High-efficiency motors pioneer David Walters has died
Published:  16 December, 2021

The death has been announced of Professor David Walters OBE, former technical director the motor manufacturer Brook Crompton, who was a pioneer of high-efficiency motors and led the development of Brook’s World Series (W) motors which won a Queens Award for Industry.

Professor Walters was also played a key role in a joint project between two trade organisations – the AEMT in the UK and EASA in the US – which examined how motor rewinds affect efficiency. The study, which found that electric motors can be repaired or rewound without losing efficiency, led to the publication of the Good Practice Guide to Maintain Motor Efficiency, which now forms the basis for an international repair standard.

In 1997, Walters was made an Officer of the Order of the British Empire for his service to energy efficiency. He published numerous articles on the topic – including several in Drives & Controls.

In 2019, Prof Walters was presented with a Lifetime Contribution Award by the AEMT in recognition of his work on energy efficiency and motor design. He was pivotal in many technical developments for the association and for the motor repairs industry as a whole.
