Motor Sales & Sizing
Tell us the duty and we will size the motor properly the first time — output, poles, frame, mounting and enclosure to suit the application, not just the nearest kW on the shelf.

Service & Support
We do more than sell you a box
Sizing, repairs, conversions and commissioning — the parts of the job that decide whether the motor lasts.
Workshop Repairs
Our Whanganui workshop takes on repairs, bearing replacements and fault diagnosis. If a motor can be economically saved we will tell you; if it cannot, we will tell you that too.
Motor Conversions
Foot to flange, flange to foot, terminal box repositioning and shaft modifications carried out in house so the replacement fits the existing base.
Starter & Drive Setup
Starters supplied with overloads set, and drives parameterised for your motor and duty before they leave us, so installation is a straight wire-in.
Breakdown Support
Plant down? Give us a call. We hold serious stock, and we would rather help you get running today than quote you next week.
Trade & Hobbyist Welcome
We supply electrical contractors and industry every day, and we are just as happy helping someone sort out the motor on a lathe or a bandsaw.
Need a motor today?
