The invention relates to an improved controller for a power supply circuit of a superconducting motor, a superconducting power supply system for a motor and an aircraft comprising such a system. There is provided a method performed by a controller for controlling a power supply circuit of an electric motor, the power supply circuit comprising an inverter supplying power to the motor via a power supply link, the control method includes: detecting an increase in a voltage across a terminal of the power supply link while overcoming an inductive component of an impedance of the power supply link; and suppresses an output for controlling the inverter if the voltage increase exceeds a predetermined value for a predetermined duration. The invention also relates to a controller device for a power supply circuit configured to perform the method. Accordingly, it is possible to quickly and reliably detect the occurrence of a quench phenomenon on the superconducting power supply link of the motor. The invention also relates to a power supply system for a motor and an aircraft comprising such a system and a control method.
