your control system. A like-for-like swap using the existing nameplate data is always the fastest path, but when the original drive has been discontinued, our engineers can cross-reference to a current model that fits your motor and mechanical load. We also supply the accessories that make a drive installation reliable — braking resistors, line and output reactors, keypads and communication option cards — so nothing is left to chance when the replacement goes in.

For urgent breakdowns, we understand that every hour of downtime carries a cost. We prioritise machine-down requests and can often confirm availability on common drive platforms from local stock, with courier delivery to your site the same or next day. For larger or less common drives, we provide realistic lead times and can discuss interim solutions such as a temporary rental unit while your permanent spare is sourced. Our fault-finding team can also test suspected failed drives to determine whether a repair is more economical than a full replacement.
