Generally the virtually same control can be done using AC and a Triac with phase angle control, how it is typicallt done in power tools/equipment etc.
That circuit looks as if it would be better suited to a P.M. DC motor.

Look up the data sheets from STMicroelectronics, ST6210 and the PDF controlling a Universal motor with IGBT.
also STM AN885
