Next generation AC drive technology

(See Sprint Electric at Machine Building North, 13 May 2026, on stand 121)

Generis uses a patented switching technology that does not require a DC link. This means Generis gives full four quadrant control as standard, as well as unity power factor and minimal input current distortion. Four quadrant control removes the need for active front end drives or braking resistors, simplifying control of AC motors in complex applications.

Removing the DC link in an AC drive also massively reduces harmonic distortion to the mains supply as well as improving drive efficiency. The drive will control all AC motor types with both open loop and closed loop available to maximise its range of application.

Generis drives will be available from February 2024 up to 22kW with additional sizes being introduced over the next three years to cover a range up to 200kW.

Gary Keen, managing director at Sprint Electric, comments: "Generis boasts simplified mechanics and does not use electrolytic capacitors, so it has no life limiting components which degrade with time and temperature. This results in exceptionally high levels of reliability as well as minimising total cost of ownership.

"Constant torque and variable torque profiles are easily selected so offering full energy efficiency with short payback periods. Generis also includes extended frequency output, a feature often sought in constant power applications.

"This release has been a long time in the making, and the team has worked exceptionally hard to produce this leap in drive technology. Generis represents a new level for AC drive technology."
