Replacement sensorless controller for 2012 Brompton

[BromptonJohn]

Hi all,
I have an old brompton with sensorless 3 wire motor and need a replacement controller.
Current controller is an ORT EN15194. Rated V=36V, Low voltage protection: 30V, rated current &A Max curent 12A from 05/2012.
Can someone suggest a suitable replacement?
Thanks, John
